I have purchased a Praim 738 Disk drive (330MB) to use on a Future Domain TMC-885 SCSI controller. There was no documentation with the drive. Can anyone please tell me what the jumper seting on the drive are. The bottom of the drive has three jumpers. W6 was jumpper when received w5 not connected W4 No jumper pins (not connected) W3 Near terminator resistor pack (not installed) resistor pack also not installed. W1 no jumper pins (not installed) 10 jumper pairs next to SCSI connector. scsi connector . . . . . . . . . . . . . . . . . . . . ^ |---| | SCSI adr. ---Motor control ? The motor control jumper seem to be the correct definition for the fourth set of pins, since if jumper the motor spins up on power up. Can anyone provide further details on the pins or better yet know the correct jumper setting for this controller. Thank you for you help. _________________________________________________ | ____ ___ ____| | | / \ __ \ / | David L.

Be advised, however that my experience with these drives has been horribly negative. There is some very obscure bug which prevents some UNIX systems from properly formatting the last slice, or partition if you will. I don't know if it's true for ALL unix's but it's true for Motorola's SYS V rev 3 and it's true for Tektronix's UTek 2.3 BSD 4.2+. So that's 2 for 2 of the ones I've tested it on. I have worked around that by partitioning the drive with a small final partition, and making it a swap partition. Don't try to build a file system in it!!! Now for your jumper settings. > The bottom of the drive has three jumpers. > W6 was jumpper when received Open = Soft SCSI bus reset [factory default] Closed = Hard SCSI bus reset > w5 not connected Auto sequence up delay [factory default - installed] > W4 No jumper pins (not connected) Factory diagnostic ??? > W3 Near terminator resistor pack (not installed) Terminator power from drive [factory default - installed] > resistor pack also not installed. > W1 no jumper pins (not installed) Factory diagnostic ??? > > 10 jumper pairs next to SCSI connector. > > > scsi connector . . . . . . . . . . > . . . . . . . . . . > > ^ |---| > | SCSI adr. > ---Motor control ? > > The motor control jumper seem to be the correct definition for the fourth > set of pins, since if jumper the motor spins up on power up.
