I don't think that would be an issue with SATA since there is no
shared bus.

Disk sizes are rather uniform these days. As far as I can tell
IBM/Hitachi, Samsung, Seagate and Western Digital have the same
size (200 GB = 24321 cylinders, 250 GB = 30401 cylinders, 500 GB =
60801 cylinders). The only exception is Maxtor which is always a
little bigger (250 GB = 30515 cylinders).
