[mythtv-users] Is this a failing drive?

[Don Brett]

This is a little off-topic, but it's a new drive on a new Mythbuntu 
installation.  Symptoms are:

-partition table got corrupted (after about 50 hours on the drive); an 
8-hour low level format got it back
-the box occasionally freezes-up for a few seconds
-I see multiple instances of these errors in /var/log/syslog:

 From /var/log/mcelog, I see multiple entries of this:

I replaced the sata drive cables, disconnected the dvd drive, tried a 
different power supply.  I also tried another drive on the same box (but 
it was an ide) and had no errors.  With a different motherboard...still 
got the "re-mount" errors but none of the "[Hardware Error]" entries.  
Anyone have a suggestion?
