Power Mac 7100/66 hard drive question

[Idexpert]

Hi, I have a Power Mac 7100/66 hard drive and wish to use it with Power Mac 6100/66. But I am not sure if my Power Mac 7100/66 hard drive is compatible and will work on the Power Mac 6100/66 computer.

Will my Power Mac 7100/66 hard drive work on a Power Mac 6100/66 computer?

Yes.

...as will almost any other SCSI hard drive, if you use appropriate adapters.

Correct, a SCSI drive is a SCSI drive.

For a while, I ran a circa-1999 10,000 RPM Ultra2 SCSI drive in an SE/30.

And there is nothing preventing a modern 15,000 Ultra320 SCSI drive from working externally on a Mac Plus, or internally in an SE or II. (For internal use, you'd need a physical adapter, since modern parallel SCSI drives use either 68 or 80-pin connections; but those adapters are just physical converters from 68 or 80 pins to 50.)

Except for the occasions when it doesn't work.

The Plus tends to have trouble with drives over about 1GB (it's not the capacity as much as newness). Booting from them is often impossible, for one thing. The timing loops used by the Plus's SCSI implementation (the Plus is unique in its lack of SCSI hardware handshaking) apparently cause this behavior. I wish there were a patch to solve this problem -- it would be great to have a gigundus, bootable drive for my Plus!

The 6100 and 7100 had the same minimum OS 7.1.2 so a HD from one should run fine in the other.
