: : I have a GRiD 1520 and two hard drives.
: : When I bought it, it had a 20 Meg JVC drive with
: : a 26 pin interface. The drive is probably bad so
: : I bought a 10 Meg JVC with the same interface. I found other
: : problems and fixed them. Now, both drives spin up
: : to speed, but I get "Hard Disk Diagnostic Failure" when
: : I boot up the 1520. I get the same error with either
: : drive.
: : I have heard on an email list (tempest-laptop@egroups.com)
: : that the drives were formatted at the factory. Does anyone
: : have a "special" format utility for the 1520 or know
: : how to format those type of drives. I tried to get technical
: : help from JVC but the technical specs page is under
: : construction. It's been 3 weeks and they haven't responded
: : to my email. Any info/help would be appreciated.
: : Thanks,
