Has anybody ever wrestled with a Wang DAT SCSI drive? I just dropped one
in my FreeBSD box. I have used Exabytes before, but never a Wang DAT.
This one is on SCSI ID 6, and shows up in the boot probes as:
aic0 at 0x340-0x35f irq 11 on isa
aic0 waiting for scsi devices to settle
(aic0:6:0): "WangDAT Model 2600 01.2" type 1 removable SCSI 2
st0(aic0:6:0): Sequential-Access density code 0x93, 512-byte blocks,
write-enabled
Now.. the controller is an old Adaptec 1524, I would think it is to fault,
but it hasn't given me problems with any other SCSI devices, such as
CD-ROMS, SCSI disks and Exabyte tape drives.
I received the drive in interesting conditions. It had been in an AT&T
3B2 (yah, ancient, whee :) And I was told by a guy who knew the
administrator of the 3b2 that ''it didnt work'' and neither of them knew
why. When I looked at the drive I hope I found why: two of the scsi
terminators were missing, out of the three racks of pins. At least, I
hope this is why :)
Fixing that problem, I also pushed the scsi1/2 dip-switch to scsi2. All
of the available dip switches are as follow (also showing the state they
were in when I found the drive)
ID2 on obvious
ID1 off obvious
ID0 on obvious
PE off
OPT off
SCSI2 off SCSI1/2 switch, I switched to SCSI2
CMPR off
BS off
I tried to find help at Wang's web site, but it sucks. Can anybody help?
Or at the lease, help me decrypt what these dip-switches are for?
