| 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 | |
| 7ae62f7c | 24 | is normally /dev/rx0, for drive 0, or /dev/rx1, |
| 05b75eac KM |
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 (this allows a user to cleanly | |
| 38 | abort the operation; note that | |
| 39 | formatting a diskette will destroy any existing data). | |
| 40 | Formatting is done by the hardware. | |
| 41 | All sectors are zero-filled. | |
| 42 | .SH DIAGNOSTICS | |
| 43 | `No such device' means that the drive is not ready, | |
| 44 | usually because no disk is in the drive or the drive door is open. | |
| 45 | Other error messages are selfexplanatory. | |

| 50 | .SH BUGS | |
| 51 | A floppy may not be formatted if the | |
| 52 | header info on sector 1, track 0 has been damaged. Hence, it is not | |
| 53 | possible to format a completely degaussed disk. | |
| 54 | (This is actually a problem in the hardware.) | |
