[TriLUG] Migrating IDE to SATA boot error

[Craig Duncan]

After migrating my CentOD 4.1 server to a new SATA drive, then 
reinstalling grub, I get the following boot error

Creating root device
Mounting root filesystem
mount: error 6 mounting ext3
mount: error 2 mounting none
Switching to new root
switchroot: mount failed: 22
umount /initrd/dev failed: 2
Kernel panic - not syncing: Attempted to kill init!

The prior set of IDE drives were using LVM and / was mounted on 
/dev/md0, while the SATA drive is a single drive without LVM. Any 
pointers would be most helpful.
