I finally got tired of running out of disk space on my Z-241 computer so I purchased a new ST-4096 to supplement my old reliable ST-4038. Problem: Both drives work fine separately, but when I hook them both up together my system has problems (ie. out to lunch). I went through numerous iterations of removing resistor packs, putting on resistor packs, new cables, etc. with no luck. During my college days I recall someone else having the same problem with their Z-241 when trying to add a second drive. I don't recall them having any success. Has anyone else run into this problem, or is just my system? Thanks, Randy Seynaeve

I don't have a 241, but I ran into a problem when adding a 4038 to my Z-100. If both drives work fine by themselves, I suspect that you have to change a jumper that tells the drive which unit it is. Probably, both are set to "0" since they each work fine alone. Set the jumper for the new drive to the "1" position. Use SETUP to tell the 241 what drive is there. My 4038 didn't come with documentation on this. As I recall, the jumpers are near the bottom on the rear of the drive. There is a set of 4 pairs of jumpers. Probably, the jumper is on an end pair (0); try moving it over to the next pair. Disclaimer: It's been three years since I did this and I don't have documentation in front of me.

Somebody tried adding an ST-4096 to one of our Z386 machines and ran into problems. After getting helpful vendor suggestions (like buy our hard disk instead, it cost 3x as much but will work nicely) we called Seagate and they said to pull some jumper on the ST-4096 (something to do with timing) and lo and behold, it worked like a charm. Unfortunately, I don't have the information available. Call Seagate. -sb -- ---------------------------------------------- MA Bell: (708) 260-5019 --------- Stefan Brandle UUCP: ...!{obdient,uunet!tellab5}!wheaton!stefan Wheaton College or stefan@wheaton.UUCP Wheaton, IL 60187 "But I never claimed to be sane!"

The documentation that came with the system said that both hard drives need their jumpers set to device select 2 (third position). The twist in the 34 wire flat cable decodes which control signal goes to which drive. The documentation also didn't mention anything about removing resistor packs. Does anybody know if this is necessary? The doc says something about removing the pack when adding a second floppy, but nothing about what to do on a second hard drive.

YES!! the only hard drive that wants to have a resistor pack is the drive on the end of the data cable... * Matt Parker / Laz Long * Be wary of strong drink, it can make you * * 11 Lawrence Ave * shoot at tax collectors...
