As of the wee hours of this morning, ditka is up and running with two disk drives. (Thanks Gil and Lenny!) Drive 0 is a Maxtor XT-2190, currently configured with only 8 of the 15 heads, and drive 1 is the original MiniScribe 6085. Unfortunately, the MiniScribe is showing a rather high error rate in /usr/adm/unix.log. As it ran for two years with a total of maybe two or three errors, I suspect this is due to the two disk upgrade. Before I start a rather tedious session of reconfiguring and testing, does anybody have any suggestions on where I might look for the problem based on the attached error log?

MCR2:0x2 drv:1 part:1 blk:2 rpts:1 It seems that the keys are the ST=/!Rdy/Err/ and EF=/Abrt/ parts. I suspect its telling me there was an error -- the request was aborted due to the drive not being ready. But why might that happen? My initial guess is a cable problem. One of the connectors on the 34-pin cable is a bit suspect. And both cables may be on the long side -- how sensitive are these guys to length and is that likely to cause the problems I'm seeing? Also, they are of course running right next to all sorts of power cords and other cables that one might find around the back of a machine, which probably is not an electrically benign area. How much of a problem is noise likely to be? Thanks for any help. E-mail responses are fine, or post if it seems to be of fairly general interest (like cable lengths). -- Karl Swartz |UUCP uunet!apple!zygot!ditka!kls 1-408/223-1308 |INet zygot!ditka!kls@apple.com "I never let my schooling get in |BIX kswartz the way of my education."(Twain) |Snail 1738 Deer Creek Ct., San Jose CA 95148
