Probably between 30 and 45 seconds. I haven't timed it.

It is always the same. I think that maybe the drive thinks the disk is
not coming up to speed fast enough.

Yes, once I cycle power to the drive to clear the fault light. I wish I
knew a cleaner way to reset the fault light.

The label claims that the disk holds 'Stand-alone Forth', which may be
interesting. The ready light never comes on, just the fault light, so I
don't think I could INIT it if I wanted to.

The machine is a PDP-11/24 with one RA-80 and 2 RL-02 disks, 1024 KB
RAM, FPU, EIS, DZ11A. Running RSTS 9.2

$9.95 plus $12.50 shipping.
