Mac SE internal hard drive issue

Hi All, I purchased an Apple labeled IBM SCSI 350mg hard drive for Macintosh SE.
Model DSAS-3360 P/N 84G8452. I get this error message in Lido, "Initialization failed, check
termination or Jumper settings", something like that. Now the drive has 7 jumpers on it. So
can anyone tell me, 1. Does it need termination? 2, Does anyone know how the jumpers need
to be set, Left to Right, and how many need to be covered?
Thanks so much for all the support.

Yes, termination at both ends of the SCSI chain is a must.
Here is a data sheet collection that should cover all settings:

In short, you want to close jumper 6 to enable termination.

Hi 24, Thanks for this good information, after fiddling around a bit I managed to identify Jumper 6 (Ha!)
and have set the drive to ID=0 and I am now getting a phase error at that jumper, 0 (whatever that means).
So should the internal hard drive be set to ID=0 or a different one. I previously got a phase error at jumper 2 when I had it covered but uncovered jumper 3 and at jumper 6 when I left it uncovered. Phew!
Thanks to all,
Brad Hansen

Sorry to hear that Brad. No idea what a phase error may be.
Can you try interleave 2:1 or 3:1 with the IBM HDD?
The Termination jumper must be closed, but SCSI ID should not matter.
Apple used ID=0 for the internal drive, thats right.

Hi there,

May be the drive should be initialized with another utility. Or initialized on another machine... I've found this interesting thread from a site...

Yep, I recall similar threads.
The bottom line usually is: Get a SCSI to CF adapter and say farewell to spinning things. Wink

For the SE you want a SCSI to SD adapter (SCSI2SD).

Need to use OSX to initialize and set up the SD card.
2GB micro SD is all you need.

Hi All, Okay I covered all jumpers except 1,2,3 and Lido found the drive and identified it as "Not a Macintosh drive. However I was able to initialize and partition the drive and install system 6.08 on
it. But the first Volume only allowed me partition 1.3 msg, the second 33 mgs is that standard?
Thanks!
