At least you are able to backup your hard-disk to floppies. This is what I currently do, and I was forced to modify my modified floppy driver (ST) to access raw floppies on other inodes than the ones used for floppies containing filesystems. Now I have both, automatic recognition of disk-geometry for normal use and raw hardcoded floppies ( 10 spt, 11 spt, 9 spt, cylinders from 80 to 84) for use with the pax/tar/cpio utility that I am currently beta-testing. For those who want to know more: tar/pax/cpio supports multiple volume archives, and it can't tell the filesystem to create a new file on the newly inserted disk... Maybe, after getting pax/tar/cpio to work flawlessly (bugs are very few by now) I will try to work out a solution for that problem. But I intend to post results as soon as beta-testing-period is over. --Jan-Hinrich ============================================================================== Jan-Hinrich Fessel , University of Dortmund, Computer Science Dpt.
