[SOLVED] Ubuntu 14.04 refuses to mount a particular flash drive

Ihatewindows522 · 02-03-2015, 07:30 AM

Recently I've been having trouble with one flash drive (Class 10 SD in a USB adapter) that I have, and only under Ubuntu. It will work normally under Fedora and Solaris, but for some reason, Ubuntu can't mount it. It used to work before, I don't get it.
Sometimes I get errors while formatting, but I couldn't manage to get one, and I know you can only write to these a certain amount of times, so I didn't pursue that too much further. And something funny about that, when I do get an error, it keeps formatting.

NOTE: If I put any other SD in the adapter, I get the exact same issue.

Below is a screenshot. Hope I'm clear enough. Thanks in advance for your help!

Please upgrade to current Ubuntu version for best support..

however the screenshot you provided tells you where to look for error messages that you will need to search on internet.

Personally i would try to check sd card with gparted.

"NOTE: If I put any other SD in the adapter, I get the exact same issue."

By this statement I'd say that some issue with the adapter and distro. Look at how Fedora uses the adapter and the driver for it.

I'd also consider a different adapter if you can't get this working.

Exactly how does adapter connect to system?

In all this stuff, various programmable chips inside the system and various coded timings and even acpi and such can have enough of an impact to cause issues.

I would perhaps start by looking what does the kernel tell. Can you insert the card, wait a few seconds, and then post the output of "dmesg|tail -20"?

Best answer !

The issue seems to be related to

Quote:

[ 40.902715] FAT-fs (sdc1): Unrecognized mount option "x-gvfs-show" or missing value

There are many links on the web, for instance http://http://askubuntu.com/question...mount-on-12-10 and http://http://ubuntu.aspcode.net/vie...fs-show-option.

Briefly, the issue seems that the file system and certain icons cannot talk well together. There are also suggested workarounds, as I don't have the problem (and don't use unity), I cannot really try those.

Looks like a bug...

First of all, thanks for your help this far. Unfortunately I had to reinstall Linux on this partition...twice. The first time was with Manjaro just to find out that there's a bug that I found that I remember from the early 2000s that happened with Mandrake. It refused to mount the root filesystem it just made. So...back to the Fedora/Ubuntu combination...I'll make it work.
