Correction to the error message, it is this:
The driver descriptor says the physical block size is 2048 bytes, but
Linux says it is 512 bytes.
or at least that is what I get without using the bs=4M option
I am wondering whether it is a fault of the iso image (recent download
of the Rescatux 4.0beta) which I am trying to use without luck on an old
32bit Celeron?? .. with Win XP to repair its admin pass and booting
which seems to take for ever.
I am trying to use the empty part of the stick to copy and store
temporatily some important files before I mess with it or install debian
