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..........

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,

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 Card filesystem corruption

My HTC Touch Cruise corrupts the microSD card filesystem very often. I installed SD Sentry to warn me of it so that I can soft reset the HTC and prevent the corruption to became permanent. I know there was a similar problem on the P3300 and HTC made a patch for it. Is there a solution for the Touch Cruise?

I doubt it's a wide enough problem to warrant a patch as there would be a lot more people mentioning this kind of fault. I suspect it's a dodgy connection in your SD slot. Have you tried re-seating the card?

Yes, I did pull out the card and put it in again. The problem remains. It doesn't fail while reading from it (nor writing), so I think it's not a bad connection issue.

My 6GB MicroSD card was acting funny. Files were disappearing but there were on the card if I read it on my PC, strange.
Anyway, I copied everything onto my desktop, formatted the card and put everything back and I haven't had any more issues since. Hopefully that did it.

I have come across another topic on this forum reporting the same problem. It appears as if more people experience similar problems ....

I have the same problem encountered. My 4G memory card has been corrupted 2 times in 3 weeks. It happen after I taken the pictures. the first time was the whole picture folder become some funny text with the .iff extension. The second time was added additional my document folder. My problem right now is that, I'm not sure is this my touch cruise causing the problem or the sd card.^o)

I found the problem, this is due to the defective sd card. although kingston claimed that their sd card without problem, however the problem gone after I placed the new replacement sd card. Anyway, I am happy now.

I had the same problem, since I use a diamond rom (from udk) it's gone...

I had similar problem after just 2 day of usage. I bought SanDisk 8 GB microSD card and put it in my HTC. After taking some pictures another day, the album froze. Went to File Explorer, the card was blank. System>Memory stated it is a 7.3 GB card (that's OK) and that it has 2 GB data written (that's also true). I tried reading data from various card readers, connected to a PC, but I had no luck. Some even couldn't see the card. I managed to reformat it and had no problems since.

I didn't have this problem when using the 1GB card included with the phone. But ever since I changed to a Kingston 4GB card (less than a month), I've encountered this problem at least 4 times.
My DCIM folder disappeared once, DCIM folder was emptied after using the camera once, the SD card was filled with folders named with random characters once, and my backup folder was emptied once.
I'm still trying to figure out what is the cause.

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.....

[Q] SD card media scanning issues

I've had this Samsung Captivate since December and just noticed this issue with my SD card. It's a 16gb card that's been in it since I purchased the phone. Recently I looked at my gallery and found that one folder that used to have ~400 pic now has over 4000 pics. Most of these are duplicates. When I connect to the PC and view the folders there are the original 400 or so. No duplicates.
Today I unmounted the card, removed it and remounted it again. Now, in the notification screen it shows "Media scanning... 0 %" for an exceptionally long time trying to scan the media on it. For about 20 minutes. This happened earlier today but eventually came up after I shut the phone off. This time I powered it down and it did the same thing. Just sat there scanning. Then it came up with a red SD card icon stating that the card was full. I am now in the process of transferring everything I can onto my laptop. I guess it wouldn't hurt to reformat the card after that and see if it continues to happen.
After reformatting it, it still did the same thing. Luckily I had an extra 16gb card available. I installed it and transferred all the needed files. It works fine, for now. Don't know why this happened, except possibly that the SD card wore out (?).
Anyone else have a similar situation with either the captivate or SD cards in general?

Erasing a broken SD card for privacy

Hello everyone!
TL;DR: Got a faulty Samsung card which reloads on any device constantly, can't perform formatting or safe-erasing.
So I bought this Samsung Class 10 EVO 32G card for my CM12.1'ed Galaxy Tab Pro 8.4 in June, and it ran smooth and fast until... about a week ago I left my tablet on one night (with charger), uploading traveling photos for backup at a slow upload speed hotel room. I got up to check my tablet in the morning and I kept getting an notification saying "Checking SD card for errors" and stuff. The notification appeared for about seconds, then reloaded itself (disappearing then popping out), again and again. :crying:
It seems that the tablet couldn't hold up the communication with the SD card for longer than a blink... At first I thought it might be my tablet too hot last night (it's cool in the morning though) and burned the card reader module, so I instantly turned off the device and removed the card.
It turned out that the tablet is ok and it was my card's fault... The backup failed within one hour after I went to bed. I got the same problem plugging it in my phone or PC. I can see the root directory in Window's Explorer, and if I'm quick, I can manage to open a few folders and see the files ok, except I lost all my recent documents and photos into a 20GB giant LOST.DIR folder... When a 5-second or so period expires, the explorer hangs and I guess the card got disconnected again...
I contacted the retailer for the issue. They offered a replacement but not a fix to save my precious data. I searched online for hours but don't seem to find a useful answer... Later I found that the card wont disconnect when I switch on the READ ONLY mode on my SD adapter (!). This discovery almost made me cry!!! :victory::victory::victory: I then managed to recover some of the lost files, minimizing the damage, but I find myself unable to format the card or safe-erase any files since once I switch off the READ ONLY, I won't get a steady mount. Even a delete or copy command will hang the system. That's a huge problem because I have quite some sensitive files, passwords laying there, reachable once you enable READ ONLY mode... But I can only get a replacement when I return the faulty card.
How can I safe-erase a card in my situation? Is there any software good at this? I'm really desperate for some help! Thank you very much in advance! :laugh::laugh::laugh:
