    you should have 36 or 37 gigs because of the number games that manufacutures play with their advertisment.

    40 Gig hardrive = 40 * 1000 * 1000 * 1000 = 40 000 000 000
    where as
    40 GB = 40 * 1024 * 1024 * 1024 = 42949672960

    So a REAL 40 gig hdd would be advertised as a 43 gig

    As for the other 4 gb, i have noidea

    Sounds to me that your Bios is in need of an update. Ok try this reboot your computer then when prompted to hit the F2 key in there you can reconise your hard drive or attempt to change the size of the hard drive. If that doesnt solve it try you need a new bios chip or OS. also try useing win2000 that might do the trick it worked for me. I had NT and it didnt show my entire HD so I installed 2000 and that solved the problem.

    Thumbs up

    In the docs that came with the drive, or on a sticker on it,
    there should be the drive Geometry in cylinders, heads,and
    sectors. In a perfect world, your BIOS setting would
    accurately reflect this geometry. The PC BIOS has been
    improved/hacked several times to keep up with the size
    of hard drives, and drives report a "fictional" geometry
    to the BIOS. Check for bios settings like LBA, logical block addressing.
    Most recent BIOSs hav no trouble automatically recognizing big
    drives, but some may need upgrading.
    Is this drive a lot bigger than what you had before?
    How old is your BIOS?
    I came in to the world with nothing. I still have most of it.

    Remember also that drive sizes are often quoted Unformatted... I have two 20GB hard drives on my Windows 2000 system, and once formatted I have 18.5GB free space (because the file tables take up space on the disk!) So, i'm losing around 2 GB on a 20 GB, so that'd be around 4 on a 40GB, plus the other 4 from the post above:

    If my maths is correct, that's your missing 8 GB!!

    If you have exactly 32 gig, then I would wager you're using windows 98 or ME, which uses FAT32 partitions, which is limited to 32 gig.

    Check your disk management, and see if there is additional free space you can format.

    My supposedly 40 gig drives format with 37.2 gigs each under windows 2000, so there is some inherant loss due to what really should be considered false advertising. (40 billion bytes, not 40 gigabytes)

    I was under the impression that FAT32 was limited to 2TB (terabytes), not 32 GB... I could be wrong, of course, but my memory of such facts is usually quite reliable!?

    If, however, it is Windows 98 and ME themselves that are limited to 32GB, and not the FAT32 file system, then i don't understand how that can be the case, but I accept it since Windows 2000 has problems with 20GB NTFS partitions as the second drive (any drive other than IDE Primary Master), so I have to run my second 20GB HDD as an 8.2GB, NTFS Formatted, until I have sufficient time to download Windows 2000 Service Pack 2.

    Thumbs up Good thread

    This is a good thread... One of you might want to compile all these messages + add something of his own + tidy it and then post it into the Tutorials Forum as a "Hitchhiker's Guide to the Hard Disks".

    Heh, good idea!
    I would write a tutorial, but I only know about the software side of hard disks (partitioning, formatting, file systems etc) and the basics of the hardware (i.e. where to plug it in, what settings to set from master, slave, primary, secondary etc.) but I don't know all the details about hard drive geometry and cylinders, sectors and stuff.
