    Default Large chunk of mysterious used space after format

    I formated a 140 GB HDD and after the format there's roughly 21 GB of used space. I have no clue whatsover this mysterious used space could be. I did this format after the HDD's MFT table was corrupt, which I posted about before.
    I used Partition Magic, did another format, resized the clusters to 512kb, made it a primary partion instead of logical. Not that I think all this would do any good.
    But that used space is still there. I this something that's like permanently on the disk? that would really suck coz, 20 gigs, is a lot of lost space.
    Help appreciated.

    edit, just did a properties check with PM and that 21 gigs falls under the bad category, not the used. this sounds like bad f'ing news.
    time to hammer on my pc??

    Now you know why the MFT table got screwed.

    That is one HDD that should go in the bin.

    Would it help if I "Zero-Fill" the HDD. I hope you know what that is. If it doesn't get that space back, should it be destined for the bin? can I still use the other 120 Gig? or does one MFT failure indicate it'll surely happen again?

    and no, i still don't know what screwed the MFT table up in the first place. I was just doing things as normal, then bang. If you know what the reason was or might've been, then plz tell me.

    Most of my Hard drives have a few GB missing when there is nothing on them, the smaller ones have about 2GB missing but my 250GB HDD can only hold 231GB! Dunno why this is, but I think its normal... or not, I dunno!

    A 250 GB HDD will show as about 232 GB under Windows
    The drive makers use base 10 (decimal) but Windows reports as Binary.
    250/1.024/1.024/1.024 = 232.8 GB

    If I had a drive that had that much in the way of bad sectors I would not trust it with any data. Its usually a creeping disease. Zero filling has no relevance as I see it.

    Cool Re: Large chunk of mysterious used space after format

    I agree with "godfather",once you start getting bad sectors it will only get worse.

    I'd back up all data and files you wish to keep, and buy a new one, and/or buy a new HD, install as a slave and using a copy program like "Nortons Ghost" clone everything over to your new drive, then set new drive as Master.

    However its not all bad, after you install the new HD it would be a good time to see what the insides of a HD looks like.

    So are you saying my 250GB hard drive that can only hold 231GB is full of bad sectors and will probably get worse????
