Here's the scoop: I bought a Sun 4/330 with an internal 327 Meg embedded SCSI drive (a Seagate/CDC WREN IV, aka Model 94171). I then purchased a Fujitsu 2266A 1.2G drive from R-squared in an external case with power supply, etc. For various reasons, I want to put the Fuji in the 330, and have the Wren in the external case. The Fuji works fine internally or externally (BTW, $2586, including 3' SCSI cable, case, power supply, external terminator, and formatting). The Wren works fine internally; but externally, probe-scsi finds it, but SunOS can't seem to find it. It won't boot from it. It doesn't mention finding it when booting from another disk or the ethernet. Format can't find it. I called Seagate's tech support; they say that Sun modifies the drives and I'd have to talk to Sun. Sun's tech support says that yes, they _do_ modify the drives ("a firmware change"), but they won't help me unless I buy a Sun case to put it in. R-squared's tech support had me check to see that the SCSI code was in the kernel, /dev/sd* was correct, etc., but they're stuck without knowing what Sun has done to the disk. So, has anyone moved a WREN IV from within a Sun to an external case? Any help would be appreciated. E-mail or post, and I'll summarize answers to the net.

Thanks to everyone who responded: sblair@upurbmw.dell.com (Steve Blair) markm@apex.com(Mark McDonald) sukes@eng.umd.edu (Tasuki Hirata) Mark McDonald came up with: Have you tried changing the drive ID? The 4/330 wants the first external disk to be target id 0, i.e., all id select jumpers off. which fixed the problem. I don't know why the Fuji works ok as the first external drive with SCSI ID 2, but as long as it works now I'll leave it alone. Note that the 330 will find drive 0 first when probing, and will boot from it on auto-boot. If you want to change this, you need to change the eeprom Boot Device entries. I can email the details to anyone who needs them. Thanks again! --Bob I'm bob@psitech.com or uunet!psitech!bob
