Today I needed to repair an SD card which mounted "read only". I installed gnome-disk-utility from the repo and...

It looks different (e.g. has a play / pause button for mounting / unmounting a partition) plus a right click menu. But the options are limited. There are no separate items like "format volume", "format drive" and -- the most important -- "check filesystem". The version is 3.x.x

I had to roll back my repo to 12.04 and install the 2.x.x version. Luckilly, it worked.

Does anybody know what is happenning? Are the missing functions taken over by some other program or utility?
