The RL01/RL02 Users Guide (bitsavers.org/pdf/dec/disc/rl01_rl02) Figure
2-25 on page 2.35 describes the positioner restraining bracket that
should be put in place before shipping. It is just a little square
piece of metal (probably aluminum) with a single screw that holds it
down that sits in
Very good explanation, Tony!
Is there any chance that he might need to worry about a pack being inside the
drive with the heads un-parked, e.g. from an abrupt power failure?

I would hope not (IIRC all DEC drives are designed to retract heads if the
power fails). If the heads are still
Thank you all for the excellent information. I think i have a pretty clear

pack in the drive? What holds the pack in there? Can the pack be removed
without power?
Believe-it-or-not the pack is held to the spindle by

Subject: PDP 11 - how to lock heads in a rx01 and rx02 - seeking advice
I asked for advice a while back on
I made a mistake. I was reading about the floppy drive and accidentally
mentioned the rx01 / rx02. The hardware to be moved is actually RL01/RL02
hard drives, not the floppy drive. Please forgive the mix up, any help is
appreciated.

Once I do this myself i plan to put up a gallery of lots of pictures to
help another newcomer such as myself. Not having seen the actual hardware
is what gets me the most mixed up.

Err, I think we told you to lock the heads the RL0x's, not RX0x's; the former
use large rigid packs, the latter are 8 floppy drives.
Make sure the doors are shut. I used to tape them. Remove any floppies you
care about.
Some of the non-DEC 8” drives used to come with a cardboard blank.
But these were double sided disks and the blank was meant (I believe)
to prevent the heads from banging against each other.

I asked for advice a while back on what to expect with moving a pdp 11, I
was told to lock the heads in the rx01 and rx02 drives. I'M getting pretty
lost in all the information about the drives, are there any good guides or
sites with lots of pictures of the drives taken from different angles

No. The RX01 and RX02 are dual 8 floppy drives. There is no need (or way) to
lock the heads in those. Both are single head units, so there is no
See page 2-8 for a view of the packing configuration.

I find [RL0x's] easier than RK05s
Try taking out an RA81!
I did an R80 (not much lighter) single-handedly.
The trick with those is to take the HDA out. It takes only a few minutes. Raise
the logic chassis (top part of the case including the front panel), then
The RA60 is my least favorite drive to move. The thought of disassembling
it crossed my mind but since it was being slid into a rack with a shelf and
not on rails it would not have helped much, so just picked it up, carried
it over and shoved it in.

(Somewhere I have pictures of the rig I built to take a couple of RA81's out
of some racks I was sent. I should post them...)
