No errors from smartctl on any of the drives ( 4 internal )
I believe its the write that is the problem ...
Repeated md5sum always give the same result
Repeated cmp after a bad copy always give the same results
I don't think it temperature case is not that hot, and can happen on
first test after PC has been off for a while.
