    Just a quick question this time: does defragging my computer's hard drive make it more or less likely that I can recover deleted stuff from it? That is, defragging it after stuff has been deleted.

    Thanks :)

    Less likely, as there is every chance that data will be written, during the defrag process, to the sector where the file was before it was deleted.
    When a file is deleted in the first instance it is deleted only from the Master File table - which you may consider to be the index

    However as I said
    When a file is deleted, the data remains on your computer's hard drive, albeit inaccessible by normal means, until it is overwritten. When you run a defrag program, your computer rearranges the bits of data on your hard drive so that they are better organized. In doing so, it overwrites files.

    If you run a defrag after data is deleted accidentally, chances are good that your system has overwritten the sector of the hard drive that contained the deleted data, making it harder to get it back.

    Remember that Windows 10 has a built is defrag that works when the system is not busy.
    No third party defrag program should be used, as none of them are using the format that MS has designed to be used.
