hello folks :)

I have been given the task of recovering personal text files from a whole heap of 3.25" floppies which are written in CP/M 2.2 or IBM DOS.

To aid me in my task I am using AnaDisk, which handles both formats, though I can access the IBM ones via the edit command in DOS of course.

So far I think I am doing ok with the CP/M floppies, but I am concerned that I don't 'miss' anything, as the text I am recovering is the early writings of a man who died last year. Naturally his wife does not want to lose any of his work and has asked me to recover it and then copy it over to CDs' for her to keep.

I am not that familiar with all the ins and outs of Anadisk - and really I don't think I need to be, just how to find everything in text on the disk.

I was using the File command, which lists data by file names, and that works fine as far as it goes, but I have found that there are text portions on the disks that do not get listed as files, probably because they are just portions - I don't know - so I have resorted to using the 'Search' command as that appears to read each sector, if I press F10. I notice that paragraphs follow consecutively when I find text and then press F10 to access the next block, so I am reassured, but the thought occurs to me that there might be other parts of the disk I am not accessing because I am not pressing the right buttons or invoking the proper command.
David did a lot of writing even way back when he was using the Video Genie machine, and so far I have only found short pieces and letters. I feel there might be more. Can you help please? :)

I've not used anadisk other than for analyzing the structure of DOS diskettes to figure out what copy protection was used.

However, whenever I archive a diskette I always grab a full 'snapshot' of the diskette including the unallocated sectors. That is in addition to doing a file by file copy. That way, if there was a deleted file or a corrupted file allocation table I can detect the missing data and recover it later just by looking at raw sectors.

If these disks aren't copy protected the thing to do would be to get a file by file copy as you are doing, but also to get a snapshot. Teledisk should be able to snapshot an entire diskette for you, but you will need tools or at least a good hex editor to sniff through the snapshots with.

ah, Teledisk.. thank you kind person. I have a lot to learn about this business I can see. I will see if I can find this teledisk on the net :)
