I am trying to add a maxtor 4380 (e?) to my 3/50. I have an emulex controller and a micropolis 1335 that are working on it properly. When I try to do surface analysis or format the new drive (using stand/diag) I get lots of "sense errors" and "illegal parameter" errors. The jumpering is right, I have checked the cables and addresses. What else should I do?

I had the exact same problem. The parameters in /etc/format.dat are wrong.
Replace the Maxtor entry with:
disk_type = "Maxtor XT-4380E" \
: ctrl = MD21 \
: ncyl = 1218 : acyl = 2 : pcyl = 1224 : nhead = 15 : nsect = 32 :
: rpm = 3600 : bpt = 20940
partition = "Maxtor XT-4380E" \
: disk = "Maxtor XT-4380E" : ctrl = MD21 \
: a = 0, 14880 : b = 31, 29760 : c = 0, 584640 : g = 93, 540000
and this should work fine. You might want to extract the defect list first
and save it to a file. After you update the /etc/format.dat file, then
read in the defect list from the file (after you change the parameters,
the manufacturer's defect list is no longer readable.)

The machine came from Artecon years ago with 3.2 on it, I had to put 4.0 onto it. I managed to do it without touching the label, thank the deity. All I could figure out about the label on it was cyl 1218 alt 2 hd 7 sec 33 and it seems to have an Adaptec ACB4000 on it. I went into format (off the tape) to get the defect list, and format said it had 1220 physical cylinders -- 1218 + the 2 alt? The beast has about 32 errors in its list. Now I check the other Artecon disk we have, and it's a Wren III, but with different params than format.dat: sd0: <CDC WREN III cyl 963 alt 2 hd 9 sec 33> format.dat says: #disk_type = "CDC Wren III 94161-155" \ # : ctlr = MD21 : fmt_time = 4 \ # : ncyl = 965 : acyl = 2 : pcyl = 967 : nhead = 9 : nsect = 35 \ # : rpm = 3597 : bpt = 20880 Sigh. -- Anthony A.
