I got into VM when it was CP/67 in 1970 and it certainly has been a fun
ride. One of my first tasks was to use O/S PCP to run multiple O/S jobs
under CP to justify the box. This was about the time Aetna started a
project to implement O/S MVT. In mid 1971 I moved to Eastern Airlines and
lost the
Does look like z/OS guys can read stuff off after a formatting write
though. They told me they found addresses and other such corp
properties data with their utility (DSS?)
So probably not good enough for Alan :)

Its been talked about, but there's like a 1100 volumes in production
(and their 1100 mirrors). And only a handful of tdisk volumes... The
coding is way easier without having to figure out where we stashed the
tdisk vols.

Yes, it is a formatting write. There are no more records on each track
after Record 1.

I presume that it was done as a formatting write so that there are no
more visible fields following record 1. That would at least be a logical
erasure of the rest of the track. If that satisfies Chuckie, or even if
it satisfies Alan, it is all right with me for them to use the fast
erase method.
It was a "special" everywhere. The HPO features for PERFORMANCE were bundled
into SP6 to restore performance lost in the move from SP5 because of all the
extra's as confirmed by the announcement letter:-

VIEW for VMWare for z/VM implies directory management and security
interface, as well as other z/VM functions. Probably zPRO is closer to
the requirement for that.

I'de be surprized if CP would only write 1 4K record per track: 180 4K
records fit on a 3390 track, and CP will surely remove all data.
You could use DDR PRINT to find out, or use DITTO if you've got it.

Have you tried to define a T-disk and run DDR to see what had been done
without formatting the disk? I see where it says that binary zeros are
written, but it doesn't say how many. I suppose it could do a formatting
write and just write one record of any size. I don't know if that would

We have XRC choking on a VM tdisk volume. Its mod 3 - tdisk 1-3338.
When clearing Tdisk, does VM write 1 4096 byte record per track? XRC
