Question USB Drive mounted in rw mode but acts as if read only

Hi

I have a USB drive that is mounted in rw mode

Code:
/dev/sdc1 on /media/disk type vfat (rw,nosuid,nodev,uhelper=hal,shortname=lower,uid=501)
However when I try to delete something from disk it reports
can not delete - read only filesystem.

How can it be?

Thanks in advance.

Regards

Hello:
Odd ... ?
Can you copy a file to the drive, and if so, can you then delete it?

Also, try
polkit-gnome-authorization
and see if there is any setting there that doesn't make sense.

I can not copy or create file on disk.
It acts as if it is read only.

I'm not familiar with this application,

I think you can see in /var/log/messages file for any output when you connect the drive. Just connect it and as root type:

tail -n20 /var/log/messages

Thank you - you saved me!

It was very silly of me not to look at messages at first.

The problem was that fat table was corrupted
log says:
Code:
FAT: Filesystem panic (dev sda1)
invalid access to FAT (entry 0×00c63d67)
File system has been set read-only
fsck.msdos -a -v /dev/sdc1
saved the problem

Regards.
