If you dont mind disassembling your vintage Mac, SCSI drives can be mounted with BasiliskII version 142 for Windows,

given you got some working SCSI HA installed in your Windows box.

I mounted an external HDD and some MOs that way, some time ago.

Of course this is only possible for HFS and not for HFS+ drives.

The DiskCopy way might be the easiest, though.
