Okay I am now 3 for 3 on hard drive not working in my 700. Starting to lose my mind.

First drive is a Hitatchi U320 146GB SCA-2 80pin drive with adapter system completely fails to notice it tried different cables passive passthrough terminators active termination using my external enclosure completely invisible to the mac.

Drive 2 Seagate ST34501W 68Pin drive attached using a 50 to 68 pin adapter on the logicboard drive is recongized but reports capacity as 0MB, 0 blocks HDT and Linux report  Medium Error Medium format corrupt.

Drive 3 IBM DDRS-34560 68pin drive also recongized by system reports proper capacity 4.5GB but again HDT and Linux report Medium Error Medium format corrupt.

The drive I got with the system a 540MB Quantium Drive works perfectly.

My scsi chain is as follows Internal IBM Drive ID 0 with active terminator on cable, External Zip100 drive ID 6, Apple e600 CDROM ID5, Quantium 540MB in a APS Drive enclosure ID 1 and active termination provided by enclosure. I believe everything is terminated correctly.

I am completely stumped, I think I may just save for one of the SCSI2SD adapters hopefully that will just work
