First, be sure you have read this about termination power <http://www.lowendmac.com/tech/termination.shtml> and see if your 3rd party drive is supplying it. It's important for powerbooks with IDE internal drives. That said: I have several external Apple and 3rd party CD-ROM drives, that work just fine with my desktops (4400, 6500, 7100) with the termination switch built into the external case. Some are older drives, (1400 era), some new. No matter what, I can't get those drives to work with my 1400 or 5300 unless I have the drive on AND a CD in the drive as I power up the machine (warm boot might work too, I forget). Regardless of how I terminate them. If there isn't a CD in the drive when the drive first gets polled, those powerbook models won't later find a volume OR the external drive until I first put a CD in the drive, then power cycle the laptop. Yes, SCSI probe etc. have been tried, the device isn't even found on the bus by any of those apps unless a CD is present at powerup of the laptop, even if the external drive is on but empty. Every periph. I own is SCSI, I have more little widgets and ways to get things connected than I can believe, plus some special auto-sensing terminators, but I exhausted all my resources and now just put the CD in the drive before I fire up the laptop. I don't think the powerbooks SCSI implementation on these models is "quite right". Yes, I know about the termination power issue with Powerbooks that have IDE internal drives (see the lowendmac.com entry for any of these powerbook models). I also know that all Apple branded CD-COM drives/cases should be supplying SCSI term. power just fine, so it should not be an issue. I'd like to try a PCMCIA SCSI card sometime and see if the problem persists. I would bet it does not. So before you give up, try that out, if you haven't already. Holler if it works.
