OK, seems I understand the issue, and seems also that I cornered the issue.
First, the card is working normally while DEVICE ISN'T SLEEPING.
Second, it happens mostly while WE'RE SLEEPING AT NIGHT or WHILE THE PHONE LEFT DEEP SLEEP (Paranormal Activity? LOL)
So, based on this: something in kernel/ROM/anything that control the power to SDCARD doesn't provide correct/adequate voltage or electricity to the SDCARD while the phone in DEEPSLEEP.
Or: the card don't want to be suspended in deepsleep, it just removing itself when instructed to sleep (this one is the card's fault).
And: any card thats been badly removed thousands times (it can do around 20 bad removal at 7h period so, count it yourself), its become broken/unusable but not fried as stated in many site). The chip broken,yes,but due to bad removal thousands times....
So, any response and research is needed on this.
Also disassembling the device to re-plug the sd/sim module flex inside doesn't help at all, so don't bother with it.
I'm really into this really, because my SIII has already killed two 32 GB Class 10 Cards... suddenly the last one was a week ago I copied a filed restarted phone to recovery and boom SD gone... so I will check this post I think that the SD card killing case was only a few people but it seems like a major problem.
This is caused by bad quality SD cards. SanDisk already admitted it as a failure on their side.
I've already spent countless methods in trying to debug and fix it. I solved it by buying a new card.
Hmm, so the moderators can delete this thread as it seems that this doesnt need any research...
Coz many also said that using Samsung's card also got this trouble...
[solved] sd card umounting galaxy note 4 autosync dropbox
There are security files on the SD card that are markers that can't be over written. Simply copy all your data to a pc. Then format using the note sd format. Then copy only the important files like pictures movie ect. It's a security feature just start over.

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.
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 .
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.
I've been using Dexter's froyo v1.3 for a week or two now, with basically no real issues. About 3 days ago or so, when I powered on my phone - you know how the sd card symbol appears in the status bar right when u turn on phone, it's loading sd card - so I see that symbol, but unlike how it usually is, it doesn't go away after a second (after it's loaded). So I pull down status bar and the icon says "checking for errors" and it doesn't go away at all. SD card just won't load. Oh I should mention -just remembered - I turned it on and I got "error with sd card, you may have to reformat" (or something like that) right before and then it just changed to "checking for errors" after I took out the sd card and reinserted.
Anyways, so my SD card isn't loading, right. I figured it might have something to do with the fact that I was using the SD card that came with it which is low class (2). I tried putting it in an SD card reader and put into my computer and it showed up and worked with no issues. But it just wasn't working on my XT720. So what I did was, I happened to have an extra micro SD card lying around (this one class 4) and I put it into the XT720. It worked just fine. That was a few days ago.
A few hours ago, I was using my camcorder on XT720. After using for quite a while I got "sd card not present, sd card must be present to use camcorder". I left the application and went to settings and my sd card was registered as present. I then went to gallery but I got the same "sd card not present" thing. My phone felt very hot at the time, which I assumed because I was using it for a while. I figured it might be an issue of overheating causing weird things. So I decided to power off my phone for a while and see what happens.
Upon turning on my phone, I was greeted with the SD card icon in the notification bar and upon pulling down; "Checking for errors". Now this new SD card won't load.
This is a really big issue for me, because I really need the SD card for stuff. Both SD cards seem to work fine in SD card reader on PC. Please let me know how I can fix this...
(sorry for making this so long, just wanted to have all info available).
....
Apparently this looks like a huge, long unresponded to issue for many people and not specific to Dexter's Froyo: http://code.google.com/p/android/issues/detail?id=2500
I'm going to try some of the solutions people posted, but problem seems unfixed for majority of users .
Gaaaaaah. My Android experience has been plagued with far too many issues....
What sucks is that if I want to flash back to stock to try to use warranty, I'm going to have issues if I need an SD card....
It seems you've already determined the issue, you have excluded the SD card(s) as the source of the problem. This leaves one thing - your phone is defective.
Flash it back to stock and send it in for service.
This issue has absolutely nothing to do with what software is on your phone.

You don't need the sdcard to flash a stock SBF with RSD lite.
I kept having same problem. If u are using move 2 SD or anything like that select auto and not Justin external I had to reformation my card about 3 times b4 I figured it out. Dexter posted somewhere not to use these apps.
similar issue with sd card
The only problem I've had with my sc card is that most of the time after my phone has been rebooted, the sd card will show up as not present once the phone has completely finished booting. Sometimes I can just reboot again and it will pick up on it but usually what I have to do is shut it down, remove the card, start it up and then once it indicates the sd card is not present I can reinsert and it loads just fine. I have an 8gb class 4 that came with the phone.

I tried that once (it was something mentioned in that link I posted) but it didn't work. I'll probably try it out again before attempting to use warranty.
I would also try reformatting the sdcard, just because Windows can read it doesn't mean there aren't issues with the card.
K, so I put it in SD Card reader and into PC and began transferring all the files on the card to a new folder. During this process I got a pop-up a bunch of times telling me specific files were corrupted and unreadable and couldn't be transferred (mostly music filer for the most part). I then formated the card to delete the remaining corrupted stuff. Now put into phone and it registers as being there and now things like camera are working.
Gonna have to see how it fares when stuff are actually on the card, but for now things are looking good.
Thanks for the help guys, will update if I encounter further problems.
EDIT:
And after transferring some music on to it, it still seems to be working fine. Needless to say, I'm quite happy I don't have to go through the hassle of flashing stock and then trying to get a device exchange for warranty...
Though I am slightly worried that the device itself will corrupt things again (since my other SD card also worked fine for a few days). But I did also do a complete factory reset so perhaps there was some app causing issues that no longer will... Guess we'll see what happens.
I had problems with my stock (Cincinnati Bell) SD Card doing a similar thing -- showing up as no card inserted. Sometimes rebooting did the trick in fixing it. Then my phone fried and quit working. I thought it was related.
After I received a new (refurb) from Motorola as a warranty replacement, I used that same card and was getting the same error. So I upgraded to a new 32GB class 4 card and still got the error. I upgraded to Dexter's ROM and it still continued. I'd keep rebooting (three to four times sometimes) and eventually it would go away.
Then I decided to pull everything off the card, reformat & give it an ext3 partition using the method in the video tutorial in these forums. I haven't had the issue since -- it's been about a week now.
Hi guys I have a relatively new z3 the problem is I broke it really bad and most of the damage is in the sd card side, now this might have nothing relevant but info is info right.
So my Z3 makes my SD cards frozen in time, basically whatever change I do gets reverted. I tried formatting, nope. Just reverted. Whenever I delete something it comes back but the file changes to new, like when I delete old pictures they show up at the top of the latest pictures.
This has happened with 2 different 64 gig sd cards so I'm scared to try another expensive one but I've been using a 16 gig card and so far (1 month) so good which scares me actually.
This is like the internet cafes with deep freeze installed you know? Whatever you do once you restart it restores the image. They're just frozen, I can download things and add things but can't delete things or "write" things. Also I couldn't hook it up on my PC with the bad sd cards but the moment I took them off voila. The pc could see the phone without lagging.
What can I do? Does anyone know even what this is? Z3 did this, not the sd cards as it happened with 2 seperate cards. Both happened the same way, I was adding files via PC then lag came, non responsiveness then they got "frozen". I also can't use 'em with SD card adapters.
This seems to be the same problem but with the different phone, it acts as deleted but comes back. Like readable but not writable.

I am at a loss... I have a Samsung Galaxy J7, (sm-j700p) and I have a 64GB SD card in it. It was working fine until thirty minutes ago, and a preexisting problem reared its ugly head; The battery the device comes with does not have the proper voltage to power the device when it's under a large amount of stress. So when the screen spazzed out, I thought I knew what happened, and I just powered off the device, popped the battery out and then let the device fully recharge, which fixed the problem. But unfortunately, a new problem arose. The apps I had moved to the SD Card weren't loading in, as if the SD Card wasn't inserted. I went to the Storage settings (Settings>Storage) and low and behold, it was reading it as mounted. So I jumped over to Total Commander (my 3rd party file browser) and found I could access and manipulate the files with no problems. So could anyone tell me what happened? And maybe how to fix it?
[EDIT] I have fixed the SD Card, basically copying the data from the SD to my PC, then formatting the Card, and setting it up on the device before restoring the files. The only problem I face now is when I move apps, the phone either has no problem with it or restarts immediatly.
