Great stuff. Thanks. OK, using your command but changing it to the |
| 7 |
drive itself I got this: |
| 8 |
|

~ # isoinfo -d dev=/dev/hdb |

I then used dd to make a file: |
| 42 |
|
| 43 |
~ # dd if=/dev/hdb of=FreeDOS.iso |
| 44 |
dd: reading `/dev/hdb': Input/output error |

I don't like the Input/Output error message but it did create a file |
| 50 |
which gives the same info using isoinfo: |
| 51 |
|
| 52 |
~ # isoinfo -d -i FreeDOS.iso |

Now, how does one turn this ISO image back into a set of files and |
| 86 |
folders to be changed and later turned back into an ISO image? |

I see Joerg Schilling has responded. That's a famous name in this |
| 89 |
area. Off to read his pages! |
