I have a 16 GB SanDisk Cruzer Blade Disk-on-key.
After a few days of use, it has become write-protected/read-only.
When I plug it in, you can see this in my Ubuntu's

You can see that is says that write-protect is on.
I've already tried:
- Looking for a read-only hardware switch
- Using Gparted to format the drive. It says that the drive is read-only so it can't write to it
- Using dd to overwrite the drive with 0s. It also can't open the device (
/dev/sdc) for writing.
- Pluging it in to a Windows 7. It too says it's read only
I did find this thread on Sandisk's forums. Does it mean that this has no solution? Must I just throw the Disk on Key after a mere days of use?
