- I've got a strange problem with trying to connect an external SCSI
- hard drive to a Portable.
-
- If I put an external terminator on the drive, then the Portable starts
- up with a disk containing a question mark. Putting a bootable floppy
- in will start it up.
-
- If I take the terminator off, the Portable will boot off of the internal
- drive (also SCSI).
-
- This same external drive works with or without the external terminator
- on several Mac IIsi. The SCSI cable from the drive is quite short, if
- that makes any difference.
-
- I haven't found any spare internal terminators to see if that makes any
- difference; I don't see why it would, though.
-
- What's going on?
-
- Perhaps related, this external drive sometimes isn't "recognized."
- That is, a hard drive formatting utility will claim that it has a
- capacity of 0 megs, and trying to mount it will fail. However, a reboot
- will show the correct capacity of 203, and, at that point, it's mountable.
- It's a Conner mechanism (CP3200F, I think). The software is by VCP
- Computer Products (one of the places advertising external drive enclosures
- in MacWeek).
