Looking for Quantum Scsi hard drive specifications

Posted on 2006-05-23

I need to find a Quantum Atlas IV 9.1Gb Scsi hard drive to clone an existing drive. The part number indicated on our existing drive is KN09J011. When searching in eBay or Google for a Atlas IV 9.1Gb, I find many many different part numbers ex: (mostly) KN09L011, (some) KN09J011, a few KN09J011-W. I've spent many hours searching but I can not find the exact specifications for each of these p/n. Are these all the same with minor manufacturing/assembling details or are they different (geometry, heads, etc) drives ?

    Assisted Solution

    I would think that all the Quantum Atlas iV 9.1GB SCSI drives are functionally the same.  The difference in part numbers is likely due to the PCB revision on the drive.  Here's some info on the drive:

    Quantum is gone, bought out by Maxtor, which was recently swallowed whole by Seagate...

    Anyway, Quantum Atlas IV specs are still online at:

    I had found the Quantum online specs mentionned before, but it gives only general description and specifications. I'm trying to find the exact differences between p/n KN09J011, KN09J011-W, KN09J011-B, KN09L011, KN09L462, etc.

    Thanks for the help.

    I finally found the answer after calling Maxtor. If this can be of any help to someone else later on:

    KN09L011: 9.1 Gb Scsi Quantum with a 68 pin connector

    KN09J011: 9.1 Gb Scsi Quantum with a 80 pin SCA connector.

    Besides the connector, the drive is identical.
