I hooked up a 9122 flexible diskette drive to my 9000/375 machine, and am trying to use "mediainit" to format the floppies. I can't find any documentation on the -f format options...can anyone tell me what the supported options are and how (if at all) they correspond to what the rest of the world (DOS, Xenix, SunOS) calls DS/HD or DS/DD diskettes??? (Oh, by the way: HP-UX 7.0) please send email and I'll summarize the info here. Thanks. -- Jim Morton, Applix Inc., Westboro, MA ...uunet!applix!jim jim@applix.com

(Oh, > by the way: HP-UX 7.0) Here is the table of floppy formats historically supported by HP workstations. The current HP 9122C (HP-IB, SS/80) drive supports all of them, although the Vectra does not, nor does the 9114B portable disk drive. ___________________________________________________________________________ | Format | | SS/80 | | Bytes/ |Sectors/| Tracks/ | | | Name | Media | Option | Capacity | Sector | Track | Side | Sides | |===========|=======|========|===========|========|========|=========|=======| | HP Single | Blue | 4 | 270,336 | 256 | 16 | 66(+4) | 1 | |-----------|-------|--------|-----------|--------|--------|---------|-------| | HP 630K | Grey | 0 or 1 | 630,784 | 256 | 16 | 77(+3) | 2 | | HP 710K | Grey | 2 | 709,632 | 512 | 9 | 77(+3) | 2 | | IBM 720K | Grey | 16 | 737,280 | 512 | 9 | 80(+0) | 2 | | HP 1K | Grey | 3 | 788,480 | 1024 | 5 | 77(+3) | 2 | |-----------|-------|--------|-----------|--------|--------|---------|-------| | HP 256/HD | Black | 0 or 1 | 1,261,568 | 256 | 32 | 77(+3) | 2 | | HP 512/HD | Black | 2 | 1,419,264 | 512 | 18 | 77(+3) | 2 | | IBM 1.44M | Black | 16 | 1,474,560 | 512 | 18 | 80(+0) | 2 | | HP 1K/HD | Black | 3 | 1,576,960 | 1024 | 10 | 77(+3) | 2 | `----------------------------------------------------------------------------' Blue: Single-side "1/2 Mbyte" density.

The documentation you need is squirreled away in /etc/disktab. It has a rather lengthy dialogue about microfloppies and all possible options. /etc/disktab is meant to be read by people who need more information about disks. Cheers, Paul Perlmutter

Please see the section "A word about microfloppies ..." in "/etc/[newconfig/]disktab". Obvious place isn't it ? :-) Frank Slootweg, HP, Dutch CRC.
