Problems with file copying. - Nexus 7 Q&A, Help & Troubleshooting

Hi perhaps some of you with a Nexus 7 can help me.
I've recently got a 16GB version but I seem to have strange problem with copying data to the device. For example, if I have a folder of photos I copy over, either over wireless or using USB MTP all the copied files on the device have had their modification dates altered to the exact time of the copy procedure - each file has a second difference between them with all the same date. The files on my computer have there correct modification dates on them.
This happens with all types of file; video, pictures, zips etc and also under Windows and OS X. This doesn't happen on my SGSII with a custom ICS ROM running 4.0.4 but I connect that via USB Mass Storage and not USB MTP.
Any ideas? Why would USB MTP alter the files in this way? It's making organisation and sorting a nightmare.
My Nexus 7 is rooted, unlocked etc using the Toolkit.

From what I understand, this is a file system issue. Fat32, which is what's used by your phone with UMS, will preserve the original timestamp, but I believe that ext (still not sure if it's ext3 or ext4), which is used by the Nexus 7, will use the file creation time as the timestamp.

Seriously? That's crazy! Is there no way to change that? Surely this is a major flaw. I have photos etc which must retain there original timestamps.

It's a problem inherent to the file system used. I believe that there might be a way to do the copying on the Nexus 7's end and use some type of command line argument to preserve the original timestamp, but this would require you to mount a storage device to the Nexus 7 via USB OTG to copy the files from. It would also require someone with Linux experience to tell you how to do it because I have almost none.

All that just to copy some photos over? No wonder people buy iPads. Guess this tab is going back to Google. No way to format it as FAT32? Also, if it's using EXT, why is the individual file size still limited to 4GB?

Nope, you can't format it to FAT32. Someone with more Linux knowledge than I have will need to answer your 4gb question (I've been wondering about it myself). Maybe someone else has another easy solution to your timestamp problem that I'm not familiar with.

[q] guys need help!!!! Plz reply fast

i am using the sd version of the AmeriCanAndroid AOSP HD2 GB2.3.5 CM7 and i cannot copy the files through usb ie it gets copied and then when i disconnect the copied files are not visible .......and sometimes they even get deleted ...So plz tell how can i get over this ????
You could transfer the files via Dropbox, the link below in my signature will get us both extra storage space.
welll i can copy but they r not visible or getting deleted ......
Are you copying the files to the sdcard? And what app are you using to browse for them once you have transfered? Root Explorer is the best file explorer imo.

Are you removing the usb device safely?
Usually if you copy files to the SD on android they will not be visible until you restart the device. You can make the media files visible using some apps, but other files will only appear after you restart.
Apparently, when copying files using My phone explorer, the app seems to make android update it's information and thus files you copy using My phone explorer will appear when you finish.
I have tested this with most sense builds, but not with Amercian Android.

This is false.
When you copy anything to Android's SDCard via USB/WiFi, the device immediately sees the files.
When you copy media files (pics/music/movie), the device sees the files, but the Media Service might not have indexed the files yet, so media apps relying on the Media Service will not show them (Music app f.e.)
IF you're copying files to the SD card via USB, safely removing the device from your computer, and they still do not show up on Android's File explorer, then i would check your SD card for errors...
P.S. Tested on HTC Kaiser running froyo/gingerbread, HTC Diamond running Froyo/Gingerbread, HTC HD2 Running gingerbread, HTC Desire running Gingerbread, HTC DesireHD running froyo/gingerbread. Multiple SDcards raging from 1gb to 16, class 2 to 10.
With americanandroid on SD, Theres a problem with usb files transfer (check FAQ'S on thread), u can do: reboot to wimo, copy files and boot android, files will be there, OR use the program for windows described in the FAQ (guess its Androidmanager) OR.. Use NAND Rom... ;-)
Hope it helps

I like that you tested it on multiple devices, but they're all running Android form device memory if I'm correct, right? you're not running SD Android. anyway I tagged a long and scanned my SD for errors and nothing was there. Using wifi and bluetooth makes android recognize the files, and yes media files have to be reloaded.
however, when copying non-media files through USB on several build I've tried before (can't remember which because I've tried almost every SD build out there) the phone will not see them even using a file browser, but they would appear on the PC. Resetting the device would make them appear. My only explanation to that was that certain builds would create some kind of "image" of the files on SD at the time, and would show you that image when you request the files. So if you add files using a way that doesn't update that image (here copying through USB) they wouldn't appear until the next start.
try samba filesharing from market.
you can copy files via wifi without usb.
Or you could use a card reader......
dropbox is great for transferring files wirelessly too

HTC Kaiser run android from sdcard (either SD partitions or image files on the main partition) long before there was nand.
I understand what you're saying, but i cannot accept it. It makes no sense.
Let's see, Android requires a minimum of 2 partitions, one for data, one for system. Those might be a SD card partition (in this cases), or 2 files on the SD card mounted using loop.
IF, you're using the second option, you cannot access the sdcard on the computer (it must be unmounted from android to appear on the computer, you probably noticed that it's impossible to access the sdcard when it's connected via USB as mass storage.)
So, you're probably using SD card partitions. Am i right?
it might be permission issue...

sorry didn't notice the Kaiser on that list. I don't use SD partitions, too lazy to do so, and I don't unmount the SD, had my share of troubles doing so in the past, I used apps like Dualmount SD and such, media files would appear after I force android to rescan media, but other file types would appear after I restart the device. So I came up with the best possible explanation. However, when I copy files with My phone explorer they always show up, whether media or not, could be the new build I'm trying, or could be that I'm doing something I didn't in the past, who knows.

USB OTG to mount Galaxy Nexus?

I'm looking to mount my Galaxy Nexus to my Nexus 7, but when I go about it like I would a usb stick stickmount doesn't see the sd card. My USB OTG host cable works perfectly with my 64gb SanDisk Cruzer thumb drive, but it is NTFS formatted to get around the 4gb file size limit. I can read files, copy files off of it, and stream files from the stick just fine but I am unable to write to the stick. I'd like to be able to get rid of NANDROID backups, playstation games, other large files, etc without having to connect to a computer.
1. What format is the "SD card" on the Galaxy Nexus? Is it ext3/ext4 which stickmount can't read?
2. If there is a better way to make an NTFS formatted writable stick I'm all ears...
3. Maybe I should just get a smaller separate stick that's FAT32 and thus writable...
Nokia?

I haven't seen that done with Android devices just yet... maybe it's possible, but I haven't heard of it. I know that Nokia phones can hook up as external storage to the N8 (saw a video on YouTube) but that's as far as I know.
Also, to write files to an NTFS volume on Android, it seems that you need to add the "fuse.ko" to your kernel (in /system/lib/modules) I tried doing this with the Nexus 7 ToolKit, but I wasn't about to insmod it (make it run) since the fuse.ko I has was apparently for a different version of Android??? I've literally spent about 10 hours "searching" on xda and all over the internet. It seems (oddly) that everyone in the Android community is content with a measly 32GB total limit, and 4GB file size limit. *(facepalm)*
This won't work. Android, with 3.0, stopped exporting storage via SD card, because of reasons[1]. If at all, you can have a vendor modify Android as to export your plug-in SD card, but not the internal storage.
Currently, Galaxy Nexus etc. offer their files via the 'MTP' protocol when plugged in, and there's no support to act as an MTP client AFAIK (since Linux support for MTP sucks balls).
[1]: since a separate storage for /data, /system etc. was considered uncool, as it made you dependent on a predefined partition size (remember 256MB 'internal storage' phones and Android Market "uninstalled due to low disk space"?), newer phones, and especially the Nexus line, features a single storage container.
The USB mass storage interface works like plugging in a hard drive into your system: it gives you block-level access, and this is usually synonymous with "exclusive" access, as it results in destroyed or confused file systems if two independent systems try to mount the file system on a storage device.
Problem is that Android still needs to be able to actually run, so it can't give you block level access to the internal storage. The only way that would be feasible is to turn off your phone completely and have the bootloader give you USB mass storage access, which is counterproductive.
Thus the need for something like MTP (which was already around for a while) was born, which gives you the ability to make it look like a file system, but actually work on a client/server basis like FTP.
tl;dr: no usb mass storage ("usb stick mode") with galaxy nexus. ever.
Can't check at the moment, but can't you mount the SD card from CWM recovery on the Nexus in USB Mode rather than MTP?
What we need is a file manager that can use MTP. I'm also interested in hooking my Gnex up to my 7. There must be something out there that can do this.

Galaxy SIII Moving data to and from the phone

I've tried everything I could think of:
Drop Box fails: file size limitations
Direct copy by attaching to a PC fails: IF you want to backup directories such as clockworkmod or something with lots of files, CRC's often do not match for copies
SFTP works: when permissions allow and its slow
Google Drive fails: speed and space available
SMB fails: As I have network firewall issues that block this.
SGS3 Easy UMS fails: Only external SD card
Directly mount SD card fails: Only works for external SD card.
ADB push/pull fails: only moves 1 directory, not valid for an entire set of directories, continually fails on permission issues.
I had a Atrix, which was great worked every time, plug it in mount the SD card's and go, now with a Galaxy SIII I've take I giant step backwards as far as moving data goes as there is no good fluid and stable way to backup the phone or just move data without pulling my hair out and rolling the dice. I'm sure there is some other method, but so far I've yet to find it, so hence any suggestions?
Also I'm not a fan of the new Clockworkmod plan, as it makes backing up the backups to external devices very time consuming and error prone (external backup to an SFTP server has taken 14 hours and is still running), the old single file method from 5.X, took more space but was simple to backup (and fast same backup would have been done in 20 minutes). Can you use the old method in 6.X, if so how?

I don't understand what you are trying to do. Are you just trying to transfer a large file to the phone' s internal memory? If so any of those methods you work without any problem
not sure what cwm vers your using but the cf root version allows for backups to be created on internal or external storage I also have no porblems copying the folder from the extsdcard to pc using mtp connection.
You can flash a separate recovery image with mobile Odin easily, as they are separate from kernel
solved it myself
had same problem also , could not use my s3 in usb mass storage mode with the original usb cable
but it do work when i use the usb cable from my old nokia phone ! you should try with some other cable

Interesting thought, I'll give it a try. Maybe it will help with the desktop transfer, but the real problem is getting 1-to-1 transfers without any conversion from the internal SD, I can copy the directory to the ext SD and then remove it and copy, but as stated that's not practical. Note I often push 3 or 4GB a day and removing the case for each one, would never work. Worse the desktop method does not work under linux (and yes I've tried to get it to work, but its unstable and very slow).

[Q] USB Port?

I have files on several USB flash drives. I purchased a USB to Micro USB adapter, thinking I could then access these files on my N10. I have tried it, and I can't seem to see the USB drive in the file manager. Am I missing something? Do I have to purchase all new micro USB drives? Or is the N10 incapable of this and the micro USB port is only for charging?
Get Nexus Media Manager. It will auto mount the mSD card and allow you to read from it. To be able to write to it you will need to root your device.
OK...thanks. Not what I wanted to hear, but at least I will be able to read the files. I still think this was a stoopid move on Google's part...not providing support for read/write to a USB stick. Bad enough there's no SD card. Good thing I LOVE the tablet otherwise!

Make sure your adapter is an OTG cable. OTG USB cables allow for data transfer and recognition of external devices. As mentioned above the media importer works for Read Only access. You can use Stick Mount and root your N10 for R/W access if necessary.

If this is really an issue, you can always throw on a custom ROM with OTG enabled. Then you get R/W access baked right into the OS. I believe craigacgomez's ROM and Task650's AOKP based ROM both have OTG enabled.
Thanks. I don't think I'm ready for rooting a tablet at this stage of my life. I'll live with using Box.com or another cloud solution. I'm too old to root anything! LOL

Your choice, but it's really easy with a Nexus and there are fool proof ways like mskip's Toolkit that make it a breeze. Good luck either way!
Hello! I have question. OTG will work on stock ROM with Nexus Media Importer, but I be able to only read files? Or I should flash custom ROM and kernel?
You could flash my custom boot image in the dev section and re lock, you'll need to root just long enough to copy vold.fstab to system unless someone mods the stock system image to add it, or creates a update zip you can flash with a temp recovery.
I'll look into modifying the boot image to create the vold.fstab then no rooting is necessary.

How are you "mounting"? You shouldn't use any apps or run anything, it should mount automatically, in /uskdisk or /storage/usbdisk
I've found that not all file managers will give me write access once it's mounted, depends how the FM works. ES usually gives me read-write, Root Explorer sometimes does, other times I have to click "mount r/w", Solid almost always works...
Also bare in mind, my boot image is for 4.2.1 not 4.2.2.
That said, if you don't want to flash the boot image, it's possible to do this by just editing the vold.fstab to point to a directory inside your SD card (which you always have write access to) and it will mount there (assuming you make the directory), no need to modify your boot image.
I use this way now, because I like to switch ROMs and can't be bothered modifying all the boot images. I just make a folder called "otg" in my sdcard directory and modify vold.fstab to mount there.

No problem.
Don't mount with stickmount, the whole point in my mod is so that the system auto-mounts it, which means you get global access. You can edit the vold.fstab with a text editor, if you're on 4.2.1 using my boo image, you don't need to edit it, otherwise just open it up and replace the mount location with a path on your internal storage.

[Q] Transfer FROM Tablet TO USB Drive

Hi guys,
I'm getting tired of not being able to transfer files from my Nexus 7 [rooted] to a USB flash drive. I have Nexus Media Importer software installed, but it will only allow me to transfer files from the FlashDrive to the Tablet but not the other way...it's just plain dumb.
I usually download stuff via torrent to my Tablet and then distribute it to my friends, but when the files are over 4gb, bluetooth is way to slow and forget about the PC option, I don't have any PC to use...so don't tell me to transfer to a PC and then to the flash drive...
Any ideas?
EDIT: Also tried Stick Mount y USB Host Controller :/ NO LUCK!
Perhaps dumb questions, but since you didn't mention these details, everybody who reads your post is forced to guess.
1) Did you check the mount points (in each case) to see whether they were read-write (rw) or read-only (ro) ?
2) Should we assume that the USB stick only has a single partition, and that it is formatted in a FAT32 fashion? Or something else? What device/OS did you use to format the USB key to begin with?
If you are using any file system excepting FATx, the kernel you are using is also important - and you also failed to mention that.
BTW, I have successfully written large-ish files TO a FAT32 USB key on a OTG cable mounted via StickMount with a lightly-rooted stock N7 (essentially a stock ROM and stock kernel). "Large-ish" in this case is about 2.5 GB. (FAT filesystems are not capable of writing individual files larger than 4GB)
cheers

No dumb questions at all, I just started this thread really quick because I am at work and can't be 'on the internet' for too long.
1) I just checked and Nexus Media Importer says 'read only', I haven't seen that :/ (that's dumb)
2) The owner of the USB Stick tells me he formatted it with Windows 7 but never changed the format, it's FAT32 since he bought it. The file I attempt to transfer is 4.1Gb...
About the kernel and ROM, both stock and ROOTED.
The owner of the USB Stick tells me that he recently used it to boot Win7 and install it on a friend's PC and maybe that's why it is on 'read only'. I've checked for the usual 'lock' switch but it doesn't have one...so that must be why. Don't you think?
Also, I could never use StickMount..it just times out attempting to mount :/
EDIT: One more thing, I downloaded 'USB Host Controller' (http://forum.xda-developers.com/showthread.php?t=1468531). I attempted to mount at /mnt/sdext and many other points but none of them worked...I'm using ES file explorer to look for the mount point but it doesn't exist.

Well, the name of the app includes the word "importer". That seems to imply only one direction, but I've never used the app so I don't know.

No matter how you mount a FAT32 filesystem, you will not be able to write a file to it which is greater than 4,294,967,295 bytes in length (2^32 - 1).
Apparently there is something called "exFAT" that is intended for large flash devices, but it seems to be not ready for prime time with Android yet. (Search titles here on XDA for "exFAT"). Also, the Wikipedia page for exFAT says that it is patent-encumbered. That's a deal-breaker for Android I suspect.

The owner of the USB Stick tells me that he recently used it to boot Win7 and install it on a friend's PC and maybe that's why it is on 'read only'.

Hard to say. Re-format it in windows and try again.
Thanks a lot Mr!
I'm gonna use some other app just to try to get it done, with a 'smaller' file. And regarding the USB Stick, let's just leave that behind...I can mount NTFS systems and give my friend the files in a Ext-HDD
Luckily there is always another option
