Hi Experts, we run three different external hard drives on our main system for keeping copies of important data. These drives are used regularly. They are all fairly new and so is the system. The system itself is a brand new install of Windows 7, and the diagnostics have been run on the system and it seems to be running flawlessly and with the latest drivers.
However, we occasioanlly get the following error in the system log "The driver detected a controller error on \Device\Harddisk1\DR5."
It's USUALLY when the drive is first plugged in for the day, however, not necessarily. Sometimes it occurs sporadically once or twice throughout the day. It is NOT when the drive is being used. Full backups are sent to these drives regularly and it never seems to throw these events then. Backups complete fine and verify fine.
The drives are all Seagate (purchased within a week or two of each other) and Seatools has been run on all of them, says they are all good. Also, it seems to happen with all three drives.
Anyone have any input on the error? Thanks!
