[comp.sys.next] HELP ... problem

Problem:
I get the Console error messages shown below when I use the HSD Scan-X scanner
and when I run Rory Bolt's SCSI hard drive formatting software. As far as I
can tell, it has never happen with any other application.

The scans come out fine on the screen, but there are many long pauses during
the scan and once in a while, the system would freeze part way through a scan.
I went through many scans (difference sizes and resolutions) and I couldn't
establish any consistent pattern or cause for the error messages.

Sometimes, when running Rory Bolt's formatting software, the error messages
would start to spew out as soon as the application has been loaded or when I
click on the HELP or SCSI-ID button (I haven't try the actual FORMAT feature
yet). There were also several times when the application runs without any
error messages. This is most puzzling!

The following is a sample of the error messages I get on the Console:
sd0: Incomplete disk transfer; bytes moved = 0x2000, resid = 0x2000, retry 1
sd0: Incomplete disk transfer; bytes moved = 0x2000, resid = 0x2000, retry 2
sd0: Incomplete disk transfer; bytes moved = 0x2000, resid = 0x2000, retry 3
sd0: Incomplete disk transfer; bytes moved = 0x2000, resid = 0x2000, retry 4
sd0: Incomplete disk transfer; bytes moved = 0x2000, resid = 0x2000, retry 5
sd0: Incomplete disk transfer; bytes moved = 0x2000, resid = 0x2000, retry 6
sd0: Incomplete disk transfer; bytes moved = 0x2000, resid = 0x2000, retry 7
sd0: Incomplete disk transfer; bytes moved = 0x2000, resid = 0x2000, retry 8
sd0: Incomplete disk transfer; bytes moved = 0x2000, resid = 0x2000, retry 9
sd0: Incomplete disk transfer - FATAL
sd0: Incomplete disk transfer; bytes moved = 0x2000, resid = 0x2000, retry 1
... etc ...

System configuration:
Cube with 68040 processor (upgraded in December, 1990)
16MB RAM
NeXT 256MB optical drive
Micropolis 1588-15 600+MB hard drive (SCSI-ID=1, terminated)
HSD Scan-X Professional scanner (SCSI-ID=5, terminated, NeXT SCSI2-SCSI1 cable)
System 2.0 operating system
NeXT Laser Printer
Dove Fax fax modem on serial port A
Cube, scanner, and fax modem are hooked up to an uninterruptible power supply

Other facts:
1) Rory's application was compiled on an '030 system (possibly running System
1.0).

Both HSD and NeXT are quite puzzled at the problem. I welcome any suggestions
or ideas you can contribute toward solving this problem.

Thanks in advance.
