Description Robert Wallace 2012-06-04 18:06:16 CEST

Description of problem: I am unable to write to a 2GB backup drive, but can copy a file from the backup to the hard drive. This backup drive seems to be locked in some way (read-only) that chmod is unable to modify. Reading permissions with the Dolphin program finds the user permissions in place, but nothing for group or others. Attempting to change with chmod in user (me) or root makes no difference, the same "failed to change" message coming up for user or root.


Version-Release number of selected component (if applicable): Dolphin program running under Mageia 2.


How reproducible: Continuous over a number of days now.


Steps to Reproduce: chmod 750 /media/68BA-AABE__ -v

This command line should change the backup drive to allow for Read, Write and Execute, but error message keeps coming up with "failed to change" the device. Is there some other way outside of chmod to change the setup for this backup drive to allow writing to that backup drive?  (This problem has also been reported to bugs.kde.org)

What is the filesystem used on this drive ?

Sorry. FAT file system.

FAT doesn't have permissions, so chmod will not work on fat filesystems.

But you can change default permissions on all files using mount options when mounting the device.
