If you want to be able to access the drives ATA or SCSI at the drive level
there needs to be a method of doing so.

Matt asked can he go to a specified physical drive address and read a
given number of sectors from the drive. This is different than what
everyone else is giving him answers for by adjusting the FS block-size.

Can you tell me how to get/do this request? (seriously).

read(32 sectors, beginning at LBA 50)

How can one do this through the FS-layer?
