Hi All,

Im seeing these errors (below) between 2 and 40 times a day, 
for the last year (or more if i had the older logs) in 
/var/log/messages.
The values consistently toggle between 4 or so values, 
drifting up and down but never outside the mean +-2
/dev/hda sits around 21 to 38 degrees (according to smartctl)

Does anyone know *how* serious they are? I cant find much on 
the web other than the theory that any error is bad, so 
replace the disk.

Thanks for your time,

MrKiwi.
