I was comparing the 60GB disk specifications and 30 GB one. There is
one difference with respect to "Data Storage Physical" key feature. It
shows for
60GB -- Number of disks= 2 and Data heads =4  and for
30GB -- Number of disks= 1 and Data heads =2  .

Does the number of disks or data heads have any significance on
upgrading the disk from 30GB to 60GB?
