Question : Problem: Looking for Quantum Scsi hard drive specifications

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 ?

Thanks.

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

Anyway, Quantum Atlas IV specs are still online at:
