Bruno you mentioned dd.. I am not sure what this does. > > George dd if=/dev/zero of=/dev/sda That will write zeros on each block of drive sda. CAUTION: this will destroy any existing data on the target drive specified! So be very careful when typing the command line. If you just want to fill a specific partition with zeros you can run i.e. dd if=/dev/zero of=/dev/sda1 bs=4096 where bs specifies the block size (you find that out using tune2fs).
