Everyone,
I installed a sata drive on a SuperMicro with SCSI drives. No problem with the installation. Everything went as expected as the os recognized the drive and assigned /dev/sdc to the new 300 gig Seagate drive. I had planned to use this drive for backup tarballs.
The drive had been functional for about a week with no problems. Apparently it went out today when I tried to reboot the system. Now the boot process brings the system up into repair mode, but mounts the / partition in "read only" status. I can see that the original /dev/sdc is present but /dev/sdc1 is not present.
I removed the drive completely and predictably /dev/sdc is no longer present.
The problem I have now is that I have an entry in /etc/fstab that references the disabled drive that I am unable to change because I can only get to /etc/fstab in "read only" status. I am sure there is way to remove the entry to /dev/sdc1 but I have not been able to do so.
Any help would be appreciated

You should be able to boot off the CentOS 5 (assuming its 5) DVD or CD1 and go into "linux rescue" mode which will allow you to mount the / drive in rw mode thus allowing you to remove the entry from the /etc/fstab. Look into that option, I have done it before, but can't remember the exact steps.
A quick Google search found this:

When your / is mounted ro, you can remount / in rw using this command
# mount -o remount,rw /
Then update your fstab and reboot
