    Disk Defragmenting may take a long time especially if it hasnt been done after a long time.
    First make sure you clean up old files. press Win+W key at same time then type" free up" you should see an option "Free up disk space by deleting..." run this. Clean up old files and continue on with defragmenting. You said it takes a long time to analyze you can rest assure that it may also take a long time to defragment.

    defrag made to pass 2 at 95% and this took all of 12 hours before I shut the pc down for the nite

    Try IObit's Defrag tool, "Smart Defrag 2.7" if you wish. Works fine on my laptop, and is awesome when in conjunction with IObit Advanced System Care Pro. It's not a hell of a lot faster than Windows Defragmentation, but it's much, much, better.

    Reasons why it would take so long
    1) Slow HDD, which become even slower when fragmented.
    2) Not enough free space will slow it down significatly.
    3) A slow CPU won't help either, obviously there are a lot of 3rd party tools, personally i use Defraggler because I have more control of the defragmentation process.

    im trying defraggler after doing a complete disk cleanup
    I started defrag yesterday at 1pm and left it running and is still running
    it say it is fragmented 27% but only 1% is defragged
    my question is...........how long is a long time to defrag?
    I am running win8 64-bit and the newest i.e. edition.
    I was running win7 64bit and defrag would on get to pass2@95%
    I thot installing win8 would fix this problem but it seems hopeless!
    thanks for all and any input

    I set mine to defragment daily .
    Try disk cleanup.
    Try CCleaner.
    It won't hurt to leave it run overnight or all day.
    I have win 8 pro.

    isn't running the defrag for 24hours and only getting a 1% defragment saying that it could run for days and not complete?
    I ran it for 16hours and only got a 1% defrag
    should I instead call Microsoft support since I just downloaded win8 64bit pro?
    this is so confusing that it wont complete or even show better progress.

    You could just do a recovery install.?
    Complete full install.?
    Get thumb drive to keep things you want.!
    I used a 16 GB thumb drive to back up my entire computer for recovery.

    You could try Check Disk to check for errors.
