Same here.  Though I have some TLZ04s that seem to behave well.

Same here but I got the RD53s as "bad" and opened and fixed them.
I also ahve TK50s (on sleds) and the boxed TK50 in both the DEC
sorta scsi flavor.

Back when 1GB drives were free and easily found I got a bunch 
along with a stack of RZ55s and 56s (with BA42 storage boxen).
so that was the simplest and fastest solution for my systems 
with SCSI (all of the 3100s and one BA123 uVAXII).  The others
(BA23 uVAX and uVAX2000s)  I use RD53s and 54s for that.
