I am having some troubles with my Wren and my WD7000 controller. At intermitent times (can be at bootup, or while running an application.), the Wren's drive light will come on very brightly, and stay on, and the machine freezes up. Only during disk accesses does this problem occur, and I noticed it also increases in periodicity when I increase the length of the SCSI cable, or (I don't know why), add more memory to my machine (from 4 to 8 megs). I talked with a WD techie, and he suggested it might be a Termination Power problem, and that I should switch the drive to use the cable's power rather than the power provided to the drive directly. When I change the TP jumper to that position, the drive refuses to spin up, and I have event tried the TP jumper on the WD7000 end (near the 50 pin plug) to no avail. Has anyone out there done this? Has anyone ever seen this happen before and know how to solve it? Right now it is nothing more than an annoyance, but now that I am switching to Unix, I cannot have my machine crashing periodically at all in fear of data loss and problems with Unix.
