SD card woes

Hi,
Seen various SD card problems posted here and other forums but no solutions.
A few nights ago I was transferring a large number of files to my Desire and noticed the transfer windows froze so I disconnected my phone. When I then tried to turn the screen on it wouldn't turn on (though the led kept blinking). I eventually had to restart the phone by removing the battery.
Upon restarting I got an error saying the SD card was corrupted and needed to be formatted. Tried restarting again etc but didn't work so clicked on 'format' in the pop-up but nothing happened even after several attempts. Then tried doing this through the settings menu but again didn't work.
Gave up. Wake up next morning and phone screen won't come on again. Took out battery again and still had memory card problem so connected to pc and formatted card on there. I think after this the card started working again but WITH ALL THE DATA STILL ON IT. No idea how!?
This morning after 4 days working fine I connect phone to pc to transfer music and don't get an option to mount USB so I unplugged and get a new SD card error: blank SD card. SD card blank or has unsupported file system. So tried everything I tried last time but this time I can't mount the card so I can't access it on a pc to format it.
Anyone had similar problems on here? Seems to have happened to quite a few on Android forums etc. Any suggestions? Have tried putting card in and out several times. Have tried SD mount widget. Getting pretty desperate here.

had exactly the same issue you had the second time, posted, found no fix.
Using a spare sd card I had in it's place, my phone registered it as blank again the next day! It was a reboot job though and it has been fine since..
Would like to get to the bottom of this before a blow a decent sized card

I have had many many bizzare and quite frankly random SD card errors with this phone. Nearly one everyday doing something. Most of them read the same SD card missing, needs formatting, is empty or corrupted notifications. The latest one occurred 5 mins back on reinstalling NewsRoom app -- suddenly left with a totally empty SD card when trying to save RSS to it. As in every case, an immediate reboot fixed the error so I can't offer any more help.
Whenever I've had the "needs formatting" error I removed the card for a few mins before replacing it back inand it worked fine thereafter.

I've just tried leaving the card out for a few minutes with the phone off and reinserting to no avail. Tried restarting lots of times
Going to try another SD card now. Most people on other forums had problems with their stock 4gb cards whereas mine is an 8GB card i got separately. I think it's the phone at fault not the cards.
**Update** The other SD card is working fine so far. But i'm now left with a screwed up 8gb card that's not recognised by any pc. Any suggestions of how to fix this?
If my 4gb card is screwed up by the phone too i'll let you all know

SD card unexpectedly removed...

So I have searched for this error and no one seems to have an answer that fits my problem. I got an error after booting that stated SD card unexpectedly removed and gave me a triangle with an exclamation point in the center
the card works fine
it will mount up perfectly from recovery, i even pushed several roms to it and tried (cyanogen, RR, and SkyRaider) all three worked beautifully, but as soon as I boot up BAM "SD card unexpectedly removed" and I can't access anything
the computer reads it just fine so I am pretty sure there is nothing wrong with the card, also with it reading in recovery it seems there is nothing wrong with the phone
is this a problem with ROMs?
I could try to do a factory reset and see if that works... but its really annoying :\
any help?

I would try reformatting the card on your PC. The card may have a bad sector that the PC and Recovery ignore. The phone OS tends to be a little more picky about those sort of things.

This worked
Thank you, I am running good now
I noticed when I was trying to backup my SD card (pictures and whatnot) that some of the files were corrupt
I will make sure I keep a regular backup just in case its a sign of the card going bad
good thing is my titanium backups were all perfect

You are on the right path - don't forget, a good practice is to back up your SD card to your PC regularly.
Why? If (when really) the SD goes wonky, you have a PC backup of the card, and you can get another SD, format it on the PC, load the backups you made, and be back in business in short order.

I lost a few pictures that I took recently but overall it wasnt a big loss
I will def be doing this more frequently

Same problem with a twist
I receive the same error only i can't get anything to read the card after it happens. Any help would be appreciated.

My solution was to format and start over, that was the only thing that worked for me

I've gotten this a few times and it is a PITA because it resets all the notification sounds and also the phone reboots. Once it does it, the only way I can get it to work is to remove the card, put it in the PC, let Win7 do a fix and repair errors and then it will work. I tried removing and reinserting, and it would mount the card and immediately give me the 'sd card unexpectedly removed' message.
I tried reformatting, and the sd card worked for a while and then I got the 'unexpectedly removed" message again after a few days. The last time it gave me that message, I just did the repair errors thing again and it's been working without fail for about 4 days now. It seems like it's going to be an ongoing thing though.
I've been googling like a mad person trying to find a real fix for this. I saw a thread on Android central where they guy said he put his wife's card in his phone and it did the same thing; but worked fine in hers. He mentioned it might be related to the 2.2 OTA update. My problem did start after that update.
In another forum thread, someone posted that they bought a new card, and it gave them the same message. So it doesn't appear to be a bad card; which is what I originally thought. I'd hate to buy a new one and have same issue (i have a 16gb card currently).
(sorry for long post)

I have the same problem! I'm using a Verizon HTC Droid Incredible 2. Previously i've been running Froyo 2.2 over the phone with a 16 GB microSD Card without problem. Later i've been using a 2 GB microSD Card and works fine, but now i'm runnin' Gingerbread ROM From verizon with 16 GB microSD Card and the messages "SD Card unexpectedly removed" don't stop.... the card works fine over other phones... even the stereo of my car can read perfectly the card's content.
I don't know if this is a problem with the update or what????
I don't think in the versions of "Bad sectors" because i check everthing and the problem persist.
The problem appears when i'm playing music... later of that the problem appears at the camera, the file explorer or another app that tries to read the SD Card.
I reboot the phone and works fine but after a couple of minutes the same [email protected]$%&t appears again....
I'm tired of reading forums telling me that is a problem with the sectors... that is a LIE!
no matters the class of the card because i've tried with Class 2, Class 4 and works fine.
This night i'll go to the store that solds me that coursed card to change it!
if tomorrow my problem was solved i been writing at this same forum!

I do not think someone saying it is bad sectors means they are lying.
I think they are merely trying to help you determine what the problem could possibly be.

did you format the card and try again as suggested earlier? That usually clears up any issues with sd cards unless they're fubar'd. Just make sure you back your card up first.

Whenever my card does this I put it into my Windows computer, right click on the card and go to properties/tools/error checking/ and check both boxes and let it run. It fixes my issues every time without formatting the card.

I had that problem a while back with one of Verizon's updates after 2.2. Reformatted card. worked fine in other phones but still said same thing everytine I put it back in the dinc. Ended up getting a new SD card then all was fine.

If you have an ext extension on your sd use G-Parted (google it) to format your ext2/3/4 partition.

[Q] Micro SD not detected

This morning, my phone was normal. Using apps, making calls, no problems.
Then I noticed my ring tones and my notification tones wouldn't play. Since they are stored on the Micro SD card, I thought a reboot might solve the problem. After rebooting, I get the message "SD Card Damaged". So I took it out from my phone, plugged it into the computer through a USB MicroSD reader. It detects it, and from there I can see all the files stored on there.
I decided to run a Windows (7) error check test, as that usually fixes any sort of SD problem I've had. The check ran through successfully, saying it found some problems and fixed them. After that, I put it back in the phone, boot it up, but it still wouldn't access the card. Most of my apps are stored on there, so I wanted it fixed. I took out the card and ran it through windows error check once more, only this time, I checked the box "Scan for and attempt recovery of bad sectors" and hit start. Two hours later, I notice the progress bar hasn't budged from what I can only assume was 60-65%. I decided to hit "cancel" and look up some alternative methods.
Except as soon as I hit "Cancel", something went terribly wrong. The computer no longer acknowledged I had a MicroSD card inserted. I removed the USB adapter, removed the mSD, reinserted the mSD into the USB adapter, replugged the adapter in and -- same result. I restarted the computer, and while that cycle started, I placed the card back into the phone to see if it would detect it. No luck. By this time, the computer had restarted, and I tried to reinsert the card. It detects the USB Adapter, but it's as though there was no card inserted.
At this time, I scoured the web and countless forums (including these @ xda) with no avail. I tried nearly 10 different applications built solely for data extraction, but they all had the same problem: they couldn't detect the MicroSD card. My fellow I.T. coworker suggested using an Ubuntu Live CD and try their diagnostic tools; it couldn't detect it either.
Here are the specs of my setup:
Phone: HTC Desire CDMA (USCC)
Rom: Phoenix 1.4 BravoC
Card: Samsung 8GB Class 2 MicroSD (stock from US Celluar)​At this point, all I'm really concerned about it just retrieving my lost data. I have important sentimental photos, and more importantly, I have important flash backups from my stock rom that I would need if I want to return my phone for warranty. Physically, the card is undamaged. No dust, no cracks, no wear & tear. Hours of googling "SD card not detected; data recovery" leads me to several unanswered problems and fake websites baiting computer illiterate people into downloading malicious software.
I've heard of solutions that involve sending a card in to have repaired, but in turn, shelling out a couple hundred. Now I'm not stupid when it comes to computers, but I'm not necessarily a genius either. I've tried several ways to circumvent this lockout issue, and I can't find any way to undo a process from the Windows error checker. Hell, I can't find any cases or threads pertaining to people having bigger problems because of the error checker.
So I call out to anyone who can help. I can buy a new card, no problem. I just need my data back. It's crucial for my phone and important for me and my memories.
Any suggestions?

Hi
My phone:
Disire HD (GSM)
Android 2.3.3
CyanogenMod 7.0.0 RC2
I had the same problem as you a few weeks ago(my phone wasn't rooted) ....
Tried different methodes to get my data back, they all didn't work.
The problem is not the phone or any app on it neither your roms are the problem,
searched the internet... and came to the solution that I was not alone with this problem. they assume this is an hardware fould in the SD card ( btw its weird that its an Samsung SD, didn't you thought the same I still dont understand...)
Anyway, my solution was going back to the shop where I got the phone (Belcompany NL) and ask there solution for the problem i lost all my pics and other importand crap haha..
They didn't had a solution or something, just giving me a new one.. so I got a new SD Card (for free )
But lost all my data

You know if a partition messes up, which it has done because you didn't let it finish, there is like 0% chance that you can recover any data on your SD card. You should of backed your card up before you attempted to even start doing a disk check. As for getting your SD back up and running, you can try gparted live cd and see if it will detect it in that. If so just repartition it, but next time, let it do a thorough disk check and finish. Checks can take hours and hours because it is doing something. Just backup your SD card frequently.

I've decided to purchase a new card rather than hassle with unrooting my phone for the sake of going back to the USCellular repair (on just a whim that they may replace the card).
I've heard that I need to be careful when choosing a brand of MicroSD cards. Transcend is a no go. But what about this: An 8GB A-DATA Class 6 MicroSD card?
From what I've gathered, A-DATA is a reputable brand, and it shouldn't really cause problems in my HTC Desire, right?

[SOLVED] SD Card "Damaged" after N7105ZHUENA1 update

I have an N7105 which has been running the N7105ZHUEMK3 software with no problem.
Today, I received the new N7105ZHUENA1 update over the air.
After installing this update, the phone can no longer read my exFAT format SD card.
I get "SD Card Damaged" and "SD Card Blank" messages after every reboot. Manually attempting to mount the card via Settings causes the phone to hang for a period of time, then report the same errors.
The card is not damaged: My other phones, and my PCs (with an adapter) can all read the card with no problem whatsoever.
This feels like something related to today's update.
Redownloading and applying MK3 didn't solve it - it made things worse in fact - I ended up going forward to NA1 again.
After working on this all day, the only thing that appears to have solved this is to pull the battery, insert a DIFFERENT, blank, SD card in the phone, let the phone boot, come all the way up, and settle... then pull the battery again, reinsert the original SD card (which, again, worked everywhere else), and let the phone boot again. Now my original card is back, fully readable, and working again.
I had removed/reinserted/rebooted the same card numerous times today, and it came back damaged (only by my note 2) every time. Only inserting the different card temporarily seems to have "broken the pattern" and made everything okay again.
I have no idea what caused this, or why that step fixed it, but I'm leaving this here in case anyone else has this problem.

SD Card issue: SD Card Unexpectedly Removed

Several weeks ago my G3 started to throw errors "SD Card Unexpectedly Removed", and then phone is trying to mount sd card back.
I have already tried: reformat my sd card, brand new sd card, stock firmware (4,5 and6) none of these helped.
Also it doesn't look like hardware issue: i put sd card the other day and everything worked fine for a whole day, no error messages. And then it came back. Reinserted card could work for a day , or could begin push errors immediately.
Any thoughts how to fix ?
(sorry for broken english)

I have a t-mo G3 D851 that does the same thing. With stock MM, it was doing it randomly, as you seem to describe happening in your case. After flashing Fulmics, it seems to happen only after a reboot or a cold start from power off. I am suspecting that it's a hardware issue. Bought it "new" as a store demo device.
