internal SD Card is sometimes 0 GB? - Galaxy Tab Q&A, Help & Troubleshooting

I have a strange problem. I installed some time ago JB 4.2.1 and everything was fine.
Since a while I have to the problem that my total commander shows the internal sd cards as 0/0GB. When I connect the tab to the PC I see the drive but I can't access the card either. When I disconnect the tab from the PC then sometimes the internal card comes back to be accessable and sometimes the external card shows the problem. After some connect/disconnect tries I managed to make both cards accessable again. But now, a few days later, the internal card is not accessable again.
What could be the problem?

so any solution u people got ............................
Did you try to read the SD card in another place (ie PC) ?
Maybe you must format the card using any of the apps to format or data-recover. This happens sometimes with the cards, so that you must backup them in your computer and reformat them, or the phone will crash.
(That's what is happening me now... and I missed soem data)
no this dose not work

[Q] SOLVED: Connecting with USB shows only internal memorycard...

HI!
I have this problem that when I turn on the file sharing, the computer shows only internal memory card and not the external. Because the phone itself recognizes the external card I have tried to unmount and mount several times without any improvement. I am currently using the latest CM7 nightly, but the problem seemes to have started after I changed the card from 4gb to 16 gb. Any ideas?
EDIT: Erasing sd card from the phones menu helped to solve the problem.
Go Setting>Storage and remount your sd card and try???
I've done that several times....no help... android system accesses the card without problems...music, pics etc.
Did you physically remove your card and reinsert it, or just software remount?
Have you tried the card directly in your computer?
Have a look in windows device manager and see if it reports any problems. (right
click my computer and select manage)
I have tried it all and everything is ok with the sd card itself (I copied recent nightly from the computer on the sd card) also recovery recognizes is... there are also no problems in device manager...
Try to put on debugging mode. And try it with debugging mode on.
If the debugging mode is on try to take it off.

I tried that also and nothing changed.... I have a feeling that it is somehow attached to me using mybackup pro... I restored application apk and data from another phone to this one and It seems that usually the application data should go to internal memory card. In this case it is on external card... so i believe that somehow the programs are still using the card when connected and do not allow phone to share it out... It's just a guess though...
EDIT: so I think the solution is to wipe everything and start all over again
So I fresh installed Rom and wiped everything and the problem still exist... still can see files with file managers in phone and when connected to computer, autorun shows only internal card...
Edit: I tried now 2gb sized sdcard and it works perfectly... the problem is with 16gb card.
Weird. Did you try another USB-port?
I tried different USB-s now and still same I found out that when I connect the phone, under my computer appears two removable disks.... if I turn on the usb connection, only one transforms to usable removable disk (internal) and the other one asks to insert the removable disk. I used the same sd card on my HTC desire with CM nightlies and it worked perfectly... could it be CM-s bug?
Sorry to ask (maby the obvious)
On Your phone.. using your filemanager (Root explorer astro or what-ever..)
Browse to sdcard
Do you have a folder called _externalSD?
On this phone, for some reason the external SD is not mounted under./ but as i said under ./sdcard/ (i.e its mounted under the internal SD card..)
Just a thought
Where the different cards are mounted doesn't make any difference. And as he said, it works with other cards (2GB and 4GB).
CyanogenMOD mounts internal card as /mnt/emmc, and external card as /mnt/sdcard by default.
When turning on USB storage, both cards should be unmounted and shared over USB.
Hi, I had the same problem with mine, and as you said in one of your previous posts, I had to do a format through the phone and as soon as I did that I was good to go.
I did use the same memory card in my old hero so this might have something to do with it... I'm not sure.
By formatting do you mean from the menu Erase SD card? On the desire I actually had the formatting request from the computer, but there was another problem (some of the rom's files were on the sdcards ext or something and I had no access to the card from the USB).... kind of a similar problem if I think back now but after changing to CM, the problem disappeared.
I forgot to mention I am running completely stock rom and unrooted (for the time being) and there is just an option under sd card & phone storage setting to format external sd card
After erasing the sd card from the phone, the computer recognized it i'm currently copying stuff back and i'm pretty sure it does not affect the recognition
I faced the same problem. I had Swapper2 on my NC, and after I uninstalled it (and cleared the data of Swapper2, just in case) everything went to normal back again.
^ a solution.

[Q] Problem with MicroSD - phone can't see it

Hello.
I have a problem.
My SGS(i9000) doesn't see MicroSD(KINGMAX Class 2 16 GB) anymore.... It worked fine for some time. But now when I put it into the slot nothing happens with my telephone. I event don't see any notification about faulty card or etc/
But my PC is able to read/write on the card.
Whatever I tried to do I cant make my phone detect this card.
Could you please advise?

[Q] External SD Card issue: loosing data

I experiencing a very annoying problem with my external SD card.
It seems I am not the only one: http://talk.sonymobile.com/t5/Xperia-Z1-Z1s/Z1-destroy-files-on-SD-card/td-p/418011
Basically I loose random data when I store them on external SD card.
Many random data: let's say about 30-40% of what I stored.
This happens:
* if I copy data from internal memory to external direcly with the phone
* if I copy data from the PC to external card using USB connection while the card is in the phone
* even if I copy data onto the card and THEN insert it into the phone
The SD card is a brand new Samsung Class 10 64GB and I tried also with an old 32GB Sandisk with the same result.
I formatted the card either exFAT or FAT32 and in both cases I can fill it without loosing a single byte with the PC.
I am on .157 stock firmware (only rooted to use Titanium Backup and a few tools) but I had the same problem with .133.
Any possible solution in your expert opionions? It is really frustrating to have only 11GB storage in such a great phone!!!
Got three guesses
It does not correctly unmount the card when connecting the phone to the PC in Mass Storage mode
Kernel Bug. On exFat I would expect that, not on fat32. Can be ruled out if it does not happen with custom roms
Voltage on the SD Card suddently drops for some hardware design reason. Should happen on all ROM's
Sounds like some testing is needed? For example #2 is easy to test when someone with the problem flashes a custom rom with and tests the same sd card again.

SD Card issues

Hi all,
I have a sandisk SD card in my phone set as internal storage since I got it.
Today it is going funny...I can see it in the list of storage but when I browse it I don't see any contents.
I plugged the phone into PC and it shows as 22.8gb free of 119gb but also will not show any contents.
I have removed and reinserted the SD card, I have tried setting it as internal storage again but no luck.
Even in ES File Manager I see the SD card name but once selected no content.
Currently cannot try the SD card in computer directly as I am in office and don't have an Micro to standard SD adaptor card with me. I am not too concerned about data loss as all my photos are backed up on Onedrive and my music on my laptop.
Did anyone else have issues such as this in the past?
Any tips on how to resolve without having to format SD card and copy everything back?
Cheers
Ok, very strange.
In my laptop using card directly everything is there with no issues but phone just sees the 22gb empty part of SD card.
I tried another blank Samsung SD card and it works fine so I copied the data from the card with the issue and everything works fine.
Formatted the card playing up and also is fine.
So no idea why the phone decided not to see all the data on the SD card that was in it for last 6 months.
