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.

Problem with memory card and windows 6.1

Hi Guys,
I have just upgraded from windows 6 to windows 6.1 ( got it from Australia HTC website ). After the upgradded , everything was working fine and I have noticed that it have improved the performance speed.
After afew days later, something funny has happened, all my programs and files that saved on my memory card was deleled. So I tried to do hard reset but the same problem happen again ( program and files got deleted from the memory )
Is everyone have the same problem as me ? Any suggestions what may be the problem ?
My device info :
HTC TyTN 2
Rom: 3.29.861.0 WWE
Radio v: 1.65.17.10
memory card : Sandisk microSD 8GB

I've never run into this problem until recently. Twice now in the past 4 or so days I've had all files and programs completely erased from my sd card. I haven't been able to isolate the problem and whether its rom related or software or just faulty hardware. I do see that you and I have the same sandisk uSDHC 8gb card though.

I got two cards one is 4GB and the other one is 8Gb and they are all sandisk uSDHC. It is really annoying that I have to backup the file to the memory card everytime.
I dont think it is the hardware problem at all. It is 100% a software problem.
Anyone can suggest what may be the caused pls ?

I just discovered yesterday that upon a removal and insertion into my memory reader on my pc the files were still there. (weird) I put them in my tilt and gone. So I soft reset the tilt and they are back again, including the ones I thought originally gone the first time. Go figure.

search for duplicate files/folders names in same folder.
this was my problem on artemis
with the same behavior as you describing

Same problem - Serious issue - must find Solution
HTC P3650 upgraded to Windows Mobile 6.1
8GB Sandisk has been wiped twice now since upgrade about 2 months ago
This causes great inconvnience I was about to complain to Sandisk about a faulty microSD card until a came across this article which tells me it's definelty 6.1 software issue.
If I buy a different make SD card will it resolve, I don't care I must have a solution I cannot work with this.
I would be very grateful to anyone who can can resolve this
I also noticed most folders show as duplicate when browsing the SDcard. This may be as mentioned by someone that they noticed data was still there when they plugged just SD card into PC, maybe I have restored previous data and current data was still there. Although you should not be allowed to have same folder names. This error really sucks

Running official WM 6.1 ROM with Sandisk 8 GB, I've just encountered the same problem. There was no problem for 3-4 months and suddenly today the SD card shows as blank both within device using File Manager and plugged into my PC. The strange thing is that under Settings/Memory I see that about 50% of SD card is full. Card Export also reports around 50% full. So is it just the MBR that's messed up?

i have a 4gb SDHC Kingston card and it has happened to me like 3 or 4 times in the last 3 months... once i was installing Uptodate, and other time i was installing Destinator...but i cant seem to find a pattern...!!!

Corrupt SD Card issues

Is anyone else having issues with their sd card corrupting? I have an 8gb class 6 transcend card and it has corrupted 3 times in the last month. I always unmount the card in windows before unplugging the phone. It seems to do it when I'm writing to the sd card from the phone.
The first time I noticed it was when I deleted a picture with built in photos app.
The next time was today when I made a nandroid backup before applying an update (theme). The nandroid backup finished and when I went to apply the update it came up with an error (I didn't reboot between the backup and applying the update). I reset the phone and the sd card was unavailable.
At one point I did have the card partitioned with the apps on one partition. When it corrupted I reflashed the phone back to 1.42 and left the apps on the phone. I went back to one partition and left it at that (fat32).
I don't know if I just have a bad card or something else is going on. I never had any problems with 1.41. However because it did it while doing a nandroid backup would that rule out the software version?
I would like to find a solution, as I don't trust the card anymore without backing it up frequently.

i've had it happen once (files names corrupted) but assumed it was down to the card as i had the same happen when it was in my N95, i've now bought a new card and i'll see how it goes.

When mine goes down, it seems like it kills the partition. When I open a disk manager I don't see a partition on the card anymore.

Hey axion,
Yea your card is pretty much dead... this also happened to me yesterday on my 4 gig card... yyour card will still work however reformatting or creating anymore partitions won't help bring it back.. for future update.zips or recovery boots upload your update files to your stock 1 gig card.. remember to always safely remove hardware with any card mounted to the to a computer..

YES - and not only have I had the same problems, it's with the same brand card! Transcend 4 GB Class 6.
My phone started having issues where I installed an application and it would act wonky, then if I tried to reboot it'd lock up into an infinite loop.
The last couple of times, I solved the loop by doing a fsck on the partition in GParted (booted into a GParted Live instance from a laptop using a USB stick). The problem reoccurs though, making me think there's something problematic with the card.
There's an app in the thread on the cheap 8 GB cards (of which I'm holding my recently received shipment . There's an app in that thread used to test write performance, but it does some crude error checking, and I had an issue when I did that test.
I'm going to do a partition clone and report back.

my dodgy card was 4GB Kingston, one interesting problem i had with it was video refused to play, i could read and write the file fine but android would refuse to play it and meridian video player would report the wrong pixel size, time and codec which had me confused all last weekend.

I'm also frequently having problems with my 8gb card (http://www.newegg.com/Product/Product.aspx?Item=N82E16820211341). Every few days I find myself firing up Ubuntu to fsck it and I always find errors. I often discover them when looking for a file on the phone (I usually do a find / | grep whatever and notice that I get "stale file handle" errors).
Should I get a newer/better card? I'm happy to pay more for a better one. I didn't know this brand, but it was the only class 6 I could find. If Sandisk made a faster card I'd get that, but I can only find a class 2. I have a 16gb Sandisk but it is only class 2 and therefore not good for apps, which is what I'm using the sdcard for.
If anyone can recommend a better one, I'll give it a try.
Does a 16gb class 8 exist yet? What about a 16gb class 6?

I just moved to the same card you have, mlevin - so I'll post back my experiences if I'm seeing anything.
I'm wondering if maybe moving the caches to SD isn't the greatest idea, since these devices aren't meant for continuous writes. If I have more issues, I might just move the caches back to the onboard memory.

Yeah, that worried me as well, so I moved my caches back to the main storage and only have app, app-private and data symlinked to the card.

If you are having problems after moving apps and data to your ext2 partition, you have to push the original init.rc and mountd.conf back onto the phone so you can wipe to card fully and restore it to the FAT32 file system.

I had a similar problem on my tmobile wing (variant of the Atlas which is a modified version of the Herald) running Windows Mobile 6 and Windows Mobile 6.1. I think it was also when I used the SD card as a place to store cache for PocketIE. Maybe that's the issue, using it as cache storage. (This is my theory, not something that has been confirmed.)

g1 sd card deletes itself
I am on my 4th sd card. I am not sure what is corrupting/deleting my data. I can copy over some music/video/pdfs/wtfevers and it'll stick around for awhile. Then BAM, music folder empty(had 1 gig of music in it). BAM, 1 of 3 video files corrupted. OH wait, now all 3 are gone. awesome. I keep a backup on my pc so I can copy it all back over once it goes south. I have the doodledroid drawing app on my phone and the folder will go corrupt - not allowing me to save an image until I delete the folder so it can reinitialize(create a non-f'ed up folder). Also, my picture thumbnails get f'ed so I have to delete that folder so the G1 can remake a new non-corrupted set. My PDFs disappeared about 3 days ago. Cards all formatted fat32. blah.
Frustrating.
I have root
kila-user 1.1 PLAT-RC33
Anyone else find a solution?
BTW, my sd cards were:
sandisk 2gb
sandisk 2gb
PNY 4gb (current)
Lexar 4gb

mlevin: I have that card. It's been fine...until I believe the other day. I was running 5.01H w/ apps to sd and my battery had died so I charged it. Upon turning it on the android screen kept looping as though it wasn't mounting the card. Worse came to worse and I had to end up reformatting the card and starting from square 1. Now that I reformatted it, I'm getting "insufficent space" errors when trying to install paid apps even though I did everything right.
I'm wondering if it is the card.....

SD card possible problem

I was wondering if anyone here is having problems trasnfering pictures from their computer to the Sensation. Once in awhile a window would pop up saying that their is a corrupt section on the sd card and would I like to scan and fix it but when I take the microSd out and put it on my computer, it says that it's fine. Another is when I am able to transfer picture files and folders and several hours later, it would be gone. It was weird. I double checked it to make sure it transfered and it did but later on the day to show friends, the file would be gone. Anyone else having this issue? Should have I formatted the card first or not?
thanks

not to dredge up too old of a thread but I am starting to see this issue now, with multiple SD Cards. I'm afraid its a hardware issue since the SD Card reader on the sensation looks to be at fault. This is for all file transfers, not just pictures, too.
How did you fix this (if you did)? Like you said, i can read/write fine with the card in my SD Card slot on my computer, but if this is a hardware issue I would like to fix it before my warranty gets closer to expiring..
