Bad Swap Partition

I am using RedHat 8.0

During startup I get some segmentation faults. I booted with the rescue disk and ran fsck on /dev/hdb1 and /dev/hdb2 and there were no problems. When I did a fsck on /dev/hdb3 which is my swap disk i get the error:

Couldn't find ext2 superblock, trying backup blocks......

The superblock could not be read or does not describe a correct ext2 filesystem. If the device is valid and it really contains an ext2 filesystem, then the superblock is corrupt, and you might try running e2fsck with an alternate superblock

e2fsck -b 8193.

I tried superblock 8193 and I get the same error message. I have seen this problem in some previous posts but it looked like the only way people have fixed it was to reinstall the entire operating system. So my questions are...

1. Can I remove the swap partition? And should this fix the problem?

2. Is there anyway to make sure the file system is ext2? (i did not install this system)

3. What would be a good live cd to use if I had to backup my hard drive and reinstall everything?

Ad 1&2) Unlikely ... unless the system has so little RAM that
it actually NEEDS to swap during boot this isn't going to
fix the problem ... in terms of the fsck: swap isn't ext, so
it will never work. You can try to boot to init 1, turn off
the swaper, and re-format (mkswap) the swapper ... my
suspicion however would be faulty RAM, or clock/timer
problems with the motherboard and the RAM.

Ad 3) Any, really... knoppix, RIP, System Rescue CD,
any/all will do.
