Need SCSI help building ghetto Stone array
Though some helpful bits + pieces could be gathered from these posts, none provides a good starting point, so in the spirit of aggregation i'd be grateful if anyone who has some kind of external storage attached to his/her O2 posts the make/model/specs here, so i can update the The O2 Hardware Aggregator
What should I keep in mind while looking for an external SCSI case + HDs?

I have heard that the Adaptec chip and IBM DDYS drives might have troubles in some cases.
I know I should not say that be if you have a PC with an Adaptec 2940 you can test the same config and might not work as well...
Check if drives have a "Force SE mode" jumper....
