Yes, at the moment 3 of the 4 sda partitions are failed.  By hardware,  
do you mean the disk or the controller?  Any idea why this would start  
occurring after a power loss?

It's not much money to replace the controller.  The disk also wouldn't  
be too bad, and probably is in warranty.  But I'd like to actually  
verify it's bad before going down that road.

If there are no other good PCI SATA cards out there, I'd need a new  
motherboard or new machine, since PCI is all I have in this computer.   
(It's rather old...  perfect for the job I've given it.)

Can anyone read anything more from the syslog entries and other info I  
posted in my original message?
