- I have a Matsushita 5XX SCSI-1 CD-ROM drive (OEMed by Roland DG) and I
- wanted to lend it to a friend who owns a GVP A530 with a Maxtor 7312-S
- (Part code unsure, but it's a 300 MB third height SCSI hard drive made by
- Maxtor).
-
- The CD-ROM drive won't mount using ASIM CDFS or AmiCDROM. And what's
- worse, if I put a terminator on the CD-ROM, the hard drive won't boot.
- Now that's strange, since the GVP doesn't have any termintors installed
- (Yes I looked; there are pads for them but no terminators soldered in)
- and the Maxtor has its terminators installed and enabled, and the
- Maxtor's supplying terminator power.
-
- I tried using said CD-ROM on a DOS box, using an Adaptec 1520. I could
- only get the thing to work by slowing the transfer speed down to 5 MB/sec
- (SCSI-1 spec, as opposed to 10 MB/sec SCSI-2) and turning off host
- adapter synchronous negotiation (where the adapter tries to start a sync
- transfer with the SCSI devices, which is unsupported in SCSI-1).
-
- So the drive works with said switches (effectively forcing it to SCSI-1)
- and properly terminated. But it doesn't work on the GVP A530. If I try
- to install it, the HD won't boot. If I remove the terminator at the
- other end, the HD will boot, but it will spin down, spin up, etc in the
- middle of usage! Not very healthy! I don't have a way to disable
- terminator power on the GVP or the CD-ROM drive, but I could disable
- termpower on the maxtor if I had to. Are there any other ideas?
