works for me :-)
Are you sure you are getting all 520 bytes from each sector and not
only first 512 bytes? Can you verify it?

Hi David,
it seems you're right.

# dmesg | grep sd2

sd2: 4173MB, 520 bytes/sec, 8414494 sec total
so, i dumped 4308220800 bytes from each drive and:
4308220800/520 = 8285040
4308220800/512 = 8414493.75
Yes, it seems, I got only 512 bytes from each sector.
