Yes, I've done that already.
It seems that the disk has some problems, or better the two RF31 disks.
If I try to install VMS on the disks there is some ratteling and data where
copied to them, after a while I get those infamous "volume is not software
enabled" errors.
There are no problems detected from the dssi internal support programms or
their logs...

I've erased the disk dia0 again with the dssi tools since that overwrites
every sector o nthe disk (for data security reasons) and I get no error.
Now hours later I've tried to install again. (backup/image/verify
dua3:vms073.b/save disk0$dia0:) The backup starts to shuffle data and then
bails out with that:

%PAA0, Port has Closed Virtual Circuit - REMOTE SIDE DISK0

%BACKUP-E-WRITEBLOCK, error writing block 237 of
NV, volume is not software enabled
..followed with all next blocks.

I have a real 
VT420 connected an must copy all the things per hand...

I think that there is  some hardware error on the disk but not related to
the disk surface, more some positioning error or something like this.
Maybe changing some electrolytics will help here?
I've checked the disk with the exercider and dsktest more then one time,
there is NO error at all.


I'll check waht you've suggested tomorrow.. had two scotches an two beers
in the meantime..
