Appendix B — Troubleshooting
• USB needs a Power Macintosh with Mac OS 8.5 or later; it simply
will not work with earlier hardware, such as a 68K Macintosh, or
earlier operating systems, such as System 7: use SCSI with these.
The computer hangs up while recording, or there is data loss
A poor connection between PowerLab and computer, or bad cable.
• Ensure that the cable is firmly attached at both ends and try
again. If there is still a problem, try a new cable.
SCSI problems: two SCSI devices on the bus have the same SCSI ID,
or termination is incorrect or unsuitable.
• Check that each device has a unique ID number and that the SCSI
chain is terminated correctly. (As a last resort, if the PowerLab is
the only connected SCSI device, try leaving it unterminated.)
The PowerLab doesn't work or the program crashes after a short time
A poor connection between PowerLab and computer, or bad cable.
• Ensure that the cable is firmly attached at both ends and try
again. If there is still a problem, try a new cable.
SCSI problems: two SCSI devices on the bus have the same SCSI ID,
or termination is incorrect or unsuitable.
• Check that each device has a unique ID number and that the SCSI
chain is terminated correctly. (As a last resort, if the PowerLab is
the only connected SCSI device, try leaving it unterminated.)
The SCSI adapter card is incompatible with the computer or the
PowerLab or both. We cannot guarantee that the PowerLab will work
reliably with a card we did not supply.
• Try another card, preferably one we supplied.
Partitioning problems on the hard disk (while rare, this can happen
even with new disks).
• Use disk-checking utility applications to check the SCSI driver
and root directory on the hard disk. Partitioning programs may
