4421.1really, any ideas here ?NPSS::BENZI'm an idiot, and I voteMon Feb 24 1997 18:3120
    No one ever answered Abdelhakim, but I'll ask the question again.
    
    Is there any way to directly copy files to/from a 4mm TLZ06 drive under
    Windows NT ?  I had no luck attempting to use the 'COPY' or 'DIR'
    commands with \\.\tape0 - what can use that nomenclature ?  Only fopen
    within a program ?
    
    I'm mostly using the wintar95 package (the TLZ06 seems to need the
    non-blocking tarnb.exe version), and it comes with 'mt' to manipulate
    tape positioning, but every once in a while, I might want to move a tar
    file from one tape to another without bothering to unpack/repack.
    
    I asked this under the wintar95 topic in WINDOWS95, and the only
    suggestion there was software from Seagate and/or HP - Seagate sells it
    for $90, HP has an HP only (non-scsi) version for $19.  But it doesn't
    mention NT, nor Digital drives (the Seagate list of supported drives
    probably does list the TLZ06 under it's OEM name, but I'm not sure - it
    isn't relevant, 'cause I can live without if it's $90.)

re .2


	Under OpenVMS COPY/DIR uses the ansi tape format.

	Under NT there is a backup/restore program that doesn't
follow any standard. There are a few public domain TAR programs.

NetWorker for Windows NT can perform a tape to
tape copy operation; of course, as with standard
NT backup, the tape format is proprietary.

    so, is \\.\tape0 only usable from within MS C++ ?

re .4

	"is \\.\tape0 only usable from within MS C++"

	No. any programming enviroment that can call Win32 can open
\\.\tape0 ( Fortran, Visual Basic, ... ). This interface gives you
aceess to the raw tape device ( not Ansi Format ). Also Windows NT
puts the drive in fixed block mode by default. You will need to do
a few IOCTL calls to get the drive in varibale block mode that is 
required for Ansi format.
