[Q] USB unplugging - Acer Iconia A500

One more question to you guys - when I connect a USB flash stick to my Iconia, it flashes its LED a lot. I copy what I need using Astro or whatever and want to remove it. However, I noticed that if I remove the stick while its LED is still flashing (= it's still in use), the tablet will not wake up on the first power-button press after it goes to sleep for the first time after this unplugging and that it won't recognize the USB stick anymore before I restart the tablet. The only way around this, I found, is to wait for the ~2sec window of LED not flashing to remove the stick. Anyone else had this issue? And if so, how do you get around it? Is there a way to unmount the flash drive easily? Perhaps a widget or so?
Thanks y'all

I noticed the same thing when using an USB. I just wait until it stops rapid flashing before removing.

I just noticed this major issue yesterday. If i leave my USB flash drive in the device and go on hibernation mode, the next time I wake it up the USB flash drive will keep flashing as if it is reading the drive. As it turns out, it is actually deleting files. I've run several tests to confirm this. Has anyone else had this issue? It's impossible to get a hold of Acer tech support.

I have been having a similar problem with my A500 seemingly deleting files. I have been using File Manager HD to transfer files between my external SD, internal SD, and my USB flash drive. I began noticing files disappearing during transfers to or from the USB drive, or ending up empty sometimes when they would paste into a new location.
I had an occurrence recently moving an MKV file from internal storage over to the USB. In the middle of the transfer the File Manager HD screen went blank, then showed my USB drive as empty. I exited out of that and came back, it showed all the files back in the USB, except the new video file was showing 0kb in size. It had lost the entire file during the transfer, and it was no longer in the original location internally. This leads me to believe it may not be an issue with the USB, but with File Manager HD. (So far I have lost 3 complete seasons of Big Bang Theory as well as many movies and personal work documents.)
I began running transfer tests using Root Explorer and so far I have had 0 issues similar to those encountered with File Manager HD. I have moved several MKV and other files back and forth at will with Root Explorer and so far, 100% success.
I would recommend if you are using File Manager HD, tread lightly for the time being to see if that may be your issue as well. Or just move important files with Root Explorer.

For the flashing issue - some flash drives don't have a light (we'll ignore them).
Other have a light that's ON all the time, as if to show it's got power (bloody useless!)
Others flash their light when the drive is being accessed (read/write).
If your drive flashes, it's safe to assume you should NOT take it out - something is accessing the files, either reading, cataloguing, or writing.
I don't know is the A500, or HC, caches writes like windows does, but it MIGHT, and pulling the drive when it's flushing the cache will KILL the file (Probably both - the file being moved from and the destination file as well).

You guys/gals need to catchup on (?) in the DEV section more often

"* Requires root and busybox."
I'm not faffing about trying to root the A500 just for a mount app, only to find a new update kills the tablet because of the root.

the previous update didn't kill the tablet because it was rooted. And always have the option to unroot before taking an update, if you want to be extra precautious.
or just wait till Acer fixes the issue..

Yup...

having root does NOT prevent updates... only when you go and renamed or deletes system files...etc

ROM Failure....Suggestions, please?

Well, I should have listened to myself. I was going to stick with the stock gtab because of the dangers of modding a new ROM. I even started a thread about keeping my tablet stock.
But stock is so messed up and so hard to work with I decided to go ahead and mod Roebeet's 1.01a version.
It installed the first time. Then I reset the data from the Security Menu. Seemed to be running, but the Tnt side didn't work. Worked from the new Launcher menu and I thought I was home free.
Then it went off and automatically came back on, then the VS birds, the GTab, then birds, then tab.....off button no longer turns off....tried redoing the ROm again....no change....tried again....no change.
Loaded CWM 08 satisfactorily. Tried cleaning the data as suggested in threads. No change. I put 2.20 on another sd card. edited it for SDCARD2. Now I can't get CWM to see the external card to load it.
It did load CWM from SDCARD2!
I'm sure there's something I don't know or have done wrong, but I'm stalemated for the time being. Can't shut the machine off, so just have it idling on AC power.
Can anyone tell me how to get CWM to load from the SDCARD2 so I can see if TnT 2.20 or something else well work?
I'd appreciate suggestions. I knew I should have stuck with stock -- but didn't listen to myself. My bad!

it will take you back to stock and you can start again.
Im pretty sure you just need to repartition the sdcard. Its under advanced in cwm.

CWM .12 (the newest one) actually reads from the microSD. But (and this is a big BUT) it has issues with non-padded boot.img files, which is what TnT Lite, and TnT stock based 1.01a1, and stock itself, use. So it's a double edged sword. I still use .08 because of this issue.
I would also recommend the SD card re-partition. You have cwm already so you are halfway there. Worst case it's nvflash time - I have a post on that process, as well.
Fate Zero,
Thanks for the quick reply. I had that post laying on the desk before I even started. It wouldn't work because the G-Tablet would not read or access SCCARD2 as I mentioned in the first post.

GideonX,
It wasn't that simple, but your suggestion was part of the solution!!! Thanks!!!

P. S. -- See answer to Roebeet for more info.
Roebeet,
I am back up on TnT 2.20 and your suggestion was a part of what I did.
I really believe something messed up the SDCARD2 operation. After I loaded CWM that way, I couldn't get it to work anymore and so the re-installs keep just trying to load the faulty 1.01a setup.
But here's what I did.
I found the USB option on the Mounts and Storage menu in CWM. I plugged in the cable to mini-USB and my PC. I mounted/turned on the USB and the drive popped up in Explorer on the PC. I could see the old "Update.zip" file and "Recovery" folder on the SDCARD (the ones for 1.01a) and so I erased them. I then copied in the TnT 2.20 files and shut down the links and went back to the G-Tablet and CWM. Still wouldn't work.
So I went to the Advanced menu and re-partitioned the SDCARD -- 2048 and 256 as everyone suggested. Then I just went down the menu in CWM and formatted all the system/cache/sdcard/etc. folders. Then I went by to the USB-PC connection and loaded the ROM files into the newly created and formatted SDCARD folder. Went to the other menu item and told it to apply the zip file -- which it immediately did setting up TnT 2.20.
That rebooted and I went through most of the basic setup, got wireless working, web, etc.
Only problem is I need to get Root Explorer installed to do the Market Fix, and when I went to ES Explorer to go to downloads and install it, it didn't find it in the market. So I will have to figure out a way to install or use something that will let me install the Root Explorer apk I have in the "Downloads" directory on the SDCARD.
I will try to re-think this account and re-write it more accurately when I'm not so bleary-eyed and thick-headed. I have not seen a G-Tablet account of someone rebuilding using the kind of "side-loaded" method I scrabbled together.
Suggestions on how to get to the downloads directory to install apps?

Bleary eyed as well (time for sleep) -- I personally use Titanium Backup for the (primary) Market fix. Has worked every time and I've done it a alot, as you might expect. I'm not sure why the file manager won't let you run an apk from the downloads section, but I believe you can download (and run) the TB apk right off their web site.
I'm guessing from the root explorer comment that you are trying the additional Market fix, for even more apps? Maybe you can get it working enough with the primary fix, to get root explorer? I see it in my own Marketplace, although it's not a free app.
Sounds like you are getting there. I replied back to your PM but I guess I saw it a little late
I was hoping you wouldn't run into a bunch of issues when I wrote you back. You will get it. I think you are almost there.. And I have been in the same boat myself a bunch of times. Nothing like thinking you just wrecked your new toy....
You can use the microsd to load the Vanilla with ClockworksMod, but you are still in a boot loop. So, like others stated format the internal SD. Then use your USB mount option to copy over the stock rom and flash. This will get you back up and running.
Reboot, install TNT lite using Clockwork, reboot, skip Google sign in. Install Titanium and clear that google process. Create a Google Account and reboot.
Market should work after that.

All,
Thanks to those who replied for help, moral support, suggestions, and whatever.
I have been up on 2.2.0 ever since the malfunction that started all this and now have added my desired software, etc.
Bottom line is that with this experience I now think I know enough to hold things together and do whatever testing I want to do. I hate to have learned it the hard way. And I wish I had known enough about CWM to load it first and preserve the stock hardware on it.
I will say that IMHO the G-Tablet rocks. Yes, the screen is substandard, but I usually hold it in front of me or set it up on a stand anyhow. And straight on it's not bad. I will keep following watching for a screen mod.
Again, thanks all.

DL09 and Mac OS USB Mounting

Just got to a mac to give this a shot. Doesn't mount for me either! Shows a CD image with some of the pc installer files but not the directory of the phone itself. Very interesting. Upon unmounting, got a "The disk you inserted was no readable by this computer." message.

Same issues here! I am hoping one of you AWESOME developer types can help us Mac users out on this one. I have made multiple inquiries to both Verizon and Samsung regarding this issue. Surprise, surprise...they each point the finger at the other! I pretty much lost all hope when the last Verizon rep I spoke to suggested I purchase an external SD card reader to transfer files...gulp!
Same problem !!!
Doesn't work with my Mac. Also tried Factory Reset.. still doesn't work....
Looks like I am not the only one ....
Also, the update left a weird status icon on the top next to my 3g icon in the status bar.
Please help..
Thanks,

Hey, I think I may know what the problem is, even though I don't have a Mac to test. I'm running stock ROM with DL09 OTA, and I discovered that when trying to mount the phone in mass storage mode, it wouldn't. It just showed up as a CD drive that contained an installer for the latest samsung drivers, and an app that opens IE to a page to download some kind of Verizon VCast media manager app. In other words, Verizon is trying to save you from yourself by forcing you to use their crap media manager software, instead of accessing the contents of your SD card directly.
I then realized that I hadn't de-bloated by removing all the Verizon apps, so I froze the VCast and VZNav apps (and Bing, and a few others) in Titanium Backup, and after that, Windows will now recognize and mount the SD card as expected.
I suspect that the funky CD mode thing is what is messing up mounting it on your Mac, so would suggest that you freeze those apps on your phone (you can also go in with ADB or Root Explorer and rename the .apk files, if you don't have Titanium Pro), and reboot the phone, and then try mounting it again.

Can anyone confirm that this works? And particularly: which app needs to be stopped/"frozen"/removed for the fix.
I had searched a half dozen forums and not found a solution, that you found a fix is great news.
Not being able to access the SD card as a USB flash storage device is absolutely intolerable - I would say it's a serious flaw with DL09 and Verizon should "recall" the update or QUICKLY release a patch that "un breaks" it. The fact that they're probably doing this on purpose is sickening and infuriating.
I later confirmed that that doesn't fully fix the problem. The issue is in the kernel itself. Adrynalyne's 1/18 or later kernels fix the problem, at least for Windows, not sure about Mac, but there's a good chance it will. Try that and see what happens.

[Q] Custom ROM bugs? Help!

Hi.
I'm running SyndicateROM Frozen 1.1.1, and I've observed several bugs. I need to know if the bugs are the fault of the ROM (and thus something I should take up with the ACS developers) or if they're my fault due to something I'm doing wrong.
1) I use folders on my LauncherPro* homescreens to organize apps. For this example, I'll use my Games folder. In it, all the games except 1 are installed onto my microSD card. After I drag the icons to the folder the first time, they are fine. However, after a reboot, the icons of the apps installed to my microSD card that are in folders change to the generic Android green/white icon. The apps still load properly, and the icons appear fine in the App drawer.
*LauncherPro is included as the only homescreen in this ROM.
2) I'm having an odd issue with Plants vs. Zombies. It loads to the main screen, and I can manage the player names, but after I click to start the adventure, it locks up with the Adventure button depressed. The main screen music also dies. No FC/wait dialog appears. I have to press the Home button to get out of it. PvZ is unplayable in this condition. Rebooting does not help, nor does formatting /cache or Dalvik-cache in custom recovery.
3) JuiceDefender Ultimate tells me in the log that it cannot toggle 2G/3G data, and that this is likely to be a kernel issue. As far as I know, this reduces the effectiveness of JD.
4) In ClockwodMod Recovery 3.0.0.6, I cannot mount my microSD card for the PC to read/write it. I get "E:Unable to open ums lunfile (no such file or directory)". I've seen posts that indicate this is a bug that was corrected in later versions, but I don't know if the custom ROM I am running is compatible with later versions,or where to find later versions. EDIT: I found CWM 3.0.2.5, and flashed it. It still reports the same error when attempting mount my microSD card for my PC to work with.
5) When I connect the phone's cable to my PC and get the the "Charging/Mass Storage/Tethered" popup and click Mass Storage, and then click "Turn On" at the next screen, it appears to work fine, except that my PC shows no new removable media drives. Sometimes, even though I touched the "Turn On" button, nothing happens. The button does not turn into a spinning wait indicator, nothing.
6) I found a post (that I've since lost track of) that purported to provide instructions to see if journaling was enabled. (I'm already formatted as EXT4). The instructions errored out, apparently because I have the wrong version of tune2fs. I'm not sure how to copy the correct version over, so I flashed the "Journaling On" zip shortly after I re-flashed this ROM. Does EXT4 and journaling stick between ROM re-flashes?

OK can only answer some of these. I heard Launcher Pro can take a little while to read icons from the sd card. You may want to download and try Zeam launcher.
The Plants v Zombies may be a result of overclocking/undervolting. Try it again with no undervolting and your speed set to 1Ghz max and 200 Mhz min.
Not sure why you are mounting the sd card in clockwork. Sounds like either your cable is flaky or you need to reinstall the Samsung drivers to connect your USB. Also try different USB ports and turn USB debugging on. I had to reinstall the drivers for each port on my laptop as it would only recognize my phone in one of them originally.
No, journaling does not carry through other ROM flashes. If you flash a no-journaling ROM, you will have no journal unless you turn it back on. Some can be turned on simply be making a nand backup then immediately restoring it. Others work fine with the journal on flash. And some are more special and need a specific script like Bonsai.
Hope some of this helps.

1) you can get a different launcher from the market. I've never had any luck with pushing apps to sd.
2) that's a issue with the game. Try changing your max and min cpu.clocks. If you uved you may be to low.
3)jd is a pos and you don't need it. I go on average of 12-16hrs a day with 3+ hours of screen on. And a synce interval of every hour
4) no versions of cwm on the epic has allowed you to mount your sd to pc for the epic. Cwm was ported to the epic and not created by koush him self so some things are broken.
5) try a different cable and usb ports. This is a known problem even while on a stock rom
6) yes it sticks unless the rom your flashing changes it.

[Q] Way to access mounted SD card through windows?

As the title suggest, looking to see if its possible to read/write to the mounted sd card while its plugged into the Iconia Tab from my Windows file manager.
about 4 months ago i found an old Sandisk sansa at work, no one claimed it so the manager in charge of lost and found gave it to me tonight. Its a fairly old model, but it had an 8gig Transcend micro sdhc in it. its loaded with nearly 7 gigs of music. Id like to back up the contents and then wipe the card.
Also, is there a way to test the cards read/write speeds from the tab? i saw Sd Tools but it only tries to speedtest the internal memory with no option for switching to the external_sd.
Or, am i going to have to buy one of those little card readers for USB slots?
@Grimcreaper - you could look at this method I posted back in July. It's simple and it works. But I'll be honest for simplicity I prefer using a usb card reader, I know it's a nuisance taking the sd card in and out but virtually nothing can go wrong while you are using it.
Try this simple method
For anyone who wants to see the contents of their sd card on their PC and be able to copy/transfer files from one to the other, why not give this a try, it is very simple and works for my A500.
Before you start you need your A500 to be rooted and you need "USB Mount All version 1.3" from the Market cost $1.99
(1) Have your PC switched on, don't connect your A500 yet but switch the A500 on.
(2) Run USB Mount All and you will see your sd card as a "Device" named "ext_sdcard".
(3) Press the tab "Mount" next to your ext_sdcard. You will see two messages "Mount has been granted Superuser permission" and "Device successfully mounted".
(4) Press the "Menu" tab in the top Right hand corner of the screen, this opens a small box entitled "Settings". Press on "Settings" and you get 3 options, make certain all 3 options are ticked, ticking them if they are not. (The important thing is to have "Mount on Bootup" ticked"). Press the Back Arrow twice to get back to Home Page or where ever you started from.
(5) Re-boot the A500 and after it is back running connect it to your PC using mini usb connector.
(6) Now check your PC and open Windows Explorer, you will find under your A500 Device most of the folder/directories that are in /mnt/sdcard (which isn't all that relevent to this) BUT importantly you will find a folder/directory entitled "ext_sdcard" which for those of you who noticed is the exact name that "USB Mount All" called your sd card.
(7) Now use Windows Explorer to copy and paste whatever you want into the "ext_sdcard" folder.
(8) Please note that when you start to copy files you will get up a warning box stating "Do you want to copy XXXXX to your device?". You are given 2 choices (1) No skip this file or (2) Yes.
(9) Put a tick in the box at the bottom Left and click on "Yes".
(10) When finished safely disconnect your A500 from your PC and re-boot your A500.
(11) After re-boot go back into "USB Mount All", chose top Right menu and settings box and remove the tick from the 3rd option "Mount on Bootup". Each time you are going to copy, move or delete files first of all put the tick back in the 3rd box and when you're done take it out.
Your Done. If you use any File Explorer to look at /mnt/external_sd you will see all the files residing on your sd card including those you've just copied
DroidExplorer
Just wait for or load one of the 3.2 based roms...
Thank you guys for your answers
Yes you can!
I'm using the virtuous galaxy room and it's under the storages fileĀ» sdĀ» mmcblk1 and there you go. Way easier than pulling the card out every two seconds
@Grimcreaper - Further to what I originally posted, I have to apologise and endorse what "verdigny" posted. "DroidExplorer" is IMO the best and easiest way of achieving your goal. I must blame an early onset of Alzh or alternatively too many visits to the bottle for forgetting that I in fact have DroidExplorer on my PC and it does everything you want so easily. Back in July when I posted my screed I hadn't seen or downloaded DroidExplorer and that is why I worked out that painfully long and convoluted system.
Thanks again for more info would have responded sooner but ive been stuck working some killer hours right before my vacation kicks in.
Another question, anyone know how to test the speed of the micro sd card?
I found 1 app but it only works for phones i think as it only shows the tabs internal memory with no options for doing an external sd card source, cant remember what its called as i uninstalled it
trying to find out if its worth using on my tab or if its to slow.
Gonna edit this again, appearently i didnt fix it. BusyBox doesnt want to work on my tablet now. says its not rooted and wont install it. so im lost
Went into SU and had it "forget" the busybox installer, but its bringing up a lot of things it didnt the first time i installed it..
Is there anything to worry about with an install of busybox? is it easy to remove if i need to for updating the tablet or anything once i remove SU access? all of these warnings have me a bit scared since im a total noob with android devices but being able to access the sd card constantly through the tablet from windows would make things a lot easier
@Grimcreaper - can't help with sd card speed, a bit out of my league. As far as "BusyBox" is concerned may I make the following comments. I presume each of the following statements are true.....(1) you are using the stock/standard Rom and Kernel (2) you have rooted by using Iconia Root [ v1.1 or v1.2 or v1.3] (3) you are on Honeycomb 3.1 (4) you use "RootChecker" free from MktPlace (5) you used "BusyBox Installer" free from MktPlace.
I am not an expert but in your position my "path" would have been......(1) Root the A500 (2) Apply BusyBox Installer (3) Install RootChecker. Assuming Rooting goes ok you should have no problem installing BusyBox and then use RootChecker which in it's "Advanced" mode will confirm your Root was successful and will also confirm successful installation of BusyBox. By installing BusyBox, apart from anything else, you gain access to certain system/scripting/"linux type" commands such as 'cat' 'chmod' 'chown' 'clear' 'dd' 'egrep' 'ping' etc.etc.
If you need "Iconia Root" I can point you to the XDA page or can attach it to a followup post, but reading your post again I'm presuming you already have it. A small point, when it comes to updating OTA updates from Acer I found on the last update from 3.01 to 3.1 that after restoring certain "bloat" files I was able to update without uninstalling Root and at the conclusion of the update Root was still operative.
Hope I havn't missed your point and wasted your time with a load of drivel.
Quick addition - Do a search in Market for "software data cable" and look at the first 2 free apps. Haven't tried them myself but might interest you.
Checking out rootchecker now, everything else on the list is accurate.
According to rootchecker i am rooted, which i did using the iconia root 1.3 i believe some time ago to get the netflix stuff working by backing up replacing the libmonv file.
It also shows Busybox as correctly installed too, version 1.18.4

find a pc program to download and check it.
here are a couple,
Crystal Disk Mark

HD Tach is a low level hardware benchmark for random access read/write storage devices such as hard drives, removable drives (ZIP/JAZZ), flash devices, and RAID arrays. HD Tach uses custom device drivers and other low level Windows interfaces to bypass as many layers of software as possible and get as close to the physical performance of the device possible.
The trial version of HD Tach measures the sequential read speed (at various points on the device), the random access speed, interface burst speed and CPU utilization of the drive. The registered version adds sequential write testing.

Can't write to the nexus 7 internal

For some reason I cannot move files via Windows 7 file explorer to the Nexus. I can and have done this on every other mobile device that I've had before. What's the difference? Why can't I place pics and videos on it?
A few more details would be super helpful to give you a good answer. Start with if you are running a custom ROM and what if anything you have tried to solve the problem.
When you plug in your usb look under settings - storage and see if there is the option to mount storage.

For some reason, now it's letting me even though I didn't change anything. Mods can delete this if they want. And thank you ezas for your reply.
Glad you got it sorted out.

In my limited experience using MTP (rooted stock N7 4.2.2 + Win 7 x64), what seems to work well is:
- copying files FROM the N7 which were already in the /sdcard mount point when the N7 last booted,
- copying files TO the N7 into a folder which already existed inside the /sdcard mount point when the N7 last booted.
(I should also point out that moving files this way seems to be 5-7 times faster than using "adb push" or "adb pull")
What seems to only work sporadically is trying to copy or write to things which were "recently created" in the /sdcard mount point. For instance, if you generate a large set of files using Android, you won't be able to find them from the PC until a seemingly random ? amount of time later. Similarly, if you create a folder on the N7 (let's say by using a file manager) with the intent of pushing some files there from the PC, you won't see that folder show up in a reasonable amount of time.
This behavior actually does make sense - in principle, it is impossible to allow instantaneous write access to a file system from two independent hosts without running risks of filesystem corruption. In previous versions of Android, external SD cards could be accessed using USB Mass Storage drivers, but only exclusively by either the Android device or the PC - never at the same time. The SD card had to be unmounted from Android in order to be seen by the PC.
But, what is curious is the delays involved. I wanted to do something similar to this the other day (copying a nandroid backup from the PC to a "new" folder on the N7), and thought that by correctly disconnecting from the PC followed by reconnecting to the PC would allow the newly-created folder to "show up" via MTP on the PC. No such luck however; I needed to reboot the N7 for that to happen.
Bottom line is that MTP will work (and quickly, too! - better than 10 MB/sec) - but only with the above limitations in mind. When in doubt, reboot the N7.
