Can't delete/edit files on my pendrive
If I were to guess it sounds to me like your Pendrive is corrupted.
the simple solution is to back-up and reformat however if you want to find out if it is really corrupted or not which could be a sign of a failing flash drive use fsck
first back-up your pendrive/card then find out what mount point its under eg. /dev/sdb , /dev/sdc etc.
You can find this information in disk utility under the heading Device:
in the screen shot it is /dev/sdb1
You can then modify these commands and run each
sudo umount /media/disk
sudo fsck -favVr /dev/sdb1
Alternatively you can click "check file system" after unmounting the drive in disk utility
Edit:
I have found another solution to this problem the steps are as follows
- Mount the USB Drive you are having the problem with
- Open Disk Utility as root open a terminal and enter
gksu palimpsest - Unmount the Drive and remove
- Plug it back in
Hopefully this will work if all else has failed
