    I'm looking for the Original name of a pair of CPM disk copy utilities that from copy from DOS to CPM and Back
    My old IBM 5160's HDD croaked (Not too bad after 37 years)
    I use this machine to make boot disks for various old machines and I "thought" that I had a backup of everything on the machine but it seems my CPM utilities are missing they were in a directory that didn't get backed up and I DO NOT REMEMBER the name of
    the original utility the files came from.

    When I google CPM to DOS I get results for "CPMTOOLS" <-I don't want that

    The utility I used had 2 separate .com files one to read from cpm one to write to it and it was all command line.
    To compound matters I had renamed the original .com's so I don't remember what they were originally called.

    My renamed COM files were called CPM2DOS and DOS2CPM
    and from my notes the syntax was

    CPM2DOS /(DEC1,OSB2, KAY1,TRSA,etc) A:*.* C:\CPM
    DOS2CPM /(DEC1,OSB2, KAY1,TRSA,etc) C:\CPM\*.* to A: \

    Don't know if anyone might recognize the original files from my renamed files syntax from my notes.
    I have a list of all the 4 digit codes that it reads and writes if that helps..

    Thanks in advance!

    Following up: 22disk contains two programs, ctod.exe and dtoc.exe that actually do the file copies, but you will need a file called cpmdisks.def that is a "database" of the diskette geometries (keyed on that 4-character system identifier). There are
    also a couple of utilities (genindex.exe and stripidx.exe) to help with generating your diskette definition file.

    There is also a program (cdir.exe) used to display the directory of the CP/M diskette.

    Sounds very similar to the classic Sydex utility, 22disk. It used 4-character system identifiers. You might have extracted the copy executables from the 22disk structure? It had options to assign drive formats, copy, and display the diskette directory,
    etc.

    See if you can find a copy of 22disk on-line somewhere and take it apart. I bet it will work for you.

    Thanks in advance!

    Sure thing!

    Roger THANKS!!!!!
    After looking at your second post I searched the backup of the drive and found those two files you mentioned. I must have done the backup BEFORE I renamed those 2 files and changed their directory and that backup was dated over 10 years ago!!
    It was indeed 22disk and the two files I renamed were the CTOD and DTOC I made em easier to read CPM2DOS and DOS2CPM!!
    I wrote all that down in my notes now and I saved a new backup with the renames and the new directory.
    Its funny how subtile changes to the filenames and directory can cause fits!! but it made my life easy... for a short time LOL!
    Again thanks for the memory jog!!!

    And all this started because I was making a couple Osborne 1 disks for a buddy!

    well, the largest HD ATTF (Actual Time To Fail) I personally recorded is
    10 year, so if you got an ATTF of 37 years from an HDD, well, this is a
    major feat.. manufacturer and model ?

    and how you lost these files because of a 37 y.o. HDD crash, well, why
    you haven't backuped your HD ?

    Best regards from Italy,
    dott. Piergiorgio.
