[comp.os.msdos.programmer] Reading HP instrument disks on a PC

J.A.Jones@lut.ac.uk (Jeff Jones) (05/21/91)

Hi

We have a number of Hewlett-Packard instruments, many of which have
built in floppy disks for the storage of measurement data. It would be
very useful to be able to read these disks on a PC. The various manuals
say that the disks are readable on HP9000/200 and HP9000/300 under
BASIC 3.0 and 4.0 but they do not give us the disk format. All the
manuals give the stored file format but this is not useful if you can't
read the disks !. We have no access to an HP9000 computer within our
institute and hence would like to use a PC compatible to read these 3.5
inch disks. Does any body know of any utilities, PD or commercial, that
will allow this ? alternativly if someone knows the disk format, or a
reference to it, we could have a go at writing such a routine
ourselves.
Thanks for your assistance in advance.
			Jeff

There is a company called Oswego Software (or something like that) that
markets a utility that runs on a DOS machine and reads floppys generated by
an HP instrument.  I would have liked to have used it, but at $495 a copy I
found an alternative solution.  You might check with your local HP rep -
they were the ones that put me on to this outfit.

I use ANADISK, found on simtel20 and wuarchive in the msdos/dskutil 
directories.  It is a little clunky to use, but for a $25 shareware fee,
it provides huge bang for the buck, and has worked extremely well for us.

It doesn't completely convert the disk, but it does cope with non-PC
sectoring and generates a file image of the floppy (with an optional
embedded sector map), which you then can manipulate however necessary.

The format of the disks is something that was designed by HP in the late
'70s and is called LIF, short for Logical Interchange Format.  It is a
flat file system, consisting basically of a two sectors (I believe) "header",
mostly containing just a volume label, directory size, and a couple of other
things.  Then comes the directory, which contains name, size, and location
of start of file on disk information (amongst other things).  The directory
is then followed by the data sectors, with all sectors of a file contiguous,
making the files non-extendable.  There are many different file formats of
course.  HP sells a utility (called something like "The LIF-MSDOS Utilities"
or some such, that will allow you to read/write LIF disks on a DOS computer,
translating various LIF file formats to DOS files.  I don't know a part
number, but an HP sales rep could probably track it down for you.
