Re: SCSI harddisk on enhanced IIe

That "do it yourself hard drive manual" was written a long time ago, before
parts were cheap.  I remember referring to that when I put my first drive
together in '90.  Frankly, you can get an old SCSI enclosure plus system
cable from ebay for pretty cheap (US$10 or less should be a fair market
rate... what's that, about MYR 40?).  I guess if you are in malaysia the
biggest thing would be international shipping if you couldn't find one
domestic or regional, because they are somewhat heavy.  The SCSI enclosures
already have the 50 pin SCSI cable in them-- then you just get a common
Macintosh style DB25M-CN50M SCSI cable and plug it into the SCSI enclosure
and you are set.  A search for "SCSI case" or "SCSI enclosure" on ebay
should reveal a ton of them (at least north america, hopefully they are
somewhat as abundant in the rest of the world).  Some even have drives still
in them.  Just make sure it says 50 pin connector.  Then it has its own
power supply and SCSI ID selector, etc. etc and you don't have to
cannibalize 3 machines to get it to work!  Look for any documentation on the
web for how to hook up an external SCSI drive to an older Mac and the
hardware should basically be the same apart from the Apple SCSI card.

The problem could very well be with the cable.  I'm sure there is a way to
go straight from DB25 to the SCSI 50 pin, but usually there are two cables,
one DB25-CN50 that connects to a SCSI case, and then the SCSI case has a
ribbon cable that goes to the drive (and a pass through to another CN50
connector so you can chain on more devices).  Or it could be SCSI ID-- make
sure the drive ID is not the same as the SCSI card.

Even if the drive is unformatted the drive LED should blink for a second
when you boot as a signal that the SCSI card is searching the chain for
devices.  Then when you load GS/OS

Advanced disk utilities is an apple application and should just be packaged
with GS/OS, if I recall correctly.  So if you put the SCSI card in the GS
you can partition/low level format/OS format the drive from there.  Make
sure to install the SCSI HD driver into GS/OS as well if it is not there
already.
