Sudo let-me-use-my-pendrive ?


What do I do if a usb drive decides to be read only?

In the gui I could use properties to fix this, but it needs superuser priveleges I think.

Sudo let-me-use-my-pendrive ?

Thanksfor any thoughts.
(ps its not a hardware lock)

Is it formated FAT32? You should have full access to a FAT32 USB drive, but NTFS would mount as read-only due to limitations in the kernel.

Try something like:

Code:
dmesg | tail
After plugging in the drive it should give you the device and partitions on the drive. When I plug in my USB drive I get this:

Code:
tj@T-Bird:~$ dmesg | tail
sd 2:0:0:0: [sda] Mode Sense: 00 00 00 00
sd 2:0:0:0: [sda] Assuming drive cache: write through
sd 2:0:0:0: [sda] 2015231 512-byte hardware sectors (1032 MB)
sd 2:0:0:0: [sda] Write Protect is off
sd 2:0:0:0: [sda] Mode Sense: 00 00 00 00
sd 2:0:0:0: [sda] Assuming drive cache: write through
 sda: sda1
sd 2:0:0:0: [sda] Attached SCSI removable disk
sd 2:0:0:0: Attached scsi generic sg0 type 0
usb-storage: device scan complete
So as you can see, the device is sda, and it has a single partition (sda1).

If you want to see this "live", try:
Code:
tail -f /var/log/kern.log
If /var/log/kern.log isn't the right file on your system, examine /etc/syslog.conf, possibly by:
Code:
grep kern /etc/syslog.conf
