Since this is a test, you're going to have to learn something for yourself.   Go to T10.org & T13.org, which has the various command-sets that govern ATA (which covers IDE, SATA, and ATA disks), as well as the T10.org which has SCSI command specifications.  The SCSI spec handles parallel and serial SCSI which handles SAS, fibre channel, USB, and older SSA devices.

You need to look up the READ command, and see what parameters you pass it to get to block #10. There is more than one type of READ for various types of disks, and some have different parameters than others. You will learn a lot.

no calculations are necessary.  Disk drives are random access, not sequential access.   They support the concept of going directly where you want w/o reading anything.  You simply reposition the read head with a SEEK command.

and when you seek you tell it the block # you want it to go to.
