Anyone else has this problem on JG3

My Internal Sd card umounts from time to time by itself so i have to mount it again, did start on last firmware i flashed. Anyone else has notice this?

Only time it has done that for me is when I have copied photo's/video's to the internal card and it re-mounts the card to run media scanner.

I haven't had this issue. As the above poster mentions i can see it doign a media scan once i unmounted the internal sd card from a mass storage function when it was connected to my PC

No such problem for me, everything works fine on jg1 with mcr r2

I saw mine doing this Unmount/Remount thing last night, and I'm running stock ROM (too lazy (or scared?)) to do the rooting/flashing jump

No problem with that here...
Have you wiped you device after flashing the rom?

[Q - SOLVED] Memory Unmounted or Unavailable

Hi Guys,
I've got this weird issue with my Xperia T.
When I insert my 32GBSD card, the phone says "Preparing SD card...", and then proceeds as normal. If I got to storage in the settings menu, it recognises the card is present and mounted. I can unmount it and re-mount it.
However, when I try to access the Album/Gallery apps (stock 4.0.4, stock 4.1.2, CM10, AOSP 4.1) it says "Memory unmounted or unavailable" or "Insert SD card". I don't get this as I can access the card with file manager apps, as well as on my PC. I've tried another SD card and the same thing happens.
It happens in any ROM I test. Manually rescanning the media will pick up my music in the Walkman app, and will load the images in Album, but the "Insert SD card" messages still appear.
Do you guys have any idea as to what's going on?
***EDIT***
What's interesting to note is that when I restore a NANDroid backup (which restores my latest CM10 installation), the phone boots up fine and recognises the SD card fine, and even updates in Walkman, etc. when I upload new songs through the USB cable. However, as soon as I remove the card, I'll get the same symptoms.

Please search.
Make a backup if your sd card and then clear it in settings. It is a known issue when changing from cm to other roms

I did search. I formatted and wiped my SD card many times, to no avail.
Not sure what I did, but it now works since clearing Dalvik Cache, Cache, System and Internal SD data.
Thanks anyway.

Have you tried reflashing the current Rom you're on or try flashing back to stock?

Yes, I tried

Xperia T or TL users may have experience this. Their phones are known to kill SD Cards. Try connecting your SD Card without your phone.

hi dani
my XV has this kind of problem and my partner also have same problem too, XV have killed your SD card and your SD card may not able to be read in ur PC too, either u need to exchange a new SD card (of course change with under warranty) or go without using SD card. i have no idea why it can happen, 1st SD u use in XV may have this kind of problem, 2nd SD (new) inserted to XV will go fine.
(not sure whether it is a bugs or not)

I had a corrupt sd card in my V. I put it in the PC, it asked me if I wanted to format it and I said no.
Then I ran chkdsk -F on it, and it fixed everything and saved all my files.

hmm, mine 1 totally not able read the corrupted sd card, so change under warranty

Maybe my issue was slightly different. On my V, the message was "Damaged Sd card" and it would not mount on the phone.
On the computer, when I plugged in the Sd card and tried to navigate to the drive, the computer would only prompt me to format it. I couldn't view any files.
But I could say "no" to the prompt, open command prompt, and from c: run chkdsk on the sd drive.

my sdcard now completly unreadeable , both from PC and phone ...

[Q] SD card issues with new kitkat builds

Hi,
I have been using both stock, CM builds and other after market roms from my xperia x10 mini pro days. Now, I own an xperia mini pro and xperia z. I have installed various kitkat aftermarket roms on my xperia z. I installed the latest cm11, From here I could not change any contents on my SD card. Within the phone I cannot copy to or delete from the sd card. I tried all file managers including the ones with root permissions. I removed the sd card and tried direct copying. The fun is copying will be succesful. But once I unmount and remount the card, the contets wouldnt have changed. I try to format the card. It will get formatted but once I unmount and remount all the previous contents are intact. I the flashed back 4.3. There again the issue persisted.
I had the same issue with my xperia mini pro and cm11. Since then this is my second sd card(32 gb on mini pro and 64 gb on xperia z). I know there are certain issues with kitkat and sd cards. Can anybody please throw some light on resolving this issue. I am a rom hopper and I dont like to be cornered with these issues.
But strangely, I never had any issues with pabx's build.

You should ask in that specific thread of the rom you're using instead of here.

I think this is a generic issue
I think this is a generic issue. It eminates from the point that the majority of the after market roms are using bits from the CM project, Thanx for the reply. What I want to know here is does kitkat do anything to the sd card which cannot be washed away after even attempting a format?

Did you try to format the sd card with your pc? Does the pc even recognize it correctly?

If you have problems while on a stock rom, then I suggest that you backup your data, then format the SD card with the SD Association tool - https://www.sdcard.org/downloads/formatter_4/
If possible, you should do this via a card reader/slot and not while it's in the phone.
If you still have problems, then your card may be faulty.

Yes, the format was tried on pc
The format operation was tried both on windows and Arch Gnu/Linux. I can add or delete a file. But after remount, the changes are gone. It is like I am having a write once DVD.

sorry for resurrecting this thread but has anyone found a way to fix the issue?
Just like the others, I encountered the problem after I downgraded from Kitkat to Jellybean. I have tried formatting my 64Gb Transcend micro SD card using various softwares. Some fail to format midway. Some indicate that it has been successfully formatted but upon checking, the contents are not removed.

Due to a policy change in Kitkat it is, for most apps, not allowed to change the content on the SD card. To fix this, root the device and install de SDFix from the play store.

Do I have to root it using Jellybean or Kitkat?
