'/usr/sbin/grub-probe: error: no such disk.

Debian Squeeze , Kernel update gave errors for building new grub config after drives replaced and restored from backups.

Symptom:
# cat /boot/grub/device.map
shows old drives, not new drives

Fix:
# grub-install --recheck /dev/sda
Installation finished. No error reported.
# grub-install --recheck /dev/sdb
Installation finished. No error reported.
# cat /boot/grub/device.map
now shows correct drives and update process completes successfully
