I have a thumb drive with a strange problem. I can't move files off if it, because it apparently has a "read only file system". I can't modify permissions on the memory stick with sudo chmod, it always responds that it has a "read-only file system". How can I change this?

Perhaps you already checked this, but did you accidentally set the write protect switch on the thumb drive?

I never knew there was such a thing. How do you set the write protect switch on a thumb drive? And how do you unset it?

Is it a non-native file system, eg ntfs or fat

How would I know? I bought a thumb drive and plugged it into my computer. Can you explain to me how to find out?

Not all thumb drives have the switch, but those that do usually implement it as a tiny rectangle of plastic near one corner of the drive. It may not be obvious, and you may need a tiny screwdriver or something similar to move it. Think of a little bitty slide switch.

Regarding the file system types, you can use gparted to report on the file system structure on the drive. Just fire up gparted and select the thumb drive, then look at the table of partitions. If you don't have gparted then you can get it using synaptic or apt-get.

What's the brand and model of your thumb drive? We can look up the specs to see if that can be of any help.
