SD card keeps unmounting

[mrbubba999]

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.
