Has anyone experienced having a location that has dirty power problems and what solution have you come up with? I have a store that in the last 4 months has gone through 50 hard drives. It was on APC ups's, since this started they have had a new grounded dedicated circuit installed and are on a Trip-Litte line conditioning ups but are still going down . The computer system is an old P2 running SCO UNIX with SCSI drives.
