USB flash drive changes to read-only on the fly

[Daniel Louw]

This might be a silly question, but it is very frustrating.

I have this memory stick, a 2 GB one formatted with FAT32. 

I was working on a .C file stored on the memory stick, saving as I made
progress with the code. Then all of a sudden I cannot save anymore. I
get an error saying the disk is read only. I cannot create new folders
or files or anything. chmod doesn't work, it simply says read only
partition. What the hell?

Could it be because I compile directly on the disk? I use the disk a lot
at university and it is much easier to just work directly on the disk.

Any help will be greatly appreciated!

Regards
Daniel
