When you attempt to use Automated System Recovery (ASR) to
restore to a replacement system or disk, you may receive the following error
message, even if the new system disk appears to be the same size as the
original system disk:
Setup was unable to restore the
configuration of your system
because of the following error:
The
capacity of the current system disk drive is
insufficient, and cannot be
used to recover the
partitions on the original system disk.
The
replacement hard disk drives must be at least as large
as the disks
present on the original system.

This behavior can occur if the replacement disk is slightly
smaller than the original system disk, even though they are shown as having the
same amount of space. This can occur because two disks that appear to be of the
same size may not have the same number of sectors, due to differences in disk
geometry and rounding errors in the display of disk space.

To resolve this behavior, use a replacement disk that has
identical disk geometry to the original disk, or use a larger disk.

Slight differences in the number of available sectors on a
disk may also occur between disks that are the same make and model, but which
have different firmware revisions.
