I'm not sure of that.

Have a look at the "/boot/grub/device.map" file. Mine has:

(hd1)   /dev/hdb
(fd0)   /dev/fd0
(hd3)   /dev/hdd
(hd0)   /dev/hda

Copy? I don't understand.

But:

  nimrodel:/boot # l initrd*
  lrwxrwxrwx 1 root root      29 Sep 28 02:06 initrd -> initrd-2.6.16.21-0.25-default
  -rw-r--r-- 1 root root 2440205 Oct  5 21:42 initrd-2.6.16.21-0.25-cer
  -rw-r--r-- 1 root root 2438012 Sep 28 02:06 initrd-2.6.16.21-0.25-default
  lrwxrwxrwx 1 root root      25 Oct  5 21:50 initrd-cer -> initrd-2.6.16.21-0.25-cer

initrd is a symlink, and you should check it is pointing correctly. Also:

  nimrodel:/boot # file initrd-2.6.16.21-0.25-default
  initrd-2.6.16.21-0.25-default: gzip compressed data, from Unix, max compression

it is a gziped file, so probably it can be checked. Or even easier, 
rebuilt wit the command "mkinitrd". Do it, it won't hurt.
