Perhaps you should obtain the ANSI standard document that describes the ATA 
standard. It's number is X3T10. It can be downloaded from the internet at:
ftp.dt.wdc.com/pub/standards/ata/ata3
This standard tells you _everything_ about ATA devices, from hardware, 
registers, commands, LBA, ATAPI, programming, DeviceID etc etc.
If you don't have 'net access, I can't suggest any other sources, sorry.
