The drive means that it has no wrt_prot parameter Johnny..

Trust me, I'm try to read things that are available before I ask.

I've learned about the drive internals since one of them was bad when I got
the machine, none of them was booting something, had tried that first and
so I ran erase and test utils in the drive. That was months before now.
I know that the drive hat an error in his logs but I've cleared that error
after running the drive tests and exerciser as described.
(I think tere is a rubber bumper in the drive that glued on the head
assembly and with google I found the "solution")
There was no time previously to try to install VMS.

No the thing is that I know almost nothing about VMS (and RSX11), I'm a
unix guy as you know.
People on the net organized almost w/o any effort from me that I got this
VAX4000/300 to give it a good home, now I have some free time and I'm
trying to install it after cleaning and repairing that !§$%%&/&%i!! PSU.

In the meantime as I write this I have run the drvexr task for 20 minutes:

 4188 operations completed.
75150 LBN blocks (512 bytes) read.
25050 LBN blocks (512 bytes) written.
81900 DBN blocks (512 bytes) read.
27300 DBN blocks (512 bytes) written.
75150 LBN blocks (512 bytes) read.
    0 bytes in error (soft).
    0 uncorrectable ECC errors.

Have you an VMS mount command handy that I should try?
