[net.decus] MicroVAX II

dave@helm.UUCP (David Goldblatt) (07/31/86)

[ Here it comes just a walkin' down the street, singing "eat me.. eat me.." ]

	At my place of employment [not helm - I just leach their computer]
we have a MicroVAX II, 71Meg drive, and sometimes one TK-50 tape drive.
Has anyone besides me had grief with the TK-50?  Ours failed one day [more
than once, but this was the final straw..] when the leader slipped off,
which from what I hear is a common occurrence, and promptly shredded itself.
It is now somewheres in Illinois being fixed by DEC.  We had a temporary
drive installed, and 45 minutes after installation, it too died on us. 
Fortunately, we managed to fix it [leader got hung up].  Does anyone out
there have any recommendations on alternatives to the TK-50?  Unfortunately,
it is DEC's media distribution method, so we're not going to be able to
rid ourselves of it, but basically I need something to frequently back up our
hard drive onto.  Any info would be appreciated.

Consider this a ditto to just about everything you said.  I have no answers;
I just like to share my misery.  Between DEC's lack of interest in fixing an
obviously unacceptable situation with their TK50 and their total lack of
interest in providing a disk formatting program (I think they MIGHT let us
have one for THOUSANDS of dollars), I find it difficult to become a DEC
enthusiast.  I'm still trying, though.  (I KNOW I am; everybody TELLS me!

	We have had no trouble at all with the 5 tk50 drives that i have
to work with.....we did have a LOT of trouble with the second batch of
tk50 cartridges....As I understand the problem:

	3M made the first large production run exactly to Digital specs...and
they worked fine...Then, in a cost cutting move, they changed the formulation
of the glue holding the leader to the tape itself...and they blew it...it
degraded and let go and gummed up the works...etc,etc...

	Well Digital was furious and forced (??) them to recall all of them..
Since we have gotten the new batches, I have not had any problems at all...

	(note: we only use them for backup and software distribution)
	(note2: also, when using backup, explicitly use as large a block
		size as possible....I have found that vms backup with a
		block size of 32000 and 5 buffers will back up a 71 meg 
		disk in about 15 minutes...)
