 There will be diagrams on the HDs, which is good, because the patterns run from left to right OR right to left (just like with IDE HDs).
-=== SCSI HD ID Jumpers ===
+=== Setting ID Jumpers on 68-pin drives ===
 There will be 4 jumpers, labeled "0 1 2 3" or "1 2 3 4" or "1 2 4 8".  Jumpering a combination of these will give IDs of 0 thru 15.  Think of the "1 2 4 8" pattern: no jumpers gives 0, all 4 jumpered gives 15 (1 + 2 + 4 + 8), jumpers on 1 & 2 gives 3, jumpers on 1 & 4 gives 5, jumpers on only 1 of the 4 gives 1 or 2 or 4 or 8.

 NOTE: Our current test script has trouble displaying the in-progress detail for more than 5 or 6 HDs, so, even tho' we could test up to 16 HDs on this test station, doing only 5 or 6 is easier to manage.  Also, testing more than 5 or 6 72GB HDs can take 20+ hours to finish, so schedule accordingly.

 === Other Jumpers ===
 -pin SCSI HDs often have a 2nd set of jumpers.  These are not for ID numbers, but rather for settings like termination, spin delay, & other SCSI-specific & esoteric things we usually do not care about.  REMOVE all jumpers from this pin array.  Then, read the pin diagram, looking for "Motor Enable", or a similar phrase.  Usually the HD will "spin up" & be recognized without this jumper, but if not, try adding a jumper here.
