kernel panic after changing fstab

I altered my fstab in an attempt to get it to recognize a multi-card reader box. I'm getting  messages:  "ext3 -fs- hda3: couldn't mount because of unsupported optional features (80008000), (80008004)", "kernel panic:not syncing:VFS:unable to mount root fs on unknown -block(0,0). Can't get cfdisk -P s (hd0,0) or hda to even see hard drive! Cfdisk yields "FATAL ERROR: Cannot open disk drive." Can someone please  give a hand?  I'm using Arch Linux v .7 and grub with the auto partition scheme prescribed by ArchLinux. Grub was working prior to the change to the fstab. Knoppix live cd doesn't see hard drive. Can't anyone here help me?:(

Re: kernel panic after changing fstab

You apparently also altered your Grub config, or it never worked. The kernel fails to mount the root filesystem, so your grub config is wrong, it didn't come far enough to read fstab. Cfdisk doesn't know about (hd0,0), only Grub does. Use something like /dev/hda for cfdisk.
