    Data Recovery from Floppy

    Can someone describe to me the process by which data is recovered from a floppy? If not a description, a link to a page describing it will do.

    Google searches only bring up companies that perform data recovery for you, which I could care less for

    Yo Frog! :)

    Try...

    http://www.softlookup.com/category/cat437.html

    That shows a list of data recovery programs you can download for free. Recover98 should retrieve all your files for you.

    Regards,

    Paul.

    P.S That link was pulled from Google!

    Yo Paul :)

    I'm hoping that was a really subtle joke, since I was looking for the process of data recovery.

    It is probably lots of way to do it....I know that good old Norton used 80paterns for 7years ago, and there is probably more now. So whitch one do you want, and the algorithm or the physics???

    Well its the same as HDD recovery I believe.
    They open the device in a clean room and go sector by sector recovering data...

    when files are deleted, the cluster map of where the data lies is zeroed out and the slot in the file allocation table is marked as ready for reuse. (only the first character of the file name in the FAT is changed)

    from the FAT you can see most of the original files name, its starting cluster, and its filesize

    the actual data clusters holding the files data are not touched.

    if the disk was relativly clean and there was not alot of deletes
    or additions made since you got the disk, it is quite possible that all of the original data is on disk still and can be recovered.

    depending on these factors you may find all of the clusters to be sequential or scattered (fragmented file)

    you can reassemble and extract the file cluster by cluster if you have to.

    here is a paper and free tool I developed when I was tryign to figure out how all of this worked
