And let's not forget the `32, a Seagate ST251[-1], which does
not appear to be modified.

BTW, we recently had trouble replacing RD54s in VS2000 systems.
A 3rd party sold us some XT2190s; some worked and some did not.
Strangely enough, we received two drives with sequential serial
numbers, of which one works and one does not -- bizarre!

The vendor sez that Maxtor sez the modified XT2190s were overrun
and got randomly distributed -- you're lucky if you stumble on
the modified ones.  Anyway, this vendor is the first we've had
these problems with.  They can't deliver any more drives guaranteed
to be RD54 compatible.

Anyone know the real scoop on the RD54?
