DEC RK05F videos and pictures - running it naked!

    I would be more conserned with getting my long hair
caught in the disk. 
 Which would certainly cause a headcrash... (Note I didn't say which head
 would crash and into what ;-))  
 I've been told by my local DEC field engineer that the heads don't get in trouble
with big stuff 
 i.e. everything you can see. That's just kicked off the disk - dangerous is the stuff
that fits 
 under the heads... Hair does not fit under the heads. 
My comment could also be taken to mean that if hair attached to you head 
gets caught in the drive mechanism, then _your_ head will crash into some 
prt of the drive chassis. 

But anyway, getting back to the normal sense of 'headcrash', I am not 
brave enough to try dropping a hair on a running RK05 platter to see what 
happens (Yes, I have spare heads and the alignment pack, but I am not 
goign to waste them). It might well be alright, but I am not going to 
risk it.

...

 Oh, that bad RK8E controller just confronts me with "Data break error" :-(

IIRC a ;'data break' is a bit like DMA. I do haev the prints and some 
technical desription, so I could help you debug this sometime...
