When run COPYSL will perform command line argument validation and display |
|
|
|
an error if they are illegal. Also any disk IO errors will cause COPYSL to exit. |

When specifying slice number(s) a check is made that the slice number is |
|
|
|
valid, i.e. not too large that it would extend past the end of the |
|
|
|
partition (hd1k), or the end of the media (hd512). For hd512 a check is |
|
|
|
also performed to ensure that the slice would not extend into the first |
|
|
|
defined partition. |

The copy operation will be faster if the source disk has been formatted |
|
|
|
with the CP/M file system, since during copy the CP/M directory is scanned, |
|
|
|
and unused blocks are not copied. |

Verification (if option chosen) will do an aditional read (after write) |

and compare the data read matches what was written. This compare is only |
|

on every 32'nd byte. This is done for efficiency. |

Each "." represents 16 kBytes of data copied. Each line of "." 's is 1 mBytes. |

Testing |

------- |
|
|
|
This tool has been tested on both SD and CF media types and with hd1k and hd512 |

|

formatted media |

History |
|
|
|
------- |
|
|
|
* v 0.1 Initial Release |
|
|
|
* v 0.2 Added the /v command option to read and verify after write |
|
|
|
|
|
|
|
Future |
|
|
|
------ |
|
|
|
* support a verify option to read/verify data just written |
|
|
|
* support ability to read and write from image files stored in CP/M filesystem |
|
|
|
* maybe the verify options could allow more complete verification. |
|
|
|
This would be at the cost of performance |
|
|
|
* ability to abort once the copy has started <ctrl><c> |
