I'm about to add another 3'rd party disk drive to my PI and I've got a
few questions. I currently have an external 3'rd party tower which has
two empty drive bays and one Wren 6. I'm trying to decide between getting
~700MB or 1.2GB. One of the dealers I talked with said the PI can't
access/address past the 1GB range on a drive. Does anyone have any
information on this? Their actual experience was with a 1.6GB drive.
Can the Iris make full use of a 1.2GB drive? The specific model I'm
looking at is a Wren 7.
If I can't use the Wren 7, then I've got a choice between getting another
Wren 6 (so far it's worked fine for me) and getting a Hitachi DK515.
Has anyone had any experience using the Hitachi?

Yes, the PI doesn't have the same braindead scsi driver that all but the most recent Sun and Ultrix releases had. They were using 6 byte SCSI cmds, and that caused the block number to wrap at 1Gb. SGI has always used the 10 byte commands, and there is no problem with drives greater than 1Gb formatted. The Wren VII is a pretty good drive, and is one that we resell, so you should see no problems with it. The 515 seems to be slower, and has higher command overhead than the Wren VII. -- Dave Olson Life would be so much easier if we could just look at the source code.
