I think you need to set bpt=8 .
It is possible to set some drives to block sizes other than 512 bytes, and
hardcoding 512 is not a good idea, especially in code that might last a
while. In a few years we might have 4096-byte blocks to let the drives use
more powerful error correcting codes.

Hi List,
I am trying to use sg_dd which goes through the scsi generic driver.

And sg5 is actually a disk.
The question that I have is, does the scsi generic driver have a knowledge
