9: .SH NAME
10: rxformat \- format floppy disks
11: .SH SYNOPSIS
12: .B /etc/rxformat
13: [
14: .B \-d
15: ] special
16: .SH DESCRIPTION
17: The
18: .I rxformat
19: program formats a diskette in the specified drive
20: associated with the special device
21: .IR special .
22: (
23: .I Special
24: is normally /dev/rx0, for drive 0, or /dev/rx1,
25: for drive 1.)
26: By default, the diskette is formatted single density;
27: a
28: .B \-d
29: flag may be supplied to force double density formatting.
30: Single density is compatible
31: with the IBM 3740 standard (128 bytes/sector).
32: In double density, each sector
33: contains 256 bytes of data.
34: .PP
35: Before formatting a diskette
36: .I rxformat
37: prompts for verification if standard input is a tty
38: (this allows a user to cleanly
39: abort the operation; note that
40: formatting a diskette will destroy any existing data).
41: Formatting is done by the hardware.
42: All sectors are zero-filled.
43: .SH DIAGNOSTICS
44: `No such device' means that the drive is not ready,
45: usually because no disk is in the drive or the drive door is open.
46: Other error messages are selfexplanatory.

53: .SH BUGS
54: A floppy may not be formatted if the
55: header info on sector 1, track 0 has been damaged. Hence, it is not
56: possible to format a completely degaussed disk.
57: (This is actually a problem in the hardware.)
