Tonight I have been having problems with my SD card, anytime I try and download a file to it, I get the error "SD card unexpectedly removed" and then I can't access the SD card at all until I reboot
Any help appreciated. I'm running miui freshly squeezed with a class 10, 16 GB card

Back up everything you have in your SD card.
I had that same symptom once. After a few reboot I lost the SD card. It became unreadable/unformatted.
So, just in case. Back up your data first.

Cheers, done a bit more digging and its an issue for quite a lot of people. Backed up the card and using the standard 8gb that came with the phone. Ordered a new one too from play.com, as they are in the sale

I had the same problem unexpectedly too the other night. I took the SD card and via a usb adaptor I connected it to my Windows 7 computer. A window popped up asking if I want to scan and fix for errors or continue without scanning. I usually just continued without scanning when connecting my phone directly but this time I let it scan and fix. Low and behold once it finished the scan I tried it again in my phone and it mounted successfully. Ever since then I've had no further problems since either.

This happened to my 16gb mmc. Went on for a couple of months. I ignored it and mounted it manually. It died a couple weeks ago. I had no back up. Devo

Yup, same happened to me, lost everything on the memory card (though I had backups of the important stuff)
Same Problem
Guys i have been experiencing the same problem for some days now.
Found this post here; Was thinking the problem has been solved over here, but you all are reporting your problem.
Any there anyway this problem can be fixed or as most of you mention. The lifespan of the card is getting close.
Or I should just prepare for a new sd card (which am not ready for now).
My Case here is kindda different because when i boot into recovery, the sd card shows up and works fine.
when i boot into android then it cant be found.
???
i have same problem with android 4.0.4 and sense 4+
i must be reset my phonee
my phone is HTC Desire 268. now for a little while my sd card did have a problem when i first brought it but it was fine afterwords but today after I restarted my phone, my phone again is getting problem with sd card the sd card mounts for a little time than it unmount ( giving the status "SD card unexpectedly removed"), then mount it self again and unmounts itself again. this happens 3 to 4 times before it competently unmounts and never mounts until i remove and add the sd card again and the cycle countinues. please can you help me.??

When I tried to access an app that was installed on SD, my phone locked up. Upon a reboot I no longer have access to the card, all the apps' shortcuts are broken and all the options like mount SD card, format SD card are greyed out. Also when I connect the use cable there is no option to mount as disk drive anymore. I've rebooted, tried removing the card etc but no luck. Anyone else had this? I can't find my micro SD card adapter right now so I cart try it in my pc.

Did you try running checkdisk from windows to repair it?
No cos I can't mount it in Windows

Try repartitioning your sd card. Could be a corrupt ext partition, or your sd is completely screwed.

Sounds like a bigger problem than a broken ext if nothing can read/mount the sd card. Might be the end of your sd cards life im afraid

I've only had it about 2 months.....get what you pay for I suppose (click). Anyway still no luck with the adapter so I'll see if anyone's got one at work tomorrow.
OK, I found my adapter (and my old microSD card hiding within), windows has no problems seeing the 16gb card and my old (original 4gb) card has the same problem in the phone. For good measure I did a chkdsk on the card.
What are my options?
I've performed a full reset and still got the problem. Anyone got any suggestions?
anyone? I'm thinking it's a desire hardware fault.
any help? cheers
A number of us have had failed SD cards. In my case, Windows could see it well enough to copy most of the data off but failed to reformat it. I suggest you try to copy the data somewhere safe and then reformat in Windows. If the reformat works it's probably a hardware issue. If the reformat doesn't work it's probably the card.
I'm sure others will have different views!
Yeah but it's same with both my cards. I'll give it a go anyway cheers.
The one that came with the phone .. ( 8GB Class 2 ) came up with with a read only error last week ...
The card was dead.
I got a 8GB card class 6... used app brain .. and restored all my apps fine... etc
fab.. phones faster .. no problems
After inserting my old card again I now get the dreaded -
SD card damaged. You may have to reformat it.
Of course when you follow the wizard to format it, it doesn't seem to format it. I did try a full format in Windows earlier, no luck.

Just to help anyone who stumbles over this thread in search of an answer, I've had to send it away for repair, it appears to be a hardware fault. 2-3 weeks.

SD card unmounted without you doing anything? What did you do before you encounter such problem? I experience it before.. when after flashing a ROM.. and it occurs.
But as I know flashing ROM can corrupt the SD card. So you may consider to format it.(of course save all the necessary files in it first)
a failing sd card will also cause this, i had a 16gb give up the ghost last week, only realised when i took the card out and put it directly into my computer and it kept un mounting.
It doesn't have to be a bad SD-card though. Android is pretty picky, so even some bad files or something similar might be the cause.
I had the same problem and for me (not everyone though) reforming the card on the pc fixed it.
im using the ota rom as i have not root it.. it failed 5 times in a row today... after restarting the 6th time it worked...

Hey,
So ive been having some problems since i got my T989 in november. About once a month my SD card just seems to fail... like just now, i rebooted the phone (power off then on) and it comes up with "SD card is Damaged" Why is this happening? its getting really frustrating because i like to do all my nandriod backups onto the SD card...
Anyone got any advice? Could the card be faulty? The other times it was basically doing the same thing. Eject the sd card properly, remove it, plug it back in... Failed!... ugghhh.
Sounds like it is just that...sd card is faulty. They are so cheap that I'm not sure why you don't just buy a new one?

When I turn on my sgs2 this morning, I suddenly get this message:
damaged sd card
you may have to reformat it.
why is that? what caused it?
does anyone know?
because there is nothing wrong last night when I turn it off.
is it possible to fix it without reformatting it ?
I hate losing all those datas.
my sd card is transcend class 10 16gb, I have used it for only 3 months with no problem at all.
I have tried reboot several times, take it out, clean it and insert it again,
but nothing works.
Please help.
My rom: wanamlite v6.7
My kernel: Phenomenal Black v2.1
Try putting it into your computer and see if it opens. Also, windows may offer to fix it (which shouldn't reformat it).
Either way if you can get it to open on a laptop or something even for a bit you should be able to save your data.
Freezer trick (like for fried harddrives) might also work.

Why did u buy transcend sd card?i am using Kingston 16 gb class 4 card and i think it gives the best performance.Class 10 sd card should perform better than class 4.You may consider sandisk as second option.I am sure u are gonna lose ur data.
Hi Guys,
thanks for all the advices.
when first I connected the sd card to windows, windows could read the directory.
however, if I click on the file, it gave error message: file not found.
then, after did some searching on xda, I found more similar thread like this.
and some told me to run window error checking and chkdsk /r.
the problem is, it seems that every time I run these program, the sd card is getting harder to read.
then, I run them again and again, finally the sd card now can not be read at all.
Too bad, I guess it is time to reformat.
PS. I should do more reading and searching before I run chkdsk:

Hello, I am on an HTC One V running PACman ROM 15.3, with the kernel JmzPrimoC+.
I started having this problem a couple weeks ago. It would randomly unmount my SD card saying 'SD card unexpectedly removed'.
This started to happen more and more often until it would say that as soon as I put the SD card in.
I did a factory reset, which helped for about 5 minutes before it started happening again. Now, more recently, it started saying 'Damaged SD card. SD card is damaged. Try reformatting it.'
I put it in my computer (which doesn't show anything wrong with it), and did a full format. It didn't help at all.
This problem is happening with both my regularly used SD card (SanDisk Ultra® microSDHC™ UHS-I 32 GB (the red and grey one)), and my ordinary SD card (8 GB class 4 Kingston).
I don't think this can be a hardware problem because when I boot to recovery, TWRP recognizes it perfectly.
But I don't either see how its a software problem, because a factory reset should have helped...
Please help me, any help will be greatly appreciated.
Maybe its a bug in the rom?

Hhmmm...
Good idea. What other ROMs work with JmzPrimoC+ kernel? AOKP?
Sent from my One V using xda app-developers app
OK, update, now TWRP won't read the card! Either card!
Now I'm getting really nervous...
Does this mean it must be hardware?
Is there ANYTHING I can do now?
Please help!
Wow, I screwed up really bad.
I was gonna use TWRP to flash a new rom, so I did a factory reset, and then started flashing the rom.
But in middle of flashing the rom it was interrupted. So I rebooted, rereset, and then I realized... it's not reading my card.
I can boot to bootloader and recovery, but that's it. No OS. I'm screwed.
Is there ANYTHING I can do?
Is it possible to flash a rom over USB? Or SOMEHOW get my card working again?
Just enter recovery and use adb sideload to flash a ROM.

But I need an SD card in order to use ADB sideload!
It fails every time because
Code:
E:Unable to mount /sdcard
Is there ANY way to do this without an SD card?
OK, I was able to do it following this guide.
I flashed the latest version of PACman. Still rejecting my SD card though.
I guess it's a hardware issue. Too bad my warranty is void from bootloader unlock :\
Try to partition SD Card in recovery
I am facing same issue and I came across this thread while looking for solution. Here is what I tried. That resolved issue for five minutes and then damn! same issue again but someone can find possible fix using the info here.
HTC One V rooted, currently running MIUI 3.1.2 with JB 4.1.2
Sandisk 8 GB SD Card.
Firmware CWM Recovery
I was facing same issue even before I rooted my phone while Original HTC ICS 4.0 Firmware was installed. MY observation is the problem starts few months after you start using SD Card. (Insert a new SD card in your phone, it will work fine for days / months and then will start giving same error.
While I tried thousand time to remove SD card, clean slot, clean card and reinsert, it did not work. May be worked just once for few seconds. When I tried to connect phone to PC and browse SD card contents, the card was not detected.
Booted to recovery, tried to format card, not detected. Tried to mount SD card, not detected. Then tried to partition SD card in Advanced options in recovery. The available options are 128MB, 256MB, 512MB, 1024MB, 2048MB and 4096MB. Since my SD card is 8 GB, chose the largest option. Now got an option to choose SWAP partition size. Chose 256 MB. Next chose option fix permissions, you have to wait until you see message permissions fixed message on screen.
Now rebooted phone, and voila! It worked!! SD card with 3.94GB memory is detected. But what happened to my rest of 4 GB?
Tried many apps to manage SD card from Play store. Using an app called APart, was able to delete partitions on SD card and create new ones. It worked for few minutes and then again I got SD card unexpectedly removed message.
Does this info makes any sense? I am not a developer and do not know much into phones but someone who know might be able to help. Buying a new SD card is not an option here because its going to work temporarily.
Have you tried formatting the SD card with your computer?

Yes, tried formatting SD Card using computer. Works fine when connected using adapter. Not detected when phone is connected to computer.
Been working fine for over a month now all of a sudden the SD card appears to be randomly mounting/unmounting itself and has become unreadable on my phone.
I've put the SD card in my PC and it works fine so I suspect my phone has developed a fault. I hope I don't have to get an exchange as it's otherwise faultless and I'm dreading getting a unit that can't be S-Off'd
I haven't modified or installed anything prior to the fault developing,
Any tips would be most welcome.
PS It's a genuine Transcend Premium 300x 64GB bought from MyMemory.

well, a simple solution is to enter recovery and see if the sdcard works there if this way it works, change the rom/perform factory reset, if this doesn't, well, you might try to flash everything again, but i's possible that the sd slot is broken...
i wish you all the luck, let me know
I would copy EVERYTHING off the card to a PC and do a format and try a different file system. I would has perform the format on the phone, to make sure its gets formatted to the correct file systems.
Long story short, It sounds like you memory card is starting to get Corrupted. I have to SanDisk cards that started doing that in the biginning and ended up not being read at all on PC nor the Phone.
Also while its doing that, youll also notice the battery start to drain more, at leasst thats what happended on my Note 3 when I had the san disk cards going corrupt.
Ended up buying new Card and now everything is fine.
I doubt is the card reader built in phone, more then likely its your memory card going corrupt.

I agree most likely the card. I'd download an sd card format tool and do a full format, don't use Windows format then do full check for bad sectors. I had a similar problem and it was the card at fault, but strangely worked ok on the pc.

I have been through many a Samsung phones and always had corrupt sd cards in exfat. One day I saw a thread that said convert to fat32 and have never had a problem since.

Thanks for all the advice.
I could read the card in recovery but it failed to format there.
I tried to format in windows but my only options were NTFS or exFAT, no FAT32. But this failed anyway also.
Downloaded a SD format application but this said the card was write protected and to move the lock switch, obviously MicroSD has no switch like standard SD.
So next I deleted all the files on the card and ran h2testw test. This failed and reported card is probably faulty.
Then I checked the contents of the card again and all the original files were back again, so it's definitely 'Donald Ducked'. I was able to get all my files backed up and fortunately I had my photos already thanks to Dropbox & G+.
So I will now look at getting MyMemory to replace it but my fear is they will want me to return the faulty card but it has sensitive information on it that I can't delete. Any ideas on how I can wipe it?

How did you attach the card to the pc? Try a usb card reader and then try again. If still problems download mini partition tool (Google) and delete the partition. You can then wipe it properly.
I reformatted the SD card from the settings within the phone and since then it been working fine :\
make sure you're using 2.0USB also..
when i connect my phone to charger
Its been few days i am noticing when i conmect my phone to charger it says 'sd card removed unexpectedly or either it suddenly stops showing content from my phone, then i have to go to settings unmount/mount the sd card frkm storage option and then it shows the content even when charging, or sometjmes it doesn'fshow option for that so on that case i have to restart my phone. What could be the possible reason and solution to that. It was fine on 4.4.4 now i am on 5.0.2 all stock htc one m8 h/k edition with sim unlock and s-off via sunshine.
