Yes, that was a feature. You had to reformat it, which required getting the timing track
writer box from Maynard. I have seen that done on an RS11 (RF11) drive on our RSTS
system; it crashed some heads and was rebuilt completely (new heads, new platter, new
motor).

Then again, I remember our college RS64 (drive for the RC11) which developed a bad motor

Nice of the FE to do that.
The Univ. of Wisconsin CS Department had one of those, but the platter
went bad. They just flipped the platter upside down and got more use
out of it. The Univ. of Wisconsin ECE Department also had one -
the two machines
were nearly twins. I *have* *that* one - and it still ran when I tried
it a year or so ago.
Neat. You can run RT11 on it if you add the boot loader and driver, at least old
versions. DOS V4 also supports it. And older versions of RSTS can use it as a swap
disk.
