Epson Equity III + and Seagate ST- 238R Compatibility Tests.
Date: 9/7/89
Page: 1 of 1
The purpose of this test is to provide information on the compatibility of the
Seagate ST- 238R 30Mb hard drive with the Epson Equity Ill + Computer.
The test was conducted at 6Mhz using an Equity Ill + configured as follows:
Low - level formatting was initiated from MS - DOS using the Debug
command G =C800:5 after drive type "NONE" was selected in SETUP. The
format was completed in less than 5 minutes with occasional short stops at
listed bad tracks. FDISK was performed without a problem and the disk was
then partitioned into one 30Mb bootable MS - DOS partition. A high level
format was performed on the disk using Seiko- Epson MS - DOS 3.36 and
the system was transferred.
The unit was then tested for it's ability to start up from the hard drive from
a cold boot, a warm boot and when the reset switch was pushed. All tests
performed as they should. Files were loaded and removed from the disk
and various applications were run without any problems.
After the completion of the first set of tests the Equity Ill + was set to run
at 12Mhz, the drive was reformatted and all tests were performed a second
time. The only problem encountered in the testing procedure was the
inability to run system diagnostics on the drive and controller. The system
would return the message "Hard drive not installed" and return to the main
menu. When the unit was tested with IBM's Advanced Diagnostics Version
2.01, the unit would return an "Invalid drive type" message. The HDSIT utility
also failed to work correctly and locked the system up at the intro screen.
Both tests were performed at 8 and 12Mhz. This problem is attributed to a
limitation in the diagnostic programs inability to recognize a hard disk drive
in an AT- type machine when a drive type parameter of NONE is used.
