2gb SD card becoming corrupt

I used my Qtek 9100 with a PQI 512mb miniSD for a good few weeks and it worked flawlessly. I had another unbranded 2gb miniSD card and decided to copy everything on to that and use it so I'd have more space for music. To cut a long story short, this worked fine for a few days then I started noticing WMPlayer acting up. I checked the card and loads of files seemed to be corrupt. After playing around with it for a while I eventually gave up and decided it must be a duff card.
So, I bought a 2gb PQI miniSD which I had read good reviews off. However, I'm having the same issue. I've tried everything I can think of 1) hard resets, 2) soft resets 3) re-installing apps 4) formatting in a couple of different PCs with a couple of different card readers 5) formatting from the StorageTools on the phone 6) formatting using WM5torage.
I can install apps and they seem to be okay, but then when I try and run them I get errors and when I look at the card its because of corrupt files.
I have no idea what is going on and I'm at the end of my tether.
I'm using the latest Qtek 9100 ROM from their website. Is this perhaps a bug in the ROM? Would I be better with another ROM? Which one? Will this still leave my 'phone SIM unlocked if I use a non-standard ROM?
HELP? Please?

Hey,
I do hope this is within this topic!
I've got aLmost the same problem, except I have some files just disapear on my 2GB mini, and some stay!
Lost a GIG of music, and most of my WORD docs, [60MB] and it left me 2MBs after removing Skype!
Real WEIRD!
Ive got a 8125 and stuff on the SD card just disappears after I remove an app!
Since this has happed more than 3 times and the 2GB mini tested OK, whats up with the device!
Is it the connections in the device to the SD card, or what?
Thanks for XDA-developers!

I have a 2gb card in my Qtek 9100. I've had it for about 2 weeks, and I got the card the day after I got the 9100. Sofar I haven't noticed any missing files. It's a 2gb Sandisk
I just thought to add this. Do you have the enhanced performance option in RegistryWizard enabled, or have you made the registry change to enable caching of the file system?
I was noticing that my recent programs on the start menu were being lost on occasion during a soft reset. I disabled that "enhanced performance" (caching) and that problem has disappeared. It makes sense that it would cause data loss or corruption, since data is being cached, if the cache doesn't write out before you reset, you loose everything in cache. I didn't notice any real world performance increase, so I will just leave that disabled.
If you have that setting enabled, and soft reset often, then that might explain the data loss/corruption

Success!
Well, I got hold of CnetX Flash Format program and this seems to have done the trick. I installed it and tried formatting the 2gb card as FAT32 - this gave the same problems I had before.
Formatted it as Fat 16 with 32k Cluster and lo and behold its working like a dream. Copied all my stuff from 512Mb card to it and now I'm syncing all my music over.
Fingers crossed it stays this way!

Scrub that......
.....just failed syncing my music over. Managed to get 950Mb of stuff on the card and then it started doing exactly what it was doing before. Hmmm....i'm really stuck now.

Howdy,
Well now today all my stuff on the care is gone POOF excect one little word file and a few omaclock things and a few folders!
All music is gone but the music folder is there WOW!
I already reformatted a few weeks ago to Fat 32 form the other one!

You can get RegistryWizard here http://forum.xda-developers.com/showthread.php?t=255225

Hey d0ug,
Thanks for the link, and dnloaded it but I really know why, or want for?
Ok whats this for, the storage card or what?
Thanks for your valuable time, and really sorry for the extra stupid questions, as this device in not my first device but I didn't have any problems with the X50 so I didn't have to learn to work on it!

Yep I moved 1 + GBs music into a "music" folder again!
Installed a app from xda, here called omanclockscaller.exe or something like that and set the overclock (speed of the processor) to 240 and the underclock to 150 (which was stated to work on another 8125)
and my device FROZE to the max couldn't soft reset or nothing so I had to do the HARD reset!
Looked in the SD card saw the folder "music" and NOTHING in it, just blank!
All subfiles were gone, POOF!
When to the main area of the SD card and ticked on a Mp3 file that was sitting there and it said player said "file stopped." 70%
Went to another MP3 file, tapped, and it said blah, blah "end of file" and would not play!
SO everything on the SD card, cept dah empty folders are either
1. corrupted
OR
2. GONE bye bye!
So NOW since the 8125 might not be the "slowest" brick on the block, and wont run, Skype unless its "overclocked," and I can't go thru another 50 some pages on xda to find the "fix" for dah SD wiping weirdness, and the overclocking tricks of the techs, I guess I get to go to Cingular, exchange dah phone (as it ain't no good as a PDA, but a great heavy phone) and than sell the NEW one on ebay for 350 with the New 2200MHz extended battery, and someone who is more techey than I can enjoy tweaking the thing!
Ive done 5 full Hard resets and have had to redo most everything, 5 times, settings etc, and its getting real time consuming, to state the least!
So since I got this pos on ebey and it has a 2yr. warrantee I guess its getting ready to get gone!
Hope someone like d0ug can help you out, really!
Later!

What brands are the Memory Cards? Where did you buy them from? Is it just in the Wizard that the card is being corrupt or does it work flawlessly in a memory card reader? Cause from what I've read it sounds like PEBKAC.

Card brand
My first card was unbranded so not overly surprised I had problems. This one is PQI but I think perhaps its because PQI cards are MLC (multi layer construction). Apparently Sandisk are SLC (single layer construction) and they should work okay.
I might just have to fork out more money and see.
The card works perfectly in my PC with card reader.
Excuse the ignorance but what is PEBKAC (or should I not ask!)?

Ah the reference to PEBKAC was more about the other guy. I think you've just got unlucky with the memory cards.

Does the MLC/SLC thing sound viable? Has anybody got experience of using Sandisk 2Gb cards with the Wizard?

Hey scottjames,
I don't know if this helps as I was using Winamp files and wasn't using Win Media on my PC so that may be why the files got corrupt or just disapeared when I went in again and tried to play them!
So I diched Winamp and am using the gates special and so far so good!
I don't know if that may help but hope so!
Cingular is going to exchange my phone for too many other reasons!
Have a good one, and thanks everyone here!

I've been using a SanDisk 2GB card to capacity sine April of this year, I change the contents of the card pretty often as I use it as my mp3/video player, using both the WM5Storage program and a memory card reader in my PC. Has been flawless.

But
when I go file explore > Device > SD Card I see all the music file and even play them OK
WOW thats real weird!

I filled my card lastnight, and have used the pda as normal thoughout the day today. accessed files, copied files, created files, deleted files. I'm not having any issues with my sandisk 2gb.

Thanks
Thanks everyone. I'll maybe just get myself a Sandisk card and let you know how I get on.

I have a Sandisk 2GB and whilst not experiencing the issues above I do have other problems.
When accessing eBooks via Microsoft Reader or playing video files via TCPMP the device will occasionally freeze and the apps cant even be killed by the taskmanager. I have a standard TMobile install and these are the only two additional apps that have been installed.
Ejecting the card usually frees it up.
To be fair I haven't yet tried the card in another device to establish if the card itself is faulty.

[Q] 32 gig card trouble

I have recently purchased a 32gb micro sd card. When I go to put new music on it, it shows from the pc side that it is loading on the external drive(g2 phone) and form the phone it says that it is on there. However when I disconnect the phone only the last album that I put on there stays and the music player will state that "this type of file cannot be played". I have formatted the card through the computer and to no avail, it acts the same.. I did format it on the Android and it worked, temporarily and could load music from my computer for a few days, then it stopped. I am clueless as to what is going on with it. p.s. I tried placing it in a card reader and it did the same, but i did not format it first that time. I seem to think the android is placing a bad file on it causing all these issues. (again I say this because when I format it through the phone it will work temorarilly) any help would be great, I really want toload my phone with music.

Put the same file on a known good SD card. If it stays, it's a bad card. Most of the time the company the card came from will replace it for free (like Wintec did with a bad card that couldn't handle an EXT4 partition).

It is not just one file, it can be multiple files, like I stated in the other thread (I apologize to do two on here, but I rarely have to ask for help, I am usually able to figure the problem out, but this one has got me) I have checked the card with h2test and it states that it does have 32 gigs on it but that the card is corrupt, I have formatted the quick way with sd formatter. What puzzles me is that at one time I was able to load more on it and now I cannot. I feel that there is a fix, I am just not finding it yet.(okay im testing while updating, if i uplug and replug the phone and place music on it, it will only keep the last folder, for instance i put nirvana nevermind on it, it will keep it, i then put a folder with two albums on it, say radiohead the bends and kid a, it will replace the last one , I am certain that space is not the issue, due to having placed less files on it the first time I restored the card agai)

Did you buy this card from ebay? A lot of counterfeit card on there. Cards that say they are 32gb but will only hold a quarter of that.

Try writing zeros with dd to the card... but be careful, dd will destroy anything you point it at, without hesitation. This is a typical dd command:
$dd if=/dev/zero bs=1M count=32000 of=/dev/somepartition

Where did you buy it? Like others have mentioned, it sounds like a counterfeit or broken card.

what is dd, and how can i tell if it is fake, every program ive used to check it goes through 29gigs of partition

DD is found in the terminal emulator on linux/unix systems. Be carefull, you can destroy everythign on a partition with it.
Also, you'll have to reformat afterwards ... the sdcard

Lots of the counterfeits are tampered with to report the "alleged" GB capacity. Its not until you try to transfer the files, that you run into problems and realize you were taken.
Again, where did you buy the card???

I apologize for not having answered your question, I bought it on eBay, I have been given a refund though. Where should I look for one at instead?

I got mine on amazon for like 55 bucks a few weeks ago been working great. It was a class 4 adata with a little blue usb card reader.

okay i bought a sandisk from a trusted store and again same thing, i am lost

What trusted store?

newegg class 4

Yup, that's about the must trusted store there is!
Any luck with lower capacity cards working? I'd say maybe its just a defective card. But its weird to have a string of bad luck like this. Is it possible the SD card tray on your phone is damaged?

Do you have an after market battery? Just curious...

(Guide/How-To) How to Fix a Non-functional microSD

This guide/how-to will show you how to fix your non-functional microSD card.
Things you need:​-Broken microSD
-Blackberry (tested with a Curve)
That's it!
How I came across this fix and some backstory:​Your microSD card might not really be broken. Just follow these easy steps to fix your "broken" microSD. The other day, I tried to flash a ROM from my external SD. In recovery, it said that there was no external SD mounted. I knew that wasn't true, so I took a deeper look in. I also tried to manually mount the SD card in the settings menu. I tried changing my ROM, trying putting the microSD into different devices, but no matter what I did, the microSD couldn't be read. I even considered returning to stock.
I was on Amazon, already looking at some new UHS-1 Sandisk cards. I figured I needed a faster and bigger card anyways. That was when I noticed a Blackberry Curve next to me. I hadn't tried putting the microSD in it yet, so I said to myself, "What do I have to lose? It's already not working. It can only make it better." I put in the microSD and voila! The BlackBerry recognized the card and asked if I wanted to format it. I hit yes and the BB formated the microSD with no issues. I put my microSD back in my T-Mobile Galaxy S2, and guess what? The phone recognized it! Another plus is the fact that with the BlackBerry format, there was only one folder. Normally, when you format a card in a phone, there are A LOT of folders. I just deleted the BlackBerry folder so basically, I had a completely empty card.
Formal Instructions on how to fix your microSD:​1. Put your not-functional microSD into a BlackBerry.
2. The BlackBerry should ask to format the card. Hit yes.
4. Connect your microSD to a computer. Open it up.
5. Delete the folder called "BlackBerry" (optional).
6. Your microSD card should now work fine.

If you get *really* desperate, have stuff on it that can't be replaced, and have a few days to burn, you can also try to rip the bits from it using an Arduino (or any other microcontroller).
The easy part is pointing at address=0 and sequentially reading it a bit at a time, byte by byte, via SPI. The *hard* part is interpreting it as a filesystem. I know code exists for FAT32, but I'm not so confident about ext2/3/4 or NTFS. For those, you might have to come up with a way to get the raw data into a form DD can recognize.
The point is, a microSD card is pretty hard to physically destroy. It's one of the few devices we have left that can be low-level read by fairly simple means (in theory, you could probably read it with a 3v DC power source, a SPST toggle switch, two momentary buttons, a LED & resistor, a soldering iron, and some wire... one button for MOSI, one button for SCK, and the LED for MISO. Flip the switch to transition ~SS from high to low to reset the latch, and press away. Ok, maybe debounce it, too...
It wouldn't do you much good that way, but it's an example of just how easy it IS to rip raw bits from a microSD card. No real timing requirements (AFAIK, microSD timing is entirely static). Apparently, this is kind of how the first home computers worked, too...

More to the point how about doing some basic fact-finding first and finding out what errors the kernel on the device is reporting when it tries to mount the sdcard, then steps can be taken to solve the real problem rather than relying on magic and what some people might term as beginners luck! A good place to start is
Code:
adb shell dmesg

SD Card is Damaged. Try Reformatting it.

Anyone else getting this with their S4? I bought my S4 two weeks ago and a Sandisk 64gb card to go with it and started seeing this error about twice a day. I returned it for a Samsung SD and didn't see the error for almost a week until today.
The card actually appears to be fine, all I have to do is remount it after seeing the message and all is good, it's just worrisome cause I store all my photos on there. I'm wondering if it could be the phone itself? I have one day left to exchange it, but it's rooted.

SD Errors are because the card is physically moving when its being written to. This cause bad sectors on the card. Try putting a piece of thin scotch tape and cut to shape of the face of the SD Card. See if it fits more snug....
Are you jogging with the S4 or something? Samsung SD's are class 10 which I think write faster. Maybe that is less likely to cause damage because its written so fast? Not sure....
Try the tape trick and see if it reduces the problem. Else its a physical problem with the slot.

i also have a class 10 64gb, some guy on the forum posted this problem too, he said that by formating the card with a PC and then formating it with the format utility in the phone settings has solved his problem. If not, might be a slot problem like slider mentionned

I had this problem too with my 32 gig class 10. When I put my shock absorbant case on it my problem went away

I had never had an issue with a Sandisk card until my S3 ate a 32GB. I then started readibg how the S3 ate non- Samsung cards. I have been using a Samsung card with no issues

hope you make regular sdcard backups and copy to pc
polish_pat is correct, reformat your card with sdformatter, use Full Erase On and Size Adjustment On
Of course backup first
you shouldn't have to reformat again in phone--
if the card is good this should solve your issue

I had tried 3 different San disk 64GBP class 10 cards and had this problem, the fourth one works so far...doing some searching I found lots of complaints from lots of different device forums about this card. Only fix I found was running chkdsk repair on the card in Windows but this only worked for a few people ( couldn't save my first three cards)
anyway, imo exchange the card or better yet buy a different brand

Posting here as doing a search revealed this is the closest to the problem that I'm having. I've had my AT&T Samsung Galaxy S4 for approximately 1 month now. I purchased a Sandisk 32GB SD Card for the phone. Two days ago I began experiencing issues where when unlocking the phone I would notice the card would unmount then remount (this was in the notification bar). Later that night, the card unmounted and there wasn't any way to get it recognized again. I posted in some other forums and someone said there were some good posts here.
I've contacted Sandisk regarding the card and they refused any involvement stating it's a problem with the phone, not the card. They determined this because once I was able to get the phone to recognize the card and plugged the phone into the PC, the card was able to be read. As long as it's readable, it's fine. After dealing with this I eventually found my MicroSD to SD reader and plugged it into my media reader in my printer. I had quite a few issues from time to time reading the card, however I can't 100% for sure say whether this is the card or the printer.
Anywho, I grabbed copies of what I needed. Formatted the card on the PC, then formatted it on the phone. I began to copy my entries however at one point instead of saying I had 29.* GB Available, it said something like 2.0 EV of 3.0 PE or something like that... these weren't the typical numbers I've seen nor the units of storage space. I apologize that I can't recall that information. I reformatted again and it worked. Left the card in the phone empty over night then tried to copy files later today. This worked.
Now, approximately 48 hours after the problems began, I noticed more issues. SD card stated that it had been damaged and that I should reformat it. While this message stayed in notifications, I confirmed I was still able to read files on the SD card. When googling that error hoping I'd find more resources, the card again unmounted.
One of the resources I found had me do a CHKDSK /F /X on the card. I did this and found no issues. I've replaced it back into the phone and it seems to be working for the moment.
1) Are there any confirmations if this is a bad card, or if perhaps any applications are causing the card to do this? I do have QuickPic and have enabled some of the hidden file features if that helps.
2) Do we know if there are any logs that can be pulled to help verify this?
3) Is it a specific card? (I've heard SanDisk 32gb, but also have heard non-Samsung SD will fail)
Looking to get this resolved ASAP. This card was purchased directly from AT&T when the phone was purchased. I am just looking for some confirmation that if I have to buy another card, I'm not going to gamble if that's going to have the problem as well.
Thanks! If I forgot anything please ask!
Edit: Per the thread, this is a Class 4 card. Also the phone was not moving when it was writing data. I've been couch-ridden all day and unlocked it. I don't believe the phone was in deep-sleep mode as I had received a text not long before I began noticing these messages.

same problem
i have the same problem and guess what ?
the phone is acting like the ***** it stays ok for 3 weeks while that time i download to many stuff to my ext card 32g Elixir Memory after that it crach and give me notification that sd card is damaged and i have to reformat it sucks

This works! It fixed the issue I was having with my SanDisk 64GB.

SO SD Card Issues

So I got this phone a few days ago. I use jet audio plus for my music and have about 30gb of music on my SD card. Pulled the card outta the old phone and put it in here. It reads it fine and saves all my photos. I noticed that the music app will sometimes go blank for a minute and my playlists will empty. After a few seconds, the music all comes back like it is rereading the SD card. First thought was maybe a problem with the app so I emailed the dev and they told me to troubleshoot and see if it happens with music not on the SD and then try music on the SD on Google play music.
Problem did not occur with music on internal memory. Problem did happen in Google play music. So then I checked my photo and noticed the galleries do the same thing and go blank for a second and then reload.
The memory card is maybe 2 months old and it's a higher quality one with a good speed rating. Before I was gonna reformat it, I figured I'd check online and see if anyone else reported an issue. Sure enough, I see samsung.com has a topic in their forum and tons of people are complaining about the same issue with many different sizes and types of cards. I was surprised that this wasn't posted here yet (at least from my quick searches).
Anyone else experience anything similar? Any feedback? News?
Auto correct changed S8 to So in the title*

Still no update on this issue. Thread on Samsung forum is 8 pages long of people troubleshooting, so far no solid fix. I'm not (knock on wood) experiencing the random reboot issues that others are. Perhaps those who are should download SD card monitor and see if their card is going crazy too.
https://us.community.samsung.com/t5...cpage/board-id/GalaxyS/thread-id/22859/page/8

All I can say that when my card started disconnecting like this on my previous Samsung phones, it went bad withing few weeks, I mean bad like not able to access it at all. If I may suggest, do full back of everything on that card, also check LOST.DIR, if anything is there you already have some files corrupted/lost. I don't know if this is SD card issue or phone error corrupting the card, but I lost about 4 cards this way over the years, but nothing recently and my S8 works fine.

Try backing up the card and reformatting in the new phone. I had a similar experience going from the s6 to the s7. No issues with s7 to s8, so far, though.

I've had very bad experiences with memory cards and cell phones. To be fair though, those were crappy memory cards I'd bought and I certainly got what I paid for. Now with this new 256gb Samsung EVO card, I'm hoping good things for it. Reviews certainly paint it in a good light.

I'm running the Xtreme level SanDisk. I am worried about the card being burnt up, but I don't know if it's the problem. Tried other cards like other people have in the topic I posted, same results.

I just want to say that I have personally have had VERY bad luck with SD cards I get off of Amazon. The ones I buy at a store never suffer such issues.
This is just my own personal experience, others may differ.

Issue still on going. More and more people reporting this on the Samsung forum.

Have people tried formatting using the phone? I haven't had a problem yet.

I formatted a Samsung 64gb ultra as card that I got from target with my phone. It disconnects. It has nothing to do with Amazon, or cheap sd cards.

One thing I thought of, make absolute sure the card is seated flush in the holder. Sometimes a corner will fight its way out. I put it on my desk and lightly pressed until it clicked. Obviously you may have too but I'm just trying to think of things before blaming the card reader in the phone.

Yes, people have tried all kinds of trouble shooting. A lot of people formatted in the phone and on the pc

Yeah right after I made my last comment I went and checked that. It didn't go back in until it was as flat as possible. It seems to be working so far. I also polished the pins with brass polish to ensure a proper connection. I'll come back later to update if everything stays okay or not.

Having the same sd card problems with my Sprint S8+. Sometimes it reads it and sometimes it doesn't(ghost icons) with constant different sd card notifications .
It's a new 256gb samsung evo pro card that came with the $99 immersive bundle from Sam but tried my 64gb pro card out of my Note 4 and same thing. Of course tried formatting,reseating card and sam support said it had to be encrypted which was no help.They did give me a ticket and label to send it to them for repair.'
Now the question I have.......are there people that are having NO sd card problems with putting apps and folders and such on it ????Wanting to know if it's a possible bug/software problem that will have a fix or a hardware problem with my phone and think that I should send it in. Never had any problems like this with my Note 4!

My sd card seems to be fine after reinserting it.

I have not come across any issues with my SD card (Samsung Evo 256GB) on US S8. No error messages what so ever. Actually kind of surprised, since in the past almost every Android version update brought some new permissions and messed up some form of SD card access. The messages about removing SD card is not normal and it will corrupt SD card if it happens during write cycle.

Did you encrypt your micro sd?

No apps. Hundreds of folders, thousands of files. SanDisk 200 gb.
I am getting some strange issues related with write permissions on micro sd with some apps. I think are related with encryption. I am testing.

No encryption, I don't believe in full encryption, most of the stuff is pictures and videos which don't need to be encrypted, for things that need to be secured I use secure folder or encrypt the file itself. Also I don't care what anybody says, encryption increases usage of CPU, slows it down and uses battery. It also increases the risk of corruption and file error and in case of some errors there is no way to access it from computer to recover data.

Update: disabled micro sd encryption today and write access permission issues seem to be solved so far.

Sd card disconnected again. So obviously the slot is loose garbage. I put the phone in my pocket while listening to music and the music stopped. I pulled the phone out and the sd card was unmounted. The sd was a huge reason I went with this phone and It's ****!
