I noticed that whenever I modified the file system with Astro, it doesnt actually change anything on the sd card. Similarly, whenever I modify the sd card using the usb link the changes dont show up in astro. Im using the latest mattc Android build.
Anyone know what's wrong?
i noticed too lol
I just tried it with other file managers too with the same results. This is definatly not ok. Does anyone have a solution?
Root Explorer. Just now used it to change my boot animation. Word.
I was just about to ask something similar...
Basically, A LOT of it comes down to the Android system doing a "rescan" on the SDcard in order to organize the changes (new files, changed files, etc). This is especially true if you use a USB connection to copy new files (movies, .mp3s, etc) to your sdcard (mount as a disk drive) from something like Windows.
There are apps out there that will rescan your card, but they don't appear to work with the way that we have Android set up on the sdcard.
Other than doing a reboot, has anyone been successful in doing a rescan of the sdcard while inside of Android in order to update the changes?

I have found that when I USB (PC to HD2 (Android), i copy a file from my PC to SD Card while in Android OS, I can see the file on my SD Card with size. However, when I disconnect from USB I cannot install that file (APK) on my HD2. So, I use WM wherever I copy file directly from PC to HD2.
Anyone have any suggestions?
I tried all the file explorers I I think the Root Explorer is the best as it shows all files and has the best/easiest options.

You can either remount the SD card in the settings menu or use the Dev Tools app and tap Media scanner/locater.

Remount doesn't appear to make it work (you'd think that it would, but negative).
I'll try the Media Scanner trick (although I have tried others, maybe this one will work).
Are you able to confirm that this works?
can someone explain the media scanner trick? I dont know what that means..
If you have a ROM with Dev Tools installed (you can also get the APK but this force closes for some.) you can use the Media Scanner item to recreate the cached list of media files on your SD card.
Good luck.
Just got my Iconnia last week and it's stunning.
However if I drag .apk's onto my 32Gb SD Card I can't seem to find them using Linda File manager.
Is there a particular programme I need to use to access it?
When I look into Storage it only seems to show my internal memory, howevermy Gallery DOES find my camera pics on the card so what am I doing wrong?
Dragging using what ?? on desktop PC ?? ( best is to copy & paste )
for when on the iconia... I downloaded "Astro file manager" ... there are many others...etc
your Ext_SDCard and USB storage is under the sub directory of /mnt
You should post in the "General" section...as this is the "DEV" section...
File Manager for Honeycomb.
I ran into this problem when I first got mine too.
The external sd card is actually showing in mnt/external_sd in your root folder
Basically this means that when you use astro file manager or root explorer and you open that instead of clicking on sdcard you click the folder listed as "mnt" then external sd
Thanks Guys.
Mods - Can you please move this to general Doh!
Hi,
Just Got the 7.7 3g - so far so good. Screen is as good as they say
The extra resolution defn. helps with web browsing.
Not finding any lag really.
7.7 is just about the limit for my two handed use but i would say the original 7" was a wee bit easier to handle but something with time should become more intuitive.
Just a few issues - external sd card is somewhat limited. Might be deliberate by Samsung but does not make sense.
Normal user apps cant access to the external sdcard. Using connect bot, i checked permissions and it seems that it is mounted by the os with system permissions, where as the internal sdcard is mounted as sd_rw.
This can't be correct? The only way to copy stuff to it is to use the samsung system file explorer as it has system permissions So copy to internal first then to external - this sounds like a bug?
I have not rooted this yet - might then chown to sd_rw get rid of this ?? There is a lot of entries in the vold.fstab to make sense of. Not a hacker so just looking around. A bit too early to start soft-bricking
But I take these don't have protected bootloaders so thats why we can root ?
Video playback is v.good but I am not able to throw on a bluray m2ts file (obviously with the sd card issue) and play smoothly. I found Dice player can handle m2ts by renaming it to a ts file. It then can use hardware decoding. Still drops frames but still watchable to a certain degree. For all other files mx player is still best. I have lossy transcoded some "native" blurays clips and seems that it handle high profile h264 1080p at high bitrates very well. Hoping, formatting sd card ext3/ext4 will improve things.
On the whole very impressive device - plus more ics goodies to come soon hopefully.
I've noticed some issues with the external SD card as well. Only the stock file manager can copy files from the internal storage to the external storage. I was able to transfer files to the ext. SD via Dooblou's Wifi Explorer, though. Although that would crap out a few times.
I'm hoping that we see some new ROMs with a different file system at any rate. The 4GB limit is so 1998.
Fix for external sd write issue
I've already posted a fix for this in our original thread?

There is a fix for the write to external storage in this thread:
Samsung Galaxy Tab Plus->Galaxy Tab Plus General->unable to write files to external sd card
post #7
Requires root to apply fix.
There is a new permission that older file managers aren't asking for yet. The stock file manager knows to ask for it.
Fix worked for my P6810 wifi.

Simple solution for external sdcard write access on Android 3.2...if you're rooted
I've found a simple solution for gaining write access to the external sdcard (/mnt/sdcard2) on Android 3.2. The sdcard is mounted r/w, but the owning group is media_rw which is linked to the WRITE_MEDIA_STORAGE permission. Unfortunately, this permission was not required for access to the external sdcard prior to 3.2 so most file management utilities do not request it when they run...meaning they only have read access to the card.
The simple solution, if you're rooted, is as follows:
1. Using a root-enabled file manager, navigate to /system/etc/permissions and make sure you have mounted the file system r/w.
2. Edit platform.xml and find the WRITE_EXTERNAL_STORAGE permission.
3. Add an additional group definition for this permission...<group gid="media_rw" />
4. Save the changes to the file.
5. Restart your tablet.
After this change, any apps that request the WRITE_EXTERNAL_STORAGE permission (which includes almost anything that access either of the sdcards) will gain group membership in both sdcard_rw AND media_rw, giving them r/w access to both sdcard filesystems.

Rooted and then applied this change.
Can write to ext sdcard !!!!
Cheers
Will apply as soon as i get tad, should be getting it today, cant wait

I think you have to format the sd card in the tab. I been able to transfer files no problem. Maybe its due to the mtp for the internal sd.

Using downloaded apps or the stock File Manager app? Because I formatted the SD card in the Tab and nothing else can write to it. Now, I can drag and drop stuff from my computer via MTP, but that's not the same issue.
Ok, I'm trying to add the permission and it doesn't seem to save after a reboot. I'm rooted and made sure to mount that directory as R/W. After I edit platform.xml and reboot it simply reverts. Can anyone offer a more granular description to this n00b?
Thanks.
Edit: Nevermind. I edited the file on my computer and copied it over the original and am good to go.

Thanks Burhanistan. I had this problem too and did what you did to get around it. Now I can read/write to the external SD with any file explorer.
Hello,
I can access the external SD with no problem, only issue is Titanium backup showing 440Mb capacity on the external SD (32Gb card).
Anyone with the same issue? Any fix?
Thanks.
No problem for me

Things must have changed as i got my P6800 recently did the upgrade from samsung and tried to copy to external sd and no problem for me. I never tried to do it pre upgrade but maybe the upgrade fixed that. Re i can copy and paste to device from my pc when its connected - to both device and sd. I can also copy using the the stock file manager from device to sd card.
No Issues here also
I recieved the tap a week ago. Now my 32GB Sandisk SD is here.
The Tap did at the first startup and using the described 12 MB Android update via internet conn.
Until now there is no issue between writing from/to SD over PC/MTP, copying between internal and external SD. Used preinstalled Filemanager and ES File Ex.
I tried it unrooted and rooted but not before the Android update.

Some people are reporting the above procedure is no more needed, however, with several apps (like Titanium backup, and a SAMBA explorer), writing to the sdcard (extstorage/.../sdcard) is still impossible (GT6800 updated to latest samsung firmware).
I have used this procedure and can state that Titanium backup works now with the SD card.
Thanks to many reading within the XDA forum, I have found this simpler procedure :
- download / install the "Root Browser Lite" app from the android market
- add write access to group and other to the following directory: /system, /system/etc, /system/etc/permissions (with root browser Lite, press on the directory name during 3 seconds to get a contextual menu allowing to change the permissions)
- add write access to group and other to the file platform.xml in /system/etc/permissions
- use the editor of "Root Browser Lite" to modify the file platform.xml as described above (you should have two <group gid= ...> lines within the WRITE_EXTERNAL_STORAGE xml block.)
- save the file. Verify that a .bak file has been created and that the date of platform.xml changed.
- remove the write access.
- Turn off the GTAB, then turn it ON.
NB: Titanium backup still reports a erronous free size on the SD card (401MB), but backups on the sdcard work.

Hi, I edit the file but when I try to save it I fail because it says original saved as .....xlm.bak, but I can't find that file and the one I find is unchanged, any ideas?
There is an automated installer for the fix here:
http://forum.xda-developers.com/showthread.php?p=21670802
Is for the plus but worked fine for me
Sent from my SCH-I815 using Tapatalk
damm, must forget something, just followed exacty all the steps
still no writing on sd card
the automatic installer failed also
IS there a way to go into the (forgive the incorrect term) "registry" or similar, and have Android re-interpret/understand that instead of looking in "/sdcard"... it should instead look/point programs to "/mnt/sdcard/extstorages/sdcard"...
i heard that it might be called something like a "simlink" or "symbolic link"... maybe this could resolve the application installation issue to the sdcard as well as backups, transfers, etc... right now, not only do i run out of space too fast, can't install apps to the sd card, but as well, if i should run a hard reset... all my data erases! (yes, the internal "SD card" is erased in a hard reset)...
so, for all practical senses, when it says it will erase data, unless you KNOW you have copied ALL you user data to your "Real" SD Card, you will kill your data without even knowing it when you do a hard reset, even if you "thought" you were protected because "I saved my info to the SD card!"
(and yes, this was my experience today, so it's a fact.)
backup programs won't point to the sd card, (app manager, titanium, app list backup, etc)...
so unless you actively move files individually to the card (and know where to look)...
Bottom line... is there a hack/workaround on this that's not just "open up for file transfers" or is someone working on a ROM that might kill the partitioning and allow the /sdcard to actually point to a real external card?

hi forum
i would like to use the EzyKernel v1 - 23/02/2012 as in post http://forum.xda-developers.com/showthread.php?t=1513413&highlight=ezykernel
one of the prerequisites is a stock ZSKL firmware.
on the tab is/was XXKL4 AUT/CH
i successfully flashed the ZSKL2 - but that's where the nightmare started: i could not write to sdcard, busybox/superuser don't work properly, as i can't get root via su - which means to me, that there are messed up accessrights also in other places, not just the SD. the funny thing is, that i finally got the overclocking EzyKernel working, but not busybox + superuser.
does that sound familiar to anyone ?
i would really appreciate any ideas about this.
thank you
with best regards from switzerland

could you please explain what "make sure you have mounted the file system r/w" means. And sorry for my noob question, but does this fix allow to install apps on the external sd card or I'm missing something.
So here is my situation...
I would like one flash one of the new ICS roms and have run into an annoying problem.
I created a directory on the SD card called "Root", and downloaded the rom and placed it in the directory. I then rebooted into Recovery and after selecting update from zip on SD card, the file can't be located.
The only file in the Root directory is the first ROM I flashed and gaaps.
I can't seem to locate those files from Es file manager though.. Thoughts??

From recovery your sd card is called SD CARD.
from within say file manager your sd card will be in mnt/external_sdcard.
Some sd cards has a issue being read by cwm recovery. Often formatting the card in a Android phone or with sd format app. if k downloaded the rom file from within windows . In android file manager long tap on the file and click properties . check to see if the file is names xxxx.zip.zip
if you have stock recovery . the file must be on the root of the external sd card NOT in a folder at all. But your message makes me think you have cwm installed . if you are sure none of the above is the issue. Try re download the rom of your choice and try again.
Good Luck

Erica is right. When you copy your file to EXT SD Card, you should copy it straight to the card. NOT put it in some folder. This will make it easy for your Recovery to find.
This is the basic method. Depending on which recovery you use (RA or CWM) there are other locations you can use as well (USB Drive, Internal memory) but best to get familiar with the basic method first.
This worked for me... Thanks.

Recently, I have an issue when I want to delete or move files from my ext sdcard. It mentions "unable to modify contents of the sdcard. This is caused by new external storage ploicy introduced by Google in Android 4.4. To bypass this limitation you need to use one of "sd fix" tools available in Google Play. You need to be rooted, though."
So I try the application, I tried to change the kernel but it's not successing.
Does anyone have an idea?
Just use your system file explorer rather than external app
