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.

yeah, fortunately I had done this about a month ago
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.

SD-Card Error - Round 2

Hey guys,
a few month ago, i created 2 threads here.
My sd-card simply stopped working and I couldnt find the issue, even replacing the slot did not help.
Today, suddenly, my bootloader recognized the card with a PC10IMG, just tried this one out.
I could upgrade, got to the newest radio, and android 2.3 (Virtous Sense 2) could use the sdcard.
But at first, wlan did not work, so i restarted the phone.
Now everything seems fine, except that after a few seconds, the SD-Card is "unexpectedly removed". or "damaged". I cannot format the card using the phone, even in recovery menu its unmountable after a few seconds. Example: I chose "install zip from sdcard", could find the rom on it, but when it started installing, the installation immediately aborted and after this, the sdcard wont answer anymore in any way. This is reproducable by simply formating the card again using the computer.
Any ideas how to fix this?
Thx in advance..

Its possible the connections for the sd card slot are damaged or that you got a damaged replacement, or that you might have damaged it on installation. I'm leaning towards the connection on the main board being damaged in some way. it's strange that it is intermittent.

I dont think its a problem with our memory cards. Either the card slot that Samsung made is of very poor quality or it is a problem with the latest ICS firmware. There A LOT of people facing this problem out there including my cousin who is the only other person i know with an S3. Not only does his memory card slot disconnect and reconnect, it completely killed it, it does work anymore. In some situations online, i have seen that people have ruined 2-3 memory cards by putting it in the S3.
I am facing the same problem and it is getting on my nerves. I live in a third world country so I might not receive a new phone.
Please find a solution XDA FORUM! :crying:

Had the same issue with my S3.
Turned out that the SD card was dying (the card brand is Team Group), this caused it to be unmounted by itself and then mounted again (sometimes showing notification “sd card removed unexpectedly”), hence triggering the “Media” scanning process and significantly draining the battery.
I created an application to monitor how many times the SD card was removed, and turned out to be unmounted every ~3 mins!!!
I then bought a new Transcend 32GB Class 10 card (made in Korea), and until now, this never happens, no reports from the application whatsoever, and no media process eating my battery.
I just published this app in the play store now, this is the link:
https://play.google.com/store/apps/details?id=com.sdcardmonitor

sd card unmounted/removed unexpectedly!

Hi friends, Im using 64gb class 10 sandisk sd card. So after updating to lollipop i have been getting these errors frequently and i have to restart the handset to fix it temporarily. I had this issue on kitkat as well but happened only rarely like once a month or so.
These two things happened unfortunately,
1) i had dropped my phone on carpet from 2 feet after lollipop update. I wonder if the phone couldn't handle it!
2) i removed the sd card without unmounting it from settings and immediately got the error and kept happening after that.
so i am confused what caused the issue. Is the connector loose or what is the problem. this is very annoying!
I have formated sd card, reset handset and tried another sd card and still the same issue. sd card is detected on the pc. Happens with transcend sd card as well. Please advise i am confused. do i take it to the service center. will they find out if it was a physical damage?

In my experience that happens when cards start to go bad. Maybe once to often of removing without unmounting first?

yes i did remove the sd card a couple of time without unmounting, however as i said that even my 8gb trancend card threw the same error... im gonna try another 64gb card and see the result.. still more replies would be appreciated

so i noticed that the issue kept happening even with 3 different sd cards in the phone. Surprisingly the error also popped up without the sd card. I am assuming this is an issue with lollipop software? can someone please shed some light on this ****!

Do a factory reset. Lollipop has no such issue.

LG G3 Not recognizing any SD cards, Sometimes says i dont have my SIM insterted

Hello everyone so i have around 3 months since my phone stopped recognizing my SD card I've tried numerous file explorers on that play store and none recognize my SD card, and when i go to TWRP it says i dont have an external storage. Ive also tried other SD cards of good quality so i do not think that my phone is being picky with SD cards, it just stopped reading it out of the blue. I am running on Bliss Pop rom and did a factory reset but my SD card is still not being read, the rom shouldnt be a problem, right?
Recently, maybe in the past 2 weeks i started getting problems with my sim card and getting a message that says something along the lines of "No sim card inserted" message. i sometimes fix this by rebooting my phone but today the reboots did nothing for me in a span of 3-5 hours.
Since the SD card slot is above the sim card slot, is it possible that i have a hardware issue on my phone?
Any ideas as to what may be wrong with my phone?
I have an secondary battery and i got in the habit of doing battery pulls could that have had anything to do with my problems?(Seems dumb but i am just throwing this out there)
Thanks for any input i get
