Hard Disk 20: Failure To Launch Application Or Format



PROBLEM DESCRIPTION: Hard Disk 20 will not initialize media, or
applications fail when launched. Also, sometimes application files will
not transfer successfully to the Hard Disk 20.

BEFORE YOU START: Familiarize yourself with the Hard Disk 20 Owner's
Manual and Hard Disk 20 Technical Procedures.

CAUSE: Hard Disk 20 controller board might contain a HAL instead of a
PAL chip.

CURE: Check the serial number of the Hard Disk 20. If the serial number
is F619xxx or higher, and the controller board contains a HAL chip at
board location C3 (PAL is 16R6 is silk screened next to the chip),
remove and replace the Controller Board using a service spare. Reconnect
and power-up the Hard Disk 20. Try to initialize the drive. If
initialization fails, refer to the Hard Disk 20 Technical Procedures
for more troubleshooting information.
