Amiga 3000 Hard Drive issue... quantum xp32150

[Amiga4k]

The above A2000 worked with the 40 meg drive.

Suggest you disconnect the hard drive, and wait it out. If the   request for the Workbench appears, all is OK. Does your SCSI cable have an "orientation notch". It is possible with un-notched cables to insert the cable FLIPPED.
Glad your still at it, I'll be moved down to FL late Jan06.
As soon as I unpack the Amiga parts, and test gear, I can be somewhat local to you.

As for low-level formats and SCSI vs IDE. As an Amiga owner, re-seller, and trouble-shooter, it has been my experience that SCSI drives should be low-leveled, data-blocks verified, and  then partitioned. After "in-service", low-level formats are only used when a drive becomes hopelessly corrupt and fragmented beyond normal data-block intregrity repairs. (AmiBack or QuarterBack Tools).
I would never low-level an IDE drive.

Melott,

Thanks for the comment.

cbcvenice,
As I said, your system worked PRIOR to your changes. Do the test I asked, and report back. As for the SCSI-08 chip, it is NOT needed for internal SCSI connected drives. Your reading too much into my email and comments.
Re-stated to all: The A3000 internal SCSI port and SCSI controller chip are adequate for the internal hard drive. Adding a drive on the external SCSI port "overburdens" the -04 and Proto SCSI controller chip revisions.  The -08 chip was created to address these timing issues on the SCSI buss.

Trying to DIY sometimes leads to disaster. My offer still stands, but the cost went up because now you'll have to ship  the drive 2 ways.

cbcvenice,
Please understand this is not a rant, or anything similiar.

1)Computer works fine when just the original HD. Like I said.

(2)You purchased a PC scsi card and "dual HD scsi cable" ($7.00) and am trying to set up a 2.1gb Quantum Atlas xp32150 as second HD with said cable.  NO-NO-NO !!!!
You should have asked --- you need another Amiga SCSI card, not an Windows PC SCSI card... You could have gotten the right card, and cable (from me) for less than $35.00.
 
(3)You put terminator jumper on it and change the id to "2" with another jumper, but Amiga 3000 will not get past a "white or grey" screen with this arrangement.  ---- Just what did you actually attach to the drive. The drive is more than likely the original Quantum LPS 40 meg, and I have the proper "Terminator resistor" sipps in my parts bin.  What is strange is the fact you said it worked without them.

The thing I am not sure about is what to do about termination on original 40mg quantum prodrive...some documentation says it has no terminator, but a resistor...  I have the correct sipps in stock.

Any more help on this would be appreciated. Lastly, is it really worth going to Amiga OS 3.1, 3.5, 3.9 for this A3000/16 with 2meg chip and 4meg fast ram?

A 16MHz can not handle 3.5 and above. It is too slow.
You can not install an 040 or 060 card w/o a $110-$130 chip upgrade first. (Buster Ramsey, DMAC).
[I am prepping an A3000 030 with these chips Nov 18th].After that date, I close my Amiga part bins, and packup for the move.

If anyone is willing to Agree or Disagree with what I said, I ask you to please reply. This guy really needs the truth.
(Yes I gave him a price to prep, partition, install AmiagDOS on the drive, and offered free phone help during all problems).

Melott,
Here is an edit from the National Amiga Technical journals:
The RAMSEY and DMAC chips are important A3000 custom chips that, among other things, implement part of the A3000's onboard DMA SCSI host adapter. Nearly all A3000 were delivered with the revision combination of DMAC-02 and RAMSEY-04. The problem with this combination is, the DMAC-02 does not like 68040 boards like the A3640. There are both heat and timing problems. If you are lucky, the tolerances of your DMAC-02 are wide enough to work together with the A3640. If you are not so lucky, SCSI will not work correctly anymore with the A3640 installed.

Your very fortunate your DMAC is either an excellent 02, or you have an 04 in your machine. It's extremely hard to be critical of you, as your knowledge base equals or exceeds most Amiga users I can come in contact with. If you would like a copy of my Amiga technical journals and file database on CD, please let me know. It's over 650 Megabytes on a PC CD, so you'll need to turn off CrossDOS via a shell or command to see the long file names.
