Had to return my 3125 because the microSD cards would become corrupt for no reason. This happened twice. Thank goodness I was able to return the microSD cards as defective. This is what happened: Folders/Files would disappear out of the blue. No programs running, no nothing. Listening to music thru my Motorola Bluetooth transceiver(A2DP is very cool). Shut everything down. A couple hours later, Music folder invisible. It's still there, you just can't see it or access it. Take the card to my PC and it does not recognize the microSD card anymore. Hangs everything up. So, from my phone I delete everything from the microSD card. Check the Properties and it shows there is still a gb of data on the card. Now I'm just pissed, so everything goes back to the store. I still had a few days on Cingular's 30 day return policy (Cingular is great). I read a few other threads where people were havng the same issue. Buyer beware. [Applied the A2DP hack to my 2125 (which is a better phone - better reception, easier to use with one hand, ect...) works great - see http://richtech.wordpress.com/2006/05/11/go-wireless-on-your-cingular-2125/
for instructions. I did NOT upgrade my ROM before performing the modification. I still have ROM version 1.0.9.0 and everything works fine.
could be a microsd card problem
would you please post you microsd make and model?
i am currently using a transcend 1gb (normal speed)
been using it everyday for music(yeah a2dp is great) photos documents .... etc
all is fine .. the normal speed doesn't lags so much like when it was on my ppc
I was using a Sandisk (normal speed) microSD purchased from a Verizon Wireless retail store.
I lost a folder (Application Data/Home) during the night without touching the phone. Had to send it in, and received a brand new one back. I do NOT have a memory card at all!
I too is using a microSD card of Sandisk but it dosnot has ne problem.
there is a similar post on howard forums. I had this same problem happen to me twice. Both times it was a sandisk 1gb card, but one of them was the ULTRA model. There is something frying SD cards...and it's not based on brand. I have the qtek 8500 and it happened

I have read somewhere on these forums that if u let ur device to charge for more than 3-4 hrs or leave it by accessing gprs for some time then the device gets hot and can fry ur sd cards or ne internal chip.
dude... i am having the same problem as you... the funniest part is that my Micro SD goes corrupt every 3rd after the reset of the phone or i uses the handfree kit.... but i am using a Dopod S300... is it really the card problem or the phone? i am still figuring out.. cause each time i take my phone to the shop the Micro SD will just be back to normal after 1 hour... but i am using only 512mb
Thanks for viewing this post.
I have been encountering a weird problem for some weeks. Whenever i reboot my optimus, memory card isn't recognized. No used/free space counter in settings, it's as if it just isn't there. Then, after some time "preparing sd card" appears in the notification center.
But the problem here is it isn't definite when will it appear- it can be after 5 minutes after booting or 7 hours. its just random. had been encountering it in cm7 for some time, thought ics would fix this problem (wiping everything). Worked like this for two days in ics.
Until tomorrow afternoon.
Now it just isn't recognizing it.
That's why i opened up my first thread.
Seems like the sd card read initialize settings are messed up. Used to be A flasher, but flashed my first ROM in two months, two days ago.
Ps: oh, and when it was getting recognized, the size of .androidsecure in root of the sd card wasn't getting analyzed, in windows it was.
Share your similar experiences, thoughts and let's come up with a solution to this one.
I think this is a hardware problem...
I believe by hardware you mean sd card. maybe but it works perfectly in windows pc, as well as Nokia phones.
Maybe the card holder (which, well, holds card in place) is acting up.
A point to be noted- other cards work flawlessly, and my card doesn't works in other phones. So, must probably (!) The memory card is the culprit.
Bought a new one altogether.

Hey all,
I thought I would share my findings to help others with the same issue.
Two days ago I kept catching glimpses of a card image in the notifications at the top of the screen, but it would only be for a second so I could not see what it was trying to tell me. But had a quick look and sd card seemed fine and all data was present on handset. A couple of hours later it popped up with "SD Card Unexpectedly Removed". I tried ejecting and reinserting,restarting device and turning off and removing battery all to no avail. So I did a quick search which showed this seemed to be quite a common issue, after reading many threads with people saying the sd card is corrupt or network providers saying it was software and to do a restore. I decided before all that hassle I would open the phone and check the circuitboard expecting it to be a dry solder joint. One thing I will point out that was different to some other users is the fact my sd card was not visible with the phone connected to the computer, so this may not solve all related issues.
THE FIX
Turn off phone, remove the battery, SIM card and sd card. Remove all screws except the one by the 3.5mm jack. Gently pull the white plastic trim that surrounds the card holders and battery but the top part with speaker and camera does not need removing. Once removed if you look to the left of the sd card holder you will see the ribbon that connects the sd card to the main circuit board and at the end of the ribbon is the connector. Mine was disconnected and was loose, even if yours is not loose it would be worth gently pulling it off and reconnecting it. Then reassemble in the reverse order.
This was a nice surprise in the sense it was a very simple fix. However when I mounted the sd card even directly in my pc it was not found, I assume that the loose connector floating about had probably shorted its connections and caused an issue with the sd card. After a handfuls of attempts at mounting it in my pc it was finally detected and I backed up all the data and reformatted the sd card, then copied the data back,mounted it in my phone and was happy to find it all working as expected.
I hope this information will help some of you out, as it was a simple fix to a simple issue and results from searching had no solutions, just lots of assumptions.
And what can I do
Hi
I read your articles and seem very good but u have a question.
I had the same issue and I saw that every time my phone said I hat message it creates in my sd card a folder named lost. I and then i saw that one part of my battery was going there, ti reconnect the phone with my sd card
I formatted my sd card and did all the things that I found in the Internetbut nnothing works and I just change my sd for another one I had and sincethere u ddon't have any other issue, but my computer detects very good my first sd card and I'm not sure how to fix it.
Any idea?
Regards
Recently ive just faced this issue, what I did is to insert my 32gb sd card in my PC and run CHKDISK, havent got any error while performing this, thereafter i inserted it in my phone & goodness till now this sd card error hasn't appear yet. (finger crossed).
Mine did something like this a few times and then the 32GB Sandisk class 10 card died. Couldn't get it to work in any device except Linux based Media player. Luckily managed to copy my nadroid backup and TB backup. Sent to Sandisk and they replaced it. There is already a thread about S3 damaging teh SD cards. May be the loose connection is what's causing the card to to end up dead.

Yeah,as mentioned I have seen a lot of issues about sd cards, this is the first issue I have had and thought it would be worth mentioning. There is little space when the case is together so it could easily still make contact and seem fine even if the connector has worked loose and cause all kinds of issues. As mentioned mine had the sd icon popping up every now and then before it actually failed. Some users seem to be going through a lot of sd cards with them failing on a regular bassis.
I've been using my 32gb card since my last phone which was the LG Optimus 3D it is a scandisk class 10 one. Anyway i took it out of the 3D and stuck it into my S3 i still have not had a problem. I did take it out a few times to put a rom in because i wiped my phone and didn't have a rom in the Sd card. Also i dropped my phone and replaced the whole front silver bumper bit the whole digitizer because i dropped my phone while playing basketball. It still works. It has been a year now it has been in two phones and still works great. I must be lucky..
I got mugged for the SD though i bought it last year for £60 from Argos a store in the UK. Now you can get them for half the price oh well.. I am waiting for the 128gb ones to come out so going to buy one lol..
today also my Sandisk Ultra HC I 32GB it's died, tomorrow I'll test with pc but no sign of life :crying: WTF samsung !!!
hey i have the same issue with an 32gb sd card, it was workking great and then i was getting the error about
"SD Card Unexpectedly Removed" and then i tried everything i could and my computer detect the sd card and it seems to be working normal but in my phone i have the error over and over again and it was draining my battery too, and the only thing i did was change to another 16gb sd card and this one is working.
maybe there is a problem with the 32gb sd cards
I have a 16GB Sandisk UHS-1 card and i have been getting this issue as well, and its becoming more and more frequent. Whenver it happens, the ringtones/notifications for certain apps like Gmail and Message get reset as the ringtones i set were stored in the sdcard. Also the photo frame app i have on my homescreen often resets to nothing as the pictures were also stored in the sdcard. Its really annoying because I can leave my phone sleeping, only to wake it up realizing my ringtones are all set to silent and my photo frame has been reset. At least i know its a common problem. damn you samsung!
Has anyone actually tried checking the connection on the ribbon as suggested? Mine has been fine since and works fine.
Does this method void our warranty? Seems so.

There is no way anyone would know you have opened it, the screws are all Philips instead of t6. As long as you use the correct screwdriver it won't damage the heads and will leave no sign of entery and it takes around 10 mins to complete. Or you could take it to Samsung to do but seems a lot of hassle for such a simple fix.
Also most people are rooted without concern of the warranty.
So there's no seals or stickers that are broken?

Nope, no sticker or seals and just so you know all screws to remove the back are identical, there are only two screws inside which are different but do not need removing for this. You only need a Philips screwdriver ( I used a ph00 x 40) as long as the screwdriver fits the screw well it will not damage the head. Once screws are out a flat head screwdriver or similar are helpfull to prise the back off.
Hi Guys,
A little feedback from my experience with this.
I too was experiencing the "Unexpectedly Removed" error on my 32GB Class10 Sandisk.
It was playing havok with my setup because I use a 8GB Ext4 Partition on the card, where I move 90% of my apps. (About 6GB of that is used by games + their "external" data), and it keeps my phone and FAT32 partition free for important stuff. (I use Link2SD and DirectoryBind)
The problem is, after the device wakes, Link2SD can't find any of the apps, so I can't start any of them, and I have to do a full reboot to get them back. :/
So, after searching and searching, I couldnt find a valid solution.
I tried with a 16GB class10 Samsung, and a 32GB Class10 Samsung card. Exact same setup. NO ISSUES.
Everything works perfectly.
Then I found this thread:
http://forum.xda-developers.com/showthread.php?t=1933743&page=2
Where most of them are experiencing this error with Sandisk cards.
Apparently, it's a known issue with Sandisk Cards (especially the 32GB models), and cards sold after December 2012 no longer experience this.
I have contacted Amazon.co.uk about replacing the card as it's only 2 months old, still waiting for their answer. Will update if anyones interested.
cheers

A curious question if I may.
Was this a SanDisk Ultra (UHS) card? Most (if not all) Android phones do not have a proper UHS-I driver today and, although the card is supposed to switch down automatically, that transition time can fool the OS sometimes.

I read something about UHS compatibility, so I got an SD-HC
http://www.amazon.co.uk/gp/aw/d/B007JTKLEK/ref=mp_s_a_1?qid=1357264092&sr=8-7&pi=SL75
Is it the same thing?
Hmmm. Ok, might be getting somewhere.
Any idea if these cards have an internal "power saving" system that maybe kicks in if voltage drops below a certain level?

Yes, the red and Grey SanDisk cards are UHS.
Yes, they definitely have controllers and the host device can command them (if it knows how). I know that they allow In System Programming (ISP) for updating firmware. They support auto-standby, power-off and sleep modes but am not certain if the card would switch without command. Check the SD link in my signature if you really need more info.

I tested my SanDisk 64GB Ultra card in a Note 2 and it had the same symptoms (Mine were worse, with the card locking up while playing music after a few minutes, causing mmc timeout errors in the kernel).
I switched to a Samsung 64GB Pro card and since then I haven't had any issue. It's also twice as fast.
The amount of headaches this SanDisk card gave me is insane, probably the last time I buy a card from them.
i have sandisk ultra class 10 32gb. try this setup. use minitool to reformat your card then set it the cluster size to 16kb.
for me so far so good. will test this in a couple of days.
Hi,
Over the last week, I've had two SD cards die on me:
The first card I've had since I got my i9300 S3 (13 months). Prior to last week, it worked flawlessly (KomputerBay 32GB class 6). Then suddenly after rebooting I see an SD card damaged error. After trying chkdsk and fsck it looks like the card is certainly damaged but was able to recover some of the files.
Thinking it was just bad luck and the card dying, I purchased a 32gb class 10 Lexar card brand new. In the meantime, I used a 4GB Samsung SD card that came with the S3 for approximately 5 days and it worked fine with no errors or corruption.
With the new card, I copied over all my files, music etc. After an overnight using the phone, some calling etc. I rebooted the phone only to get the same error. Windows didn't even recognise the card let alone recover it. fsck likewise. Did a full format again and restored some files from original backup, it's been less than 24 hours and so far so good but I am not ready to relax just yet.
I'm really baffled as to what could be causing it as the card seems only to fail after a reboot. Prior to then, the card displays as mounted in system settings and files are accessible. The only other strange thing I've noticed is that when playing music/podcasts and turning off the screen the playback jitters for a moment or two before returning to normal. This started quite recently. I'm using UltimaROM 13.0 at the moment with Boeffla kernel. Have disabled all SD related optimisations and have no CPU or GPU overclocking or undervolting. I've been using Ultima for months with no major config changes recently.
I'm at the point now where I am almost scared to reboot! Last time I rebooted I unmounted the SD just in case. The only other possible difference in behaviour is that as I was travelling I had my phone on charge all night and although I can't be 100% sure rebooted with the phone charging (though again, its not the first time I've rebooted while charging). I've googled this far and wide and most SD related issues seem to be caused by the card randomly unmounting. I've never seen this in my instance.
Any ideas on what this might be or what I could do to troubleshoot further? I don't want to restore to stock, unroot, reset counters etc. and return to Samsung unless I can be at least reasonably confident its a hardware issue.
Thanks,

Do you mean http://forum.xda-developers.com/showthread.php?t=1906058 ? If so, yes though the key difference for me is that my card doesn't seem to randomly unmount like most reports indicate. Also, it's very recent. Don't also see any possible solutions in there unless I'm missing something?
