It's a brand new disk (well, less than three months old), and it  
pretty much did it from the get-go (as did the previous disk).  I've  
replaced the SATA cable and updated the system BIOS (it's a Lenovo  
ThinkCentre M51, and I am using the on-board SATA controller) as  
previously suggested.  I was hoping that the errors logged with  
syslog would help uncover the root cause.  It just so happens that  
the first time after I configure syslog to log to another system, the  
disk becomes unbootable.

I already replaced the cable, and this is is an intermittent error.

Great idea, booting from the CD as I type this.  I had tried booting  
the install CD in rescue mode, but that resulted in a kernel panic  
when it tried to mount the disk.  Let's hope I have more luck with  
the LiveCD.
