- Charles is right. The DEC formatting software can indeed format an
- ST225 (whatever approx. 20M capacity drive they offer works, probably
- the RD-31). Anyway, I know because I did it long before I ever got my
- hands on Wutil, though that would certainly work too. As to whether an
- RD-31 is actually a DEC relabelled St225, probably, but who knows!
- I remember hearing that DEC wanted an astronomical price for their
- relabelled drives, but that is another story. And besides that, my
- second hand ST225 didn't live long :-(
