A1200 + 1230scsi.device + HP CD-Writer 6020

MakeCD version:

MakeCD 2.3

Computer:

Amiga 1200T, OS 3.1, Blizzard 1260 (68060), 2+48 MB RAM

SCSI device:

1230scsi.device 8.5 (also tested with 7.19 and 8.3)

CD writer:

HP CD-Writer 6020 1.07 (10/21/96)

CD-ROM drive:

TEAC CD-ROM CD-516S 1.0D
SONY CD-ROM CDU-55S 1.0t

Other devices at the same SCSI bus:

QUANTUM FIREBALL1280S 630C
ZIP 100 E.11

System works fine. No SCSI hangups with reselection turned off for writer and CD-ROM. 14 CD-Rs written, all successful.

With this setup it is possible to get SCSI hangups when reading from a CD-ROM and writing the ISO image to a file on a SCSI hard drive. This is a common problem with earlier versions of the 1230scsi.device, using version 8.1 or higher fixes this problem (SoftSCSI on Aminet can be used to patch older ROMs.)

Tests performed:

Tests performed:
• Write an audio track direct from CD to CD-R at 1x speed. This worked perfectly.
• Write an audio track direct from CD to CD-R at 2x speed. This failed with a buffer underrun using a 2x CD-ROM but works with a faster CD-ROM.
• Write an audio track from CD to CD-R at 2x speed using an image file. This works perfectly, even if the image file is on a hard drive on the same SCSI controller as the CD writer.
• Write a data track direct from CD to CD-R at 2x speed. Worked perfectly.
• Write a data track from CD to CD-R at 2x speed using an image file. Worked perfectly.
• Write a data track at 2x speed from a filesystem directly to CD-R. Works perfectly.
• Write a data track at 2x speed from a filesystem using an image file. Works perfectly, even if the image is on a hard drive on the same SCSI controller as the CD writer.

The buffer size used for all these tests was 8 MB, the Parallel read/write and use ExAll settings were both turned on and all hard drive partitions have 1024 buffers.
