💾 dskdump(1) — sector-level copy from one floppy or image file to another

okay so this is the dskdump(1) page from the Emulators manual, and it is literally here to copy a floppy disc or image file to another floppy or image file — optionally converting image types. bestie, this one is lowkey powerful 💅

🌸 NAME 🌸

dskdump — sector-level copy from one floppy or image file to another. it’s giving “same data, different floppy/image” energy, no cap 💖

✨ SYNOPSIS ✨

dskdump [-itype TYPE] [-otype TYPE] [-iside SIDE] [-oside SIDE] [-icomp COMP] [-ocomp COMP] [-idstep] [-odstep] [-retry COUNT] [-format FMT] [-first CYLINDER] [-last CYLINDER] INPUT-IMAGE OUTPUT-IMAGE

🦋 DESCRIPTION 🦋

dskdump copies floppy discs or images, optionally converting image types. unlike dsktrans(1), dskdump can handle discs with different numbers or sizes of sector on different tracks. that’s the whole vibe: sector-level copying with room for weird discs, and honestly? iconic 🫶

🎀 OPTIONS 🎀

okay bestie, every flag is here — no skipping, fr fr.

• -itype TYPE — picks which driver reads from the source disc. the choices are:
  • auto — select according to the disc image file. this is the default 👑
  • dsk — use the DSK (CPCEmu format) image driver.
  • edsk — use the extended version of the DSK format.
  • floppy — use the floppy driver.
  • myz80 — use the hard disk (MYZ80 format) image driver. (this format cannot be autodetected.)
  • cfi — use the CFI (DOS fdcopy format) image driver. (this format cannot be autodetected.)
  • apridisk — use the ApriDisk image driver (from the utility of the same name). (this format cannot be autodetected.)
  • raw — use the raw driver.
• -otype TYPE — picks which driver writes to the destination disc. the drivers are as for -itype 💫
• -icomp COMP — selects the compression method used on the source disc image file (has no effect when reading a floppy disc). options:
  • auto — detect from the first few bytes of the file. this is the default.
  • sq — Huffman coded (SQ / USQ).
  • gz — Gzipped (gzip / gunzip).
  • bz2 — Burrows-Wheeler compressed (bzip2 / bunzip2).
• -ocomp COMP — selects the compression to be used on output. compression methods are as for -icomp, except that bz2 cannot be used. noted, bestie 🎀
• -iside SIDE — determines which side (0 or 1) of the source disc is to be read from.
• -oside SIDE — determines which side (0 or 1) of the destination disc is to be written to.
• -idstep — double-step the source drive (used to read 360k discs in 1.2Mb drives). only supported by the Linux floppy driver.
• -odstep — double-step the destination drive (used to write 360k discs in 1.2Mb drives). only supported by the Linux floppy driver.
• -retry COUNT — set the number of times to attempt a read/write/format in case of error. retry era 💀
• -format FMT — do not autodetect the disc format; use the named format. dskdump does not make extensive use of the disc format; it is chiefly used to provide a guess at the number of tracks to dump.
• -first CYL — start copying at the specified cylinder. cylinders prior to this will not be formatted or written.
• -last CYL — copy up to and including the specified cylinder.
• -odstep — double-step the destination drive (used to write 360k discs in 1.2Mb drives). only supported by the Linux floppy driver. yes, bestie, -odstep is listed twice on this page — same double-step destination drive energy both times 💅
