IIRC, something on the order of 18 feet (5 meters?) is the maximum SCSI chain length according to the ACTUAL SCSI spec, heaven knows how Apple might have borked that along with the shredding the ACTUAL SCSI connector spec.
Some basic SCSI Voodoo troubleshooting steps:
Determine if the termination on the external case itself set to ON or OFF? :?:
Sometimes there's a clear window on the bottom of the case that shows if the termination resistor SIPs are installed or not.
Did you remove/disable the ex-internal, now external, drive's SCSI ID Jumper? :?:
IIRC, internal drives are set normally to SCSI ID 0, the Mac Controller being SCSI ID 7 on the 8 ID SCSI spec. or the reverse If I don't RC.
Having the external set to 0 with the enclosure set to 1-6 would very likely cause all kinds of SCSI Voodoo!
With which of your Macs are you testing your cobbled together External Drive? :?:
As an aside:
IIRC, internal SCSI Optical Drives are set up at SCSI ID 3 by Apple, so, gots CD in the box? :?:
That's all that comes to mind ATM, post some more info and maybe something else will shake loose after I've had the rest of my coffee and jangle the 'ole gray matter's convolutions with a bit more data input! [] ]'>
