SCSI hard drive. However, when I hook it up to my SCSI card (lspci says
it's an Adaptec AHA-2940U/UW/D) I get nothing, no message in
/var/log/syslog, bupkis. The module for the card (aic7xxx) is loaded,
as is sd_mod. Even if the I didn't have the module for Mac partition
support, I could still access the drive as a raw device, right?

Yes...you should be able to read /dev/sda (or whatever).

Is the SCSI chain properly terminated?

Should be. The drive case has DATerm (digital active termination). I
tried it alone and with a terminator in case DATerm died, same result.

Is termination power supplied by
some device on the chain (the SCSI card, a drive, or some other device)?

The drive is the only device on the bus (besides the card). And wait... I
have an internal tape drive. Is it hooked up? Separate bus? Hang on...

cdrecord -scanbus says (nestled amidst what looks like boilerplate)

cdrecord: No such file or directory. Cannot open '/dev/pg*'. Cannot open SCSI driver.

Hmm, indicative of a problem? But USB hard drives work fine. What is
/dev/pg* supposed to do? Can I point cdrecord at another file?
