[CentOS] LVM repairing or back to regular ext3?

Can anyone point me in the right direction for correcting errors on an HD when using LVM? I've tried e2fsck and indicates bad block. I've tried with -b 8193, 16384, and 32768 and no good.

I've found some info about reiserfsck on google, but this utility doesn't seem to be included in Centos4.3. I did find it on my old FC1 box.

I am thinking now I really should have went with just regular 83 Linux ext3 partitions. Arrgghhh.

And if I want to switch to 83 Linux instead of 8e LVM, whats the best way, or at least a feasible way? I can pop another drive in if I need to move data around, but I don't see how, as I can't mount the LVM partition (hda2).
