- We recently had problems with a MacIIcx not recognizing
- a new Quantum 240 hard disk attached to it. The company
- we bought the drive from claims that they connected it to
- an IBM and it works fine. They think that our setup was
- incorrect. We set the SCSI ID to 2, and they are telling
- us that it should have been set to 1.
-
- 1) Do the IDs have to be sequential? i.e. The internal HD
- is device 0. Does the next hard drive attached have to have
- ID=1, or can I assign an arbitrary number between 0 and 7?
-
- 2) A friend of mine told me that device IDs 0, 1, and 2 are
- reserved for hard disks and that numbers above 2 are reserved
- for removeable media and other devices. Is this correct?
-
- Thanks,
