    Ok, so I have a new external drive, 1TB to be exact. There is no way this thing is full. I mean, I have roughly 40 gigs of itunes content, 30 gigs of photos, 100 gigs of video and 20 gigs more of misc. So I am well under 1000 gigs.

    I have searched and tried some things like connecting the drive and making sure to empty the trash. No luck I reset the PRAM hoping it would do something. No luck.

    I have no clue what do do from here. I guess the only thing I can do is maybe try to fit all of this stuff on multiple drives I have and then erase it and start over. Ugh!

    Any ideas are much appreciated. Thanks guys.

    What do Disk Utility and Activity Monitor say about it?
    How _exactly_ does your hard drive tell you that it is full?

    Take a look in Disk Utility. Select the drive, and click the Partition tab. Does/do the partition(s) fill the drive completely or is there grey space?

    Curses, beat me to it!

    and presumably you have the drive formatted for HFS? If it was formatted for Windows FAT, that would explain a lot.

    Just posted a thread about this issue and a member told me to use Omni Disk Sweeper. Search it up, it works wonders.

    fat allocation can waste a lot of space. A file that only takes up 20K can use up an awful lot depending on the allocation units.

    Well, I would imagine that it was formatted right. I would hope that it is not formatted in FAT. It is a external drive from macsales/owc.

    When I go to diskutility, the pie chart is showing full. I now have around of 100gigs free after deleting some stuff. There still is no way that I have 900gigs of stuff. I came from a 320gig hd.

    I will have to check more about the drive when I get back home.

    I will definately look into omni disk sweeper.

    And, just to be sure, you have emptied the trash?

    Sorry if I wasn't to clear but I have tried the trash trick. It didn't work for me. I only had a few items in there. I was expecting thousands of files to appear when I connected it but no luck.

    Ok guys, here are the results.

    I checked out omnisweeper like JoMac suggested and that pointed me in the right direction.

    All of my previous estimates of sizes on iTunes, photos, and such were pretty close. What was way, way, way off was my time machine backup!!! Holy crap! 667.2GB! Insane! Uh, that explains alott.

    So, without going on further, what's the best way to prevent time machine from doing this? At this point I feel like I wouild almost rather back up my important stuff, music/photos/docs/etc, and make a clone of my drive then mess with time machine. I mean holy crap!

    Should I just partition a part of the drive specifically for time machine so it will "limit" itself and delete old backups automatically?

    Guys, thanks for the help. I'm always amazed what happens when questions are asked here!:D

    Parititoning the hard drive to limit time machine backups is a good idea; it's basically the only way to really share time machine on a physical drive. I have a firewire drive with time machine and other stuff and have a time machine partition plus a data partition, which is not backed up.

    This is really the best way. Choose how much you want to allocate for TM, like maybe 250GB, then create a partition that size. From there, you might want to go into the TM prefs and exclude some folders. Obviously, you don't want TM backing up your files on the external drive (but by default, I don't think it does). You might exclude applications and system files, though, and just back up your Users folder.
