I have source to both PDTAR and PAX but have not yet attempted to compile them under MS-DOS. Looking at the source, I suspect the only thing these programs will be able to do is write tar or cpio archive files on an MS-DOS filesystem. I would prefer them to write RAW, non-filesystem floppies, so I can read multivolume backups created on DOS, on a *NIX system without using doscp or the like. Is there any way I can accomplish this? Please bear in mind when replying, that my knowledge of MS-DOS internals is almost zero. -- Pim Zandbergen domain : pim@cti-software.nl CTI Software BV uucp : uunet!mcsun!hp4nl!ctisbv!pim Laan Copes van Cattenburch 70 phone : +31 70 3542302 2585 GD The Hague, The Netherlands fax : +31 70 3512837

Yes. The MKS Toolkit includes a dos version of the Unix "dd" utility, which can be used to redirect stdout to raw floppy. The only trick is that when you use multiple disk types in the same drive, "dd" assumes that the floppy you are using as a raw device has the same physical characteristics as the last floppy used in a file operation on the same drive. I don't know if there is a free version of "dd" for dos available, but the MKS version works nicely for this purpose. ------------------------------------------------------------------------ Ken Mitchum MD KY3B Decision Systems Labs University of Pittsburgh km@cadre.dsl.pitt.edu

PAX with the MSDOS patches I posted to comp.sources.bugs does RAW nonfilesystem floppy reads and writes for compatability with UNIX. It also can use the MSDOS filesystem. It is also free. For those of you who don't know PAX groks BOTH tar and cpio. EXE's posted to comp.binaries.ibm.pc available from simtel20 available via anonymous ftp from 192.31.83.2 vms.ucc.okstate.edu SRC pax source posted in comp.sources.unix (or comp.sources.misc??) patches to pax by the author in comp.sources.bugs my MSDOS patches in comp.sources.bugs already patched source from 192.31.83.2 vms.ucc.okstate.edu with ftp PAX v2.0 is in currently in beta test and will be posted next year. -- Harold G.
