ST-4096
The ST-4096 is a high capacity 5.25", full-height 80MB hard
disk drive. The drive parameters (1024 cylinders, 9 heads)
are not included in the Epson ROM BIOS version 2.20, or
earlier, drive type table. Under MS-DOS, you can use the same
procedure as for the ST-251 and obtain approximately 69MB
of usable storage (the 9th head is ignored).
A common application for this drive is in a file server for a
Novell network. This presents a problem as the NetWare
operating system works exclusively from the computer's ROM
BIOS drive type table, and does not honor the alternate
hard disk parameter table that programs such as SpeedStor
create.
Here is a solution for this situation that will yield
slightly over 70MB:
1 -
Prior to physically installing the drive, turn it
over and locate pin 2 of the 34 pin edge connector.
This will be the first pin from the left on the
component side of the drive's printed circuit board,
when viewed from the rear of the drive.
2 -
Mask off pin 2 with a small piece of thin tape -
regular adhesive tape works quite well. Do not overlap
onto pin 4.
3 - Install the drive and run the Epson SETUP utility.
Under MASS STORAGE, go to Drive C and select type 43
(1024 cylinders, 8 heads).
4 -
Perform the low-level physical format (HDFMTALL),
remembering to enter any listed bad track locations.
You are now ready to go on to the Novell installation
procedure. Refer to the NetWare Installation Guide for details.
(Note: the above procedure is also useful under MS-DOS 3.30.
After HDFMTALL, simply run FDISK to set up the partitions
and logical drives and then FORMAT each logical partition.)
Pin 2 is the HS3 (Head Select 3) signal, which is used to
select the 9th head. Masking this signal off will permanently
de-select the 9th head, preventing the system from generating
an error condition.
Although this procedure does not yield the full 80MB capacity
of the disk drive and is not recommended as a standard
practice, it may prove useful in certain situations.
