Problems with SD Card

Hi,
I have the following problem with my Qtek 9090 and my 1GB SD-Card:
I installed all applications on the storage card, as well as many documents and files.
What happens is that I lost data on the SD-Card on 3-4 occasions. The result is that some applications are obviously not available anymore.
Plus, many data files (PDF, RM, etc.) are corrupt.
I tried to fill the card on my laptop with big ZIP-Files and checked them afterwards (CRC-Check will proove file-errors), but everything went OK.
This leaves me with 3 possibilities:
- the card is defect and looses data randomly - how could I prove that to the supplier?
- I am running faulty programs on my Qtek (i.e. freeware emulators) - while trying dosbox for PocketPC for the first time, my Qtek freezed and I did a reset. After that the SD-Card was empty!!!
- The Qtek 9090 has some weird problem accessing these cards, resulting in data loss.
What do you think? Can anyone give me some good hints?
Thanks,
vma

try write lock the card?

Then some applications would not run anymore, I guess.
Also, I want to use a "My Documents" folder on the card, to make use of all the space.
It would be nice to hear from you guy's if you a) never had similar problems or b) did expirience the occasional data loss/corruption on the card.
Thanks,
vma

I have an XDA1 with a 256Mb SD card and I've randomly lost all my data twice now.
I have write-protected the card to (hopefully) stop it happening again, but if anyone knows why it's happening I'd be very grateful to hear from them.

On Friday my 256Mb card lost everything (together with all progs and applications on the Qtek 9090). It was something to do with Spb Pocket Plus but haven't really got to the cause.

I had a similar problem on my magician until I looked up the data system. By default my SD-Card was formated in Fat 16. After I formated it in Fat 32 the problems were solved. Hope I could help.

I lost all of my data on 512 MB Lexar storage card today. Only mail attachments and "ingnore my docs" are there. It really pisses me off...
I don't have any idea why this happened - it would be nice to know the reason. A couple of days ago I restored usin Sprite, that shouldn't clear storage card, should it?
Any ideas?

Is this my SD card giving me problems?

Hi All - I've got an unlocked 750 using it on T-Mobile. It's been working great up until a few weeks ago. It stopped downloading email. If I take out the SD card, the email downloads. Put the SD card back and once again email doesn't download. In fact, I can't even open the program with the SD card in place. The phone locks up. I've done multiple soft resets with the card in place and out.
Any suggestions are greatly appreciated.
Thank you.

Check out for SD card slot or SD card.
It is 5% chance to have that problem because of this but....
2 weeks no single SD card worked on my Palm.
every time phone notice me by some beep or sound but it simply does not recognize SD card.
I was planing to sell it for "couple of $" as damaged but i said to my self
"why not use it, it has plenty of internal memory about 50 mb. only i must to say BYE to mp3 or videos"
and once again i push SD card that didnt work and suddenly STORAGE CARD appears in File Explorer. I was happy
Now i try not to do open/close so much...
Viva la buggy Palm

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.
Regards
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

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.
