Will it boot with the drive attached but powered off? Once you have the Plus booted up, then you can switch on the power to the external drive and launch appropriate formatting software.
It worked, thanks. Now how long will it take a 2GB SCSI drive to format at low-level?
Whewww, using the Mac Plus's SCSI port? Probably within a few sigma of forever... Seriously, I think the Plus SCSI operates at something like .75 MB/s and I have no idea what kind of overhead is involved in formatting, but it seems like it would be somewhere in the neighborhood of 3000 seconds theoretical at least, so probably an hour or two. Maybe more.
Let us know. That's an interesting question. I just bought eight IBM Ultrastar 2ES 2 GB drives with 50 pin interface, so I may need to know the answer my self soon.
It would probably be faster to have an SE or Classic format the drive, if you have one handy. I know that with APS PowerTools, at least, setting the interleave is a user accessible function. Although, I also remember that someone on this group stated that on more modern drives you don't need to set the interleave for the Plus? Anyone remember the details? It had something to do with modern buffering or some such.
