so I sorted through my last weekend's bait, hooked
up my new HSZ40
(with 50 GB in 4 StorageWorks boxes plus all sorts of tape drives,
TSZ07, TLZ07, TZ68, and ~88) to my PC for FreeBSD. It's so much
fun to read a 9-track reel from a FreeBSD PC (just too bad it doesn't
have a transparent top cover to show off the reels).
I have bulk-erased a bunch of TK50 tapes in the hopes that they
would work as DLT III and IV tapes as well, but these drives
still went into write-protect mode. Does anyone here know details
about the DLT media? I mean it is a well-known fact (and I proved
it to myself many times) that CompacTape I works just fine as
CompacTape II. So why not as III and IV? Is it really the tape
or might it be some notches on the cassette that are used to
code the kind of tape?
The problem is I didn't get any tape media for my nice DLT tape drives
and this stuff is so darn expensive if bought new. Any ideas?
I really hope you didn't wreck that TZ86 and TZ88, thankfully these are the
DEC drives and I think they might be more forgiving than something like a
DLT2000 or DLT4000 drive. IIRC, the TZ86 is capable of reading TK50 and
TK70 tapes. There is a drastic difference between TK50/70 and DLT III & IV
media! I don't remember the specifics on the differences, part of it is
that it writes in a different manner, and part is that the tape is
different.

To add a some info. as to a near answer to this question, I was able
to _read_ TK50's into an Alpha with a ~20GB DLT drive (don't recall
the designator) back in 1997 when that drive was nearly new. I don't
believe that the newer drive had any chance of _writing_ reinit format
information (after a bulk erase) onto such a tape.

One DLT2000 drive I have is also labelled "Not TK50/TK70 certified". The
implication of the label is that there may have been drives produced
with better backwards compatibility.
About newer DLT media: I've seen varying prices for the tapes on EPay,
ranging from "good deal" status to "I'm sure I could find them new for
that price!!". YMMV...

Hey Zane, I may be a UNIX weenie from your perspective, and I did take
a day or two before I explored the DEC7000, and it will not run VMS,
but I am not so crazy as to "wreck" good tape drives :-) I just wish
the 20GB tape media wasn't almost as expensive as a 20 GB hard drive
:-)

I didn't say "this type of machine can't run VMS", I said "this
machine will not run VMS" (and forgot to say: under my hands.)

I may be mis-parsing this, but I can certainly confirm that a DEC7000 will
run OpenVMS. I used to manage a VMS cluster that had two VAX-6620s and a
DEC7740 all running OpenVMS 6.2 very nicely.
