Aah- SCO UNIX, how fun. Have a XENIX box that I was trying to do the same thing with. SCO's partition table (DIVVY) is not read by Linux or indeed any other UNIX but SCO. Furthermore, SCO is one of those lovely companies for which headers are a part of the optional development environment, and TCP/IP is another add-on (how do they stay in business whan put against xBSD/Linux? the FUD about IP doesn't work against BSD- been there, done that, adjudicated non-infringing). The best way to get information off of one of these systems is to TAR an archive out to a raw hard disk. Then you can untar it on another UNIX system. UUCP could also work - haven't tried that route.
