I just checked that, and even replaced the SATA cables on both drives.  
I also moved them from SATA 1 & 2 to SATA 3 & 4 on the motherboard.  
Same issues.  I know that my OS was on /dev/sda (partitions sda1 -> 
sda7).  I am booted off of the Mythbuntu 8.10 LiveCD right now, and 
wanted to do a check on the hard drives.  It keeps telling me that 
either I have to be root to do that or the device is busy.  How can I 
run fsck in this case to check the drives?

Thanks,
