Intersting problem popped up this afternoon. Need to copy floppies used in an HP-9122C configured as an automatic test station. Any ideas? Best I can tell they are 3.5" "low density" (not 1.44M) with 1024 byte sectors. Don't know if 1-side or 2-side. People who operate the machine don't know how to copy floppies. Prior generations didn't document it, but did proceed to lose the manuals. Looking at "man fdc" and "man fdformat" I see support for 128, 256, and 512 byte sectors. Attempts to read this floppy under FreeBSD failed. SGI's Irix was able to read it (with dd) but so far I don't have a clue as to formatting a new blank. Does PC hardware support 1024 byte sectors? Could I simply hack it into my kernel and fdformat? dd on Irix read about 400k off one floppy, 600k off another. Browsing the raw data it appears I did get real data off the disk. Have no need to make sense of the data, only want to dup the disks. Don't have access to a generic HP system. This one is hard wired and the floppies are coded as a dedicated test station of some sort. A FreeBSD solution would be nice. A DOS solution would be acceptable. -- David Kelly N4HHE, dkelly@nebula.tbe.com ======================================================================== Whom computers would destroy, they must first drive mad.
