Good thought.

When using "dd", out of paranoia I do a "sync" and make sure there is no 
IO activity before removing the USB device...


Plugging the device back in and:

time cmp -l mandriva-linux-free-rc2-2010-x86_64.iso /dev/sdf

cmp: EOF on mandriva-linux-free-rc2-2010-x86_64.iso

14:04.33 elapsed 0% CPU

which is to be expected being as the memory stick is larger than the iso 
file.


Curiously, that timing equates to only approximately 3.5MByte/s. I guess 
the double buffering and blocksize makes a difference on reads also.

Cheers,
Martin
