- CMCopy: A Program for Making Multiple Diskette Copies
- by Charles F. Martin
-
- Usage:
-
- CMCopy first reads a disk from either floppy drive A or B, as
- chosen by the user, and makes an image of it on hard drive C. It
- then asks you how many copies you wish to make, and whether you want
- to verify each track after it is written. (During "verification"in
- CMCopy, the disk drive reads the track it just wrote, calculates a
- CRC -- "cyclic redundancy check" -- and compares it with that
- recorded on the disk during the write operation. Modern diskette
- drives are so reliable that this extra step is not really necessary,
- unless the copy is so valuable that you want a small amount of extra
- assurance that it is exactly correct.)
-
- Running:
-
- At the DOS system prompt, just type CMCopy. You will be shown an
- opening screen that may be cleared with a single keystroke. CMCopy
- then asks you to press the letter, A or B, corresponding to the
- drive you want to read from, to insert the master disk into the
- drive, and press Enter. CMCopy will then read the disk, first
- determining and informing you what disk format it is.
-
- After successfully reading the master disk, CMCopy will ask how
- many copies you wish to make, and offer a "default" value of 10.
- Adjust the default value of 10 using the "+" and "-" keys, and, when
- the number is correct, press Enter. (If you don't know how many
- copies you want to make, or you enter a wrong value, don't worry.
- After each copy, CMCopy gives you the option of inseting another
- blank disk and pressing Enter to start the next copy, or pressing
- <Esc> to terminate this run of copies.)
-
- After a run of copies, CMCopy first offers you the option of making
- more copies of the same master disk, and, if no more are desired, of
- reading a new master from either drive. Answering N to both
- questions leaves the program.
-
- Automatic Formatting:
-
- CMCopy determines whether the blank disk being copied to is already
- formatted in the format of the master disk, and performs the format
- if required. FOR 3.5" DISKETTES, there is a hole in the diskette in
- the corner adjacent to the movabale write-protect slide if the
- diskette is capable of high-density (1.44Mb) format, and no hole if
- it is 720kb. The case style of the blanks to be copied MUST MATCH
- the case style of the master disk, or format errors will occur.
-
- Error Detection:
-
- CMCopy reports any error returned by the BIOS (Basic Input/Output
- System) diskette services, and the operation during which the error
- occurred. The following is a listing of the errors the BIOS may
- report, in hexadecimal format, as relayed by CMCopy. It is
- included here for completeness. CMCopy will ask you if you want to
- try another master if an error occurs during disk reading, and will
- advise you not to use the copied disk if the error occurs during
- disk format/write/verify:
-
- Error Code: Error Description:
- 02h Address mark not found
- 03h Attempt to write on write-protected disk
- 04h Sector not found
- 0Ch Media type not found
- 20h General controller failure
- 40h Seek operation failed
- 80h Timeout (no disk in drive)
-
- Errors 02h and 04h signify defective or unformatted media. The only
- error you will likely ever see is 80h, if you forget to put a disk
- in the drive.
