I was told to lock the heads in the rx01 and rx02
drives.
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. AFAIK, there is no
need to lock RX heads when moving them - there is nothing in the manual about
RX drives being shipped from DEC with the heads locks.
are there any good guides or sites with lots of
pictures of the drives
taken from different angles apart so i can get a better idea of what im
going to be working with?
Not that I know of, but the DEC manuals (mostly available online) are adequate.
Also, people tell me getting the drives off the rails
and out of the
rack is a pain, where would i find the appropriate information on how
to do that?
See above.
I really don't want to take the drives out of the
rack, but if it comes
to it, i would like to know how.
That's very wise - my last removal, it _really_ helped that I had read the
DEC manuals before-hand, as I wound up performing a removal I hadn't planned
on, and that had a tricky step I probably never would have found on my own,
but which I had luckily read about in the manuals.
Good luck on the move!

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.
