    no, the worst it does is put a little wear on your hard drive.

    my format took much longer then normal and had a few failures in the log, is there a way to see if everything went ok?
    i don't notice any problems...

    you dont need to worry about your hard drive every time you write/delete your files.

    • On a mechanical HDD you can write forever without anything bad happening.
    • On a SSD you would have to write (I beleive) about 30GB a day for 5 years to kill a drive.

    Formatting only writes about 100MB (which less than browsing the web for for 5 min).

    Reinstalling OS X writes about 4-9GB depending on the version (about the size of a HD movie from iTunes).

    EDIT: 30GB a day is for a 80GB SSD. Larger capacities will have higher endurance.
