Have you tried pulling the sd card out. putting it into your computer with a usb adapter or similar , backing up the contents, then formatting it? then reinsert into your phone

 

it sounds like there is something wrong with your sd card. If mint was not reading it at some point...that's a pretty good sign. I would backup (if possible) and replace.

 

no clue but i wouldn't trust it lol

 

im gonna guess that you either A broke something in system or B the more likely explaination, it was accessing the sd card when your phone restarted, ever so slightly corrupting the file system, making android itself able to recognize there is a problem because its much more picky than cwm. that is why there is an unmount feature for sd cards, they are easily corruptible if you dont eject them properly and wait till they are "safe to remove"

 

If cwm reads your card then its good, I never got Linux to mount my sdcard as I didn't set it up to mount mtp devices yet so the only way to mount in Linux was to reboot cwm and mount USB storage, but that's for me idk might be the same for you. Anyway I've ran into my fair shares of sdcards problem from 2.3 GB to 4.1 JB. What fixed it? Simply manually removing the sdcard from the phone and put it back in. Kept doing that until it finally mounted it lol takes about 3 or 4 times to get it. Have you tried mounting in windows? Like junkie said cwm isn't too picky when it comes to mounting the sdcard but try mounting it in a different operating system other than Linux. If it mounts anywhere else its still good. Other android devices will work too. If you have an old one sitting around try to see if it will mount the card, Good luck.

 

i got a little confused. I thought he was saying he put the sdcard in linux mint and it did not recognize it. I have been a linux user for a long time and never met an sdcard that wouldn't mount. Now that i understand better, i agree with them lol.

 

well, cwm being able to access it doesnt mean that it doesnt have a problem, it merely means that it doesnt have a big enough problem to cause complete failure. youll notice when android boots up or when you insert a card it checks it for errors, cwm doesnt do that sort of thing

basically, android is very picky about reading sd cards, cwm is more like your average simple device, if it can manage to access it it will even if all it end up showing you is 32gb of corrupt data

 

well, ive seen a few that windows refused to read, but could be accessed fine in simpler devices. the more advanced the device the more it tends to complain about file system errors, and id say a computer is top of the food chain. you pop it in a cheap no name brand mp3 player i bet you itll work just fine kuz that isnt going to check the file system its just gonna try to read it the best it can

 

its unlikely that ALL of the data on the card will be corrupt, though some of it might. it may even be the rom is messed up so you might wanna try reinstalling a fresh copy of a rom just to be sure, other than that the only thing i can suggest is reformatting the card like i said before. if you can get your hands on another sd, maybe some 2gb that came in an old phone or something, that would tell you whether its the card or the device that is the problem. even borrowing one from someone elses phone momentarily would be helpful

 

Have you tried gparted on mint? It is a great partition editing tool and it recognizes unmounted drives. Not sure if it is installed by default but that's easy enough

Code (Text):

1. sudo apt-get install gparted

 

np. and superr just for reference mint and ubuntu dont come with gparted in the installed version its only in the live version to my knowledge, you can easily download it though as you said through apt-get or it can be found in the software installer
