Things to watch out for:
1) External drive must supply termination power (the power supply in the Plus is too feeble to do the job, so the design team decided that the external box should supply term power).
2) Large capacity drives will often not allow formatting at 3:1 interleave. In the context of the Plus, "large capacity" may be anything from 500MB on up (the exact value depends on the make and model of the drive).
3) Large capacity drives may not work properly as boot volumes for the Plus, even with the last rev of ROMs. I have a 1GB Seagate drive that boots newer models fine, but will not work with the Plus. I gave up trying to figure out why, but it appears to be related to the lack of hardware handshaking in the SCSI implementation uniquely used by the Plus.
