Orbit2 corrupted SD card once again

Hi everyone!
I have an annoying problem with my orbit2 and its sd-card: every now and then the orbit corrupts the card so that the explorer does no longer list any files or directories. the files seem to be still present though as the memory manager claims the space still occupied. looks like the FAT is smashed somehow.
this happend with the standard 1gb card several weeks ago and now again with my new 4gb card as well. the problem this time is a) i want to get the data back and b) ensure this won't happen again.
i cant access the card by one of my two cardreaders, they get both stuck when the card is inserted.
i already googled around for some hours and of course tried to find a problem description in here but didnt find satisfying results ;-(
any of you got some information and suggestions 'bout this problem?
thx already

Same problem here, does not register in any card readers either, most annoying!

format the SD card before use. it will solve the issuehttp://forum.xda-developers.com/images/smilies/wink.gif

solve the issue of not being detected by the card reader maybe ...
but what about the data loss on the xda? there is not even a write protection switch for a microSD card

My orbit 2 hasn't currupted my 4gb MicroSD card. I formatted it into FAT32 before I put it in my phone, so that might be why. Doesn't FAT have a limit of 3.5gb or sommat, where as FAT32 is much more.

hmm guess you are right but mine is already fat32 formatted
i never did this by hand so it was already like this when i bought it......

yep.... me too. After four weeks, my sd card shows folders with squares in the name fields... can't open them and lost a bunch of photos and videos, not to mention the applications that were installed in there as well...
4GB ScanDisk micro SD card

Must be some software on the device causing that, can't think it's a problem with the SD card

hmm hmm hmm ... was not using a programm shortly before the problem ocurred. i have a SanDisk card as well btw but as said in the first post the problem ocurred once with the 1gig card as well ...
i will try to get a cardreader that can deal with sdhc cards and then try to check the card again .....

I have considered that possibility... or maybe some particular configuration of one of the programs installed.
But I haven't changed anything in about four days... then only today the problem occurred. Only thing unusual I did today was take a bunch of photos and shoot some 4 or five 1 minute videos... could it be a problem related to CorePlayer/Camera/Video recording??
When I got back and synched it, the sd card was messed up... but I still could read my photos through the phone... then after a soft reset, the phone was not able to read my sd card anymore...

coreplayer is installed on my device as well but i don't think its related to it (just a feeling though)
the more interesting point is that you tool some photos .... i'm not totally sure but i've taken some pictures recently before the crash as well and they get saved to the storage card on my device ....
i will switch the save location back to main memory now for testing purposes and wait some weeks if theres no better idea

Hi,
I had the same problem with my 8GB SanDisk card every two or three days until recently. Two things changed:
1. flashed bepe's WM6.1 image
2. didn't install MortPlayer yet which I had running before
Now everything seems to be working fine. No problems for a week now.
I thought maybe there's a bug in WM6.0.

hmm i don't wanna install an unofficial WM update or ROM on my cellphone ... no problem doin' stuff like this on my pc or satellite receiver but my cell is kept clean
hope there will be a regular update then soon ....

...my experiences:
I had several crushes of the SD card, where I have lost almost all of the content. First lesson:
Backup/Sync SD with my PC regularly, so this is more a time issue now
Second:
I have discovered, that the loss happens (at least valid for me) when:
- device wake up from standby by pressing power button
and
- a program is running, which accesses data on SD card, like MP3 player, ebook reader or Navigation. All of them sores data on SD card.
Possibly a bug in the card handling part of code, where data/buffer is being written falsly, during wake up of the SDdevice.....
Can somebody proof that?
Regards
Dejan

I have never had a SD card corrupt on me.......My TC is as it came out of the box.....I have installed;
- AstroNavigator II
- Fun Contacts
- SMS Notifier
- PZP
I hope this helps..........
Will

I also encountered the first problem of this kind today:
Although I can still take photos on the card and they claim to be stored in /DCIM/100MEDIA/IMAGxxxx.JPG, the DCIM is shown totally empty when trying to access it via Explorer.
When I try to open the DCIM Directory with the tool Total Commander, the tool shows up an "Error 13 at directory change".
Does this mean my card is defect now? All the other directories seem to be okay. It is the original card I got with the XDA with TomTom installed on it. So I guess I might take it back to my provider.

Michael

I have the same card.
Even the same problem for a few times. For me a soft reset solved the problems. I had no data loss. So I would assume that it's a problem of the phone not being able to read the card properly for some reason.

Same here
I have an 8GB SD card and some of my folders vanished while some remained. All the files in the root are gone.
I used an SDHC reader to check on my PC and it cannot see the missing folder either.
Any suggestions for a good freeware MicroSD data recovery?
I guess the theory of the phone going standby while an app is writing to a buffer in the card is causing the big mess is right...
Cheers,
-Feaps

My two pen'orth -
Is this isolated or a major problem?
>I guess the theory of the phone going standby while an app is writing to a buffer in the card is causing the big mess is right...
If windows is using write back cacheing and the device switches off with the file data in the cache then maybe the card FAT is being corrupted
the artemis had this same problem, have a look in the sticky at the top of the artemis threads for the fix (it's worth reading), maybe it will work for the polaris, luckily I don't have one yet so I can't try it myself.

thought I lost all in my memory card (sandisk 6Gb) . That happened after reinserting the card in the cruise .
I found with the explorer that my card was empty ....but , I found also a card number 2 .
During the time when my card was out the Cruise , I used probably a program who needed a storage card . So I think (but maybe I'm totally wrong) that WM6 created a virtual card within the PocketPC .
So when I put my Sandisk back , A (virtual) storage card was already in the PocketPC . So my Sandisk has been renamed Card 2 .
I removed the Sandisk , deleted the Storage card (empty) with the explorer , and reinserted my Sandisk again .
Everything is OK .
In fact , nothing disappeared .

MicroSD HC: Did your files disappear?

It happened to me 3 times in 3 days. The entire contents disappeared with no reason. I have never experienced this issue, but it is getting me out of my nerves.
My SD card is a Sandisk 8 GB SDHC.
I have scanned the card using a card reader and it seems that all the files are there, but they're unlinked. The space is used, but the files are not accesible, so when I go to Storage Card, I find it empty.
It's TOTALLY annoying. Please, give your experience if you have this problem.
Have you lost all your MicroSD card contents and you don't know why?

My Sandisk 8gb card came with a USB2 card reader that is great speed-wise; but twice I lost all the data when using it. I didn't realize it might be related at the time, but then I misplaced the reader and switched to using the adapter kind -- the SD sized thing that you slip the microSD card into (my laptop has a SD card slot). It's been a few months now, and with constant switching of the card between my Touch, Touch Cruise and laptop, I've not lost the data since.
While I can't say for sure it's related, it hasn't happened since I stopped using the USB adapter that shipped with the card.

I think it's not related to the use of the adapter since the first time I lost my files I was on a route using Tomtom 7. In my way back, I had to go without the navigator :S No maps, and the videos and pictures that I took, totally lost.
Fortunately I have an application that is pure gold to recover every disaster that could happen (recovers partitions even after formatting the disk, and files with their original names). It's not pleasant for me to use this application ("[email protected] Partition Recovery Enterprise"), but this is becoming too usual...
By the way I'm using udK's WM6.1 ROM R6, even though I don't think it's related to it.
My MicroSD is formatted in FAT32 with 32KB clusters.
Any ideas about how to fix this problem?
The last time I lost the contents I was about to sync music with WMP (with the USB connected).

Good luck... I'm using the ROM that shipped with the device. Guess the only way to know if it's related to a cooked-ROM is to re-install the official ROM and see how things go.

I'm using HTC original ROM and 8Gb Sandisk card with no problem for more than 3 months. My fingers are crossed

I'm using HTC original ROM and 8Gb Sandisk card with some issues (http://forum.xda-developers.com/showthread.php?t=407046&highlight=bodisson), but no files are missing.

Sometimes I get extra file names with really weird characters. Usually, if I reinsert the card, these go away and I can access normally the card.

that happened to me twice..my problem was solved by installing an sd enhancement cab file. almost everything appeared back in my sd.
i have an HTC touch cruise. here is a link for the cab file..try it if you want, maybe you ll solve your problem
http://www.sendspace.com/file/kr98xz

did you use something like sktools for change pathes of temp/cookes files of I.E or so on?
If yes it could following happend:
You change the destination path for some application like InternetExplorers Temp and Cookies pathes to point to Storage Card.
After this you removed the card on any time.
The device cannot find the path to the Storage Card and creates a folder "Storage Card" on the root of the internal device memory.
If you insert a card again, it show you onliy the content of the new folder.

Dudes,
I'm bought a sandisk 8gb micro SDHC about a month ago.
Filled it almost to the brim with music and podcasts.
I regularly uses great programs like S2P and BeyondPod for music and podcasts to listen with my Bluetooth A2DP headset.
Had no problem until recently where the entire card is not readable anymore
Symptoms:
1) the phone started not to recognise the SDHC, where it could not detect any inserted card
2) the failures on the SDHC gave me corrupted files. I was able to repaired these by using the Windows XP chkdsk and fix error command
3) by the 3rd time i did this, the card was not readable at all
Suspects:
1) every time polaris hang, i would press the reset button. I suspect tat this would corrupt some files (possibly even the entire SDHC ??)
2) every time polaris hang, i think the phone was running more than 1 app at the same time. In my case, it was probably S2U2 and S2P or BeyondPod, together with BT A2DP.
Don't think it was caused by these great apps, but rather the way Polaris or WindowsPPC handles multi tasking
Will be returning the 8gb SDHC soon for a replacement.
Any ideas on how to prevent this from happening again ?
(other than not running multiple apps at the same time)
Thx
BTW, i'm running windows 6.0, the original HTC polaris rom

Also have a Scandisk 8gb card in my Polaris...
Problems im suffering is that now and then the storage card looses connection.... I can not see it on my mobile and also its not showing up using ActiveSync.
It happens really often and mostly when im using software that depends on it like IGO. The application crashes because it can not access the files needed.
Ive read somewhere that this only happens with scandisk cards so im considering buying a kingston card.. can anyone verify this??

Well the best thing is to make sure, you safely remove your hardware before removing the sd card from the pc or otherwise change the device settings of the memory card to "optimize for quick removal" in the device manager

I recently switched from a non-sdhc card (1 GB) to a SDHC 4GB kingston.
weirdest of all things is that i lose certain applications, but not all!
For instance i have TomTOm installed. Stopped functioning and lost the icon. But SK Tools still works. :S
I'm not very happy with this, since i use my phone ALOT with TomTom and all the other apps i installed on it. Especially at work.
Gonna try the artemis sd fix... Hope it works.

Could it be that you'd made a rom-upgrade with the sd-card in the phone? I had the same problem - lost files on sd-card - with the original 1GB-Card and a new 4-GB-SDHC. I think (and hope) that leaving the card while upgrading has reasoned this issue. After reformating the card in the pda the problem has gone for me . Thank you for your answers...

Yes, i actually did leave the card while upgrading. But i didn't lose any data until a few days AFTER the upgrade. And i frequently soft-reset the device.
I solved my problem (i think) by deleting 'program files' on the storage card and making a new 'program files' folder. It works for a few day now. (keeps fingers crossed)

I did a ROM upgrade (udK Diamond R7) without the microSDHC card, and yesterday night I lost all my files for the nth time.
The space remains used. I was listening to a podcast (that was stored into the card), and suddenly, when I ran the File Explorer to do something, all the files were missing. The podcast played correctly, but when I tried to re-open it, the file could not be found.
I'm feed up with this problem. It is like having no card at all...
Please, we need somebody to fix it. Is it happening to other brands of only Sandisk?
Thanks.

I simply turned my phone off. Then back on again and storage card had turned into storage card 2. Everything I had on the card was lost. So I carried on using the card and now its storage card 3 and the data from when it was called card 2 is now lost.
copilot often asks me to insert map data.
Ive found that if I remove the card and close all programs before I turn the phone off I dont lose data.
O2 told me to send it in for replacement. That was months ago. Not had chance yet. Might be too late!?

udk's r7 must be faulty, i lost my destinator files 2 times and dawg i didnt took a backup for quite some time. no favorites for me now :<

Do you mean that the problem might be the cooked ROM? Maybe we can isolate the problem with this approach.

[Resolved] [Q] Is my SD card defective or do I have a different problem?

EDIT: Answer at bottom, but my OLD card turned out to be the defective one.
I just upgraded from a Sprint Samsung Epic 4G to a Sprint Samsung S4. My S4 is already rooted and has TWRP.
To go with my new phone, I bought a Patriot Micro Mobility 64GB Micro SDXC card. The card is class 10 UHS-I and is obviously formatted exFAT. The first thing I did is format it in the phone (which curiously gave me a little bit more free space), unmount it properly, insert it in the little USB reader it came with, and then use Win7 to copy the full contents of my old SD card onto this one. The next thing I did, from cygwin, is a full "diff -rl" between the old and new card.
To my surprise a single file differs, from a single nandroid backup instance: clockworkmod/backup/2013-06-02.21.44.05/system.yaffs2.img If I do a cygwin "cmp --verbose" I see what looks like 1-bit differences, always about 240MB into this 251MB file.
If I rename that file on the SDXC card and copy it again and immediately "cmp" it, it compares fine. If I then do a full diff again, the file "changes" and is now different -- with a different number of differences from the renamed first copy. (Yes, those two files differ from each other on the SDXC card.) I can do this as many times as I want, getting the same behavior each time. Once I get differences, it doesn't seem to change again after that. My guess is that it is corrupted on copy but when I do the first "cmp" I'm not reading from flash but reading from the Windows file system cache. And that the full diff effectively flushes that cache so I see what is really on the flash.
EDIT: After much painful investigation, I discovered that it's not the new 64GB SDXC card that's defective. It's the old 32GB SD card that is defective. Only one file gets corrupted when copied off of it. I took the new SDXC card out of the picture by copying the one bad file to my hard disk, then unmounting the SD card, then remounting, then again copying to my hard disk (different filename), then repeating. I get different file contents every time I do this. This happens even with different USB readers.
I've never heard of such a thing, but this card is two years old. Looks like I need to make one last nandroid backup of my old phone, since this one gets corrupted when copied off the SD card!
If anyone has seen anything like this before, I'm still interested in hearing about it.

Undiscussed micro sd card issue.

I'm stumped with this one...
Got a brand new SanDisk 16gb sdhc card. Card mounts, reads, and writes fine for all actions including TWRP (no need to reformat sdhc cards to fat32). The issue is that titanium writes the backup to it, but cannot restore from it. What happens is after selecting my batch restore option, ti begins the process of restoring, but then fails do to a status bar message that pops up saying "unmounting sd card". As soon as I close titanium, the card remounts and the normal "preparing sd card" message is posted. This only happens with ti. File transfers, photos, nandroids, etc all work. I have the exact same card in 32gb which works fine with ti.
I also tried reformatting the card to fat32, re-ran ti... same issue when trying to restore. Only way to restore my ti backup was to move the ti folder to my internal, which worked fine, including moving the entire 1.5gb folder.
At a loss here, never experienced or been able to find anything about this issue. Any thoughts before I try to get it replaced?

If you swap to the 32GB and the problem goes away that tells you the 16GB is bad for whatever reason.
If you really want to diagnose it, try putting the 16GB in, running a backup, then transferring those files to the 32GB.
Then, transfer the backup files, either via your PC or 16GB-internal-32GB. Now try a restore from the 32GB. If it works, you know the 16GB is bad.
I've had weird issues with SD cards and my S3. Went through 2-3 64GB cards and always thought it was an exFAT issue but couldn't ever figure out exactly what the issue was. I know for sure trying to format in the phone was garbage though, always caused issues and freezing. Always format in your PC as FAT32 or exFAT then put it in the phone.

Definitely want to know what the issue is. Good suggestion, only issue I left out of the op is that my same version 32gb card is in my old S3 that some heartless f**k has! This 16gb card is my economical replacement for my replacement S3. But your right, that would definitely prove whether or not the card is defective.

[Q] Anyone else having issues with corrupted microsd cards?

I've tried 2 different Sandisk Ultra 64GB microsd's...the first I formatted inside the phone.....the 2nd I took straight out of the packaging and put into the phone..in both cases after a random amount of time I found the microsd corrupted. In the most recent case I tried putting some books onto the card via adb push only to have it inform me that the sdcard was a "read only filesystem"....I then went into es file explorer and tried to browse the card...the "Android" folder was still readable but all other folders now appeared to be some type of file because when I clicked on them it popped up a panel asking me to tell it what sort of file it was....text, video...etc.....after rebooting the phone it would not even mount the sdcard.....I've taken it out and put it on my laptop to run an fsck (linux version of chkdsk) on it and it's finding all sorts of issues:
/Android/data/com.sand.airdroid/********.***

As much as I have loved the phone if it's going to continuously lose data I'm going to have to send it back. The first microsd came out of my old phone and had worked fine in it....to avoid issues I let the phone format it....sandisk is THE name when it come to sd cards in my opinion so I have a hard time believing it's any sort of quality control issue...especially since I tried two different cards...the 2nd one being brand new out of the packaging. Comments appreciated.

I am using a Samsung microSDXC 64GB card.
I formatted it on my PC before using it.
So far, I haven't had any problems.
Loaded pictures, ringtones and a number of apk's to install.

Format the SD card on your pc and format to fat32 instead of exfat. Use the instructions from this link.

While I'm willing to try it I would think formatting it on the PHONE would ensure it was in the format it needs to be.....however linux by default uses the fat32 (or fat 16/fat12 depending on size of media) filesystem when fat is chosen. It doesn't have support for exfat. I'm going to try picking up a cheap 32gb from PNY or some other manufacturer than sandisk and see how it behaves.
Thanks for the replies!

Do you ever use adb to push files to the phone? It seems whenever the corruption is noticed I have either just put some file on...am in the process of putting files on or just put some on recently via adb push <filename> /storage/sdcard1/<folder> If not what most common method do you use to get files from your pc to your phone storage?

I just plug it in , and Windows 7 mounts it as Portable Media Player - and from that point on, just copy to, or delete from, the folders. Works for both internal storage, and the micro SD. So far no issues. I have a cheap and slow 32 GB card .

Sandisk 32GB class 10 user here with no issues. I did have some issues when I connected my phone to the computer through a non-OEM USB cord though...

Sent from my 6045I

My experience was great until last night. I don't know what happened but I downloaded a new app (Cloud Player by doubleTwist) and as it's nearing the end of reading the music on my SD card (a SanDisk Ultra microSDXC 64 GB), it suddenly stops recognizing the files to the point where the phone was no longer reading the SD card at all. I've tried remounting the SD card but to no avail (even after a factory reset). Interestingly enough, I /was/ able to mount it on my old phone (Note 3) and it worked without a hitch, the card wasn't formatted or anything of the sort and the data was perfectly intact. I tried mounting another SD card I had lying around on the Idol 3 and it worked just fine too. So, what the heck? I sent an email to doubleTwist considering that the evidence points towards the problem being a combination of the phone and the app but I'm at a loss here 'cause I don't see how I'm gonna get the Idol 3 to mount my SD card, even if the app is fixed. Maybe get a replacement from Amazon? I'd prefer to avoid that seeing as how my model hasn't been plagued by the issues detailed on this forum (aside from the buggy Tap to Wake function that is).

Yeah I noticed the corruption only seemed to occur when pushing files to the phone via adb. I'm on linux so it doesn't just mount as an mtp device...I've gone to using other methods to transfer files such as airdroid etc and so far the issue has not occurred again.,

Samsung EVO 64GB corrupted
I had a Samsung Evo 64gb for two weeks everything was fine then one day it changed to a RAW format and I couldn't use it. I have tried everything and don't know what to do.

Hi,
Im having some similar issues with my Idol 3 and the SD cards. First I have a 32gb card that was corrupting all new files stored in it... I formated with the phone, and still the problem continues. So I bought a new 128gb (a PNY) on amazon, making sure specs were compatible, and now it keeps unmounting the SD card couple of minutes after reboot or installed.
So far I have tried:
Format the MicroSD in the phone
Format the microsd in the computer (with partition formats Fat32, ext2, ext4)
make the microsd card with several smaller partitions, down even to 32Gb.
restore phone settings.
factory restore the phone.
Test the MicroSD card in several devices (all worked fine).
Even went to cricket wireless and tried the Micro SD card in another alcatel Idol 3 (worked fine there).
So far, nothing seems to make the idol keep the MicroSD working. It just says "SD card unexpectedly removed".
Any suggestions? Could it be the SD card or the Idol 3?
Thanks.

Sadly the answer is "yes"....cause it's more a combination of the two.....I have a samsung 128gb in my idol3 and it runs fine...a 64gb adata also ran fine....a 64gb sandisk repeatedly failed as yours does...and now has failed on a 2nd device so that card is physically bad in some way. You'll basically have to find one the idol3 likes...when in doubt use the brands others have indicated worked for them...I don't recall PNY being listed by someone as "worked for months without issue". I can vouch for Adata and Samsung. An important point to consider is it MIGHT work initially on that idol3 in the store...but more importantly would it still be working 1 month later.....6 months later...etc

I have a 64gb Samsung that corrupted last week after working fine for 4 months. It happened while writing to the SD card. Wife was talking and all of a sudden it stopped saving the pics. Couldn't get anything to read the card so I ended up formatting it in my backup phone. This likely was due to the camera app but thought I'd post just to add my experience

I have a 16gb sandisk from way back in 2012 yet still works lol but I was rinning into some issues this past weekend it kept telling me checking sd card for errors then it would mount and unmount so I rebooted same problem so what idid was to take the SD card out plug it into my PC backup my data even though the data was intact so I backed everything put the card back in turn the phone on and my data was still there I'm not sure if its something related to your issue but right now my SD card is working normally I love it lol

I've got a Scandisk sdxc 64gb since several months in mine and no problem till now.
