issue running fsck DMESG clip included

[Les]

Hi.
	I am currently running FC12.  I am working on upgrading my system and
going to a 64 bit system, because I know I have some issues in this
hardware (slowdowns, internet issues etc.) they have been niggling for a
few months now, and I have been gathering cpu bucks to replace it.  So
first I wanted to run fsck to clean the disks, then do a backup, and
finally to replace the system and move to FC14 64 bit.  First step did
not work.

	I have seen messages in the boot process indicating errors in the ATA1
section, although the system appears to be working reasonably well
(given the niggling h/w errors I knew about).  This is new.   

	I wanted to run fsck, so I booted from the install disk for FC12 and
opted for the command line without mounting the disks.  when I attempted
to run fsck for /dev/sda1 I received errors that the system could not
run on an LVM volume.  How do I overcome this issue?  And if LVM's
cannot be checked with fsck, how do I ensure that I do not generate
LVM's on the new installation of FC14 (sorry, I know that is two
questions...)  I will send a separate question for the LVM/FC14 issue.
	
	Anyway, I could not capture the output message from the command prompt,
and wasn't bright enough to write it down. I will try it again if some
one needs the exact messages to help me.

regards,
Les H
