- However, I have done this lots of times. I have also checked continuity in
- the cable and connectors at various times.
-
- For the record, I may have found the source of the problem.
- Prompted by recent postings about A3000 SCSI, I did another thorough check
- from the board through the cables, terminating resistors etc. What I spotted
- was that the terminating resistor packs on the final drive were oriented
- differently. I am not sure of the internal arangement of the resistor packs,
- but it occurs to me that they have to be the correct way round?
- Perhaps someone could confirm this? Nevertheless, I reversed one of them. So
- far I have not had a read error.
- I won't be convinced that I have solved the problem until
- a) someone confirms my suspicions and
- b) I try the drives from a truly cold start (temperatures here are around
- 25-35 degC and the problem normally gets worse in winter)
- Here's hoping!!
