Need really help - want to replace SCSI HD in MegaSTE - no clue why it doesn't work

Show all headers | View raw

Hi,

after several unsuccessful tries, I am clueless.
My Mega STE worked flawlessly with his ST157N, but it's one of the 
smallest HD you can find (no more space now for anything).
So I tried it with a IBM DORS 32160 (SCA version, but I used an adapter 
to SCSI-50pin). I didn't hear even the HD drive/motor (may be this drive 
was already dead).
Now I buyed a IBM 0662 drive (1.0 GB SCSI, 50pin).
Because this beast have the maximum of jumper for configuration you can 
imagine, I made an excerpt from the manual and upload it to my site.
You can take a look at it here: http://www.z80.eu/images/ibm0662.png
The red jumpers are my assumption what is necessary.
For the Mega STE, some told me, I should NOT use "active termination". 
For classic ST's, this would be different (e.g. for MegaFile's).
At the moment, it does not work, HDDriver (or CBHD or AHDI 6) does not 
recognize any drive except my also external connected Syquest 555 drive.

I am not aware of the sense of "Disable UNIT attention" here, also of 
the jumper "Disable T.I.Sync Negotiations".
Also, I am not sure about "SCSI bus termination power" and the 
additional "Termination Power enable" jumper (which should be related 
with the "Enable Active Termination" jumper.

Any help (Mega STE specific) ?

Regards
  Peter
