Thanks for the URL.  I'd love to run a SMART analysis, but apparently  
smartctl doesn't support SATA drives.  At least the version that  
comes with CentOS doesn't (I haven't tried to rebuild it from sources  
- yet)!

I tried accessing the drive from the CentOS LiveCD, and wasn't  
successful.  There are two partitions on the drive, one for /boot,  
and the rest of the disk is managed by LVM.  I was able to mount the / 
boot partition, but I couldn't read the grub directory due to  
apparent corruption (that's a bad sign right there).  But maybe I can  
recover some of the data from the rest of the disk.  How do I mount  
the logical partitions managed by LVM from the command line?  I  
haven't had a chance to google for this/read the man page, so if  
someone has a quick synopsis handy, I would really appreciate it.
