    I do a lot of work on older machines.

    I've found that if I need to add a larger 2nd drive to a machine that
    has a 137 Gig Bios limit...
    all I need to do is *disable* that drive in the bios and let the
    operating system detect the drive.

    I've been doing that for years and have never had the slightest problem.


    Well, now I've worked on a machine where I am simply replacing two
    smaller drives with one larger one the ...and I used a 160gig
    drive...but the bios only detected it as 137gigs (and no, there is no
    bios update )

    I went to install XP-sp3 and the installer recognized the entire drive.

    XP installed and works fine


    I'll be darned

    I work on older machines sometimes, I'll definitely remember this, thanks!

    Many drives can be jumpered to run at full or reduced capacity. It is also
    possible that your BIOS is too old to recognise large disks.

    freaky. i guess it's critical that the 1st drive boots the pc, and its size is within bios's
    gb limit.

    i wonder if there will be occasional "burps". maybe for some functions, xp will look at
    the bios.

    oops my recent reply, i didn't digest the flow of your post well...
    this is even freakier.
    and yuo haven't partitioned the 160gb?

    I recall reading somewhere that the BIOS only matters for the boot process.
    Once Windows XP takes over, it will work out by itself what disk you have.

    Well back in the old days...

    IE : when I used a P-1...
    when I put in a 20 gig drive...
    the bios saw it as six gigs and that was that. Fdisk also saw it as 6
    gigs( At least as far as win98 could handle it.)
    However I do recall that if I partitioned and formatted the drive on a
    machine whose bios could handle a (huge) 20 gig drive,
    then I could put it back in the older machine and load win98 on it and all
    was ok.

    Norton utilites saw the drive as mis-configured...
    but no windows utilites had any problems.

    So with XP_sp3 at least...
    I think as long as the bios can detect a drive at all...
    the exact configuration (as seen by the bios) is apparantly not that
    important.

    If you do a lot of work on older machines then you should have
    known that all HD manufacturers have a tool to enable larger
    disks.

    One such example is here:

    Why take risks with customers data when you can blame larger
    companies for c0ck-ups!

    XP_sp3 has no problems with drives larger than 137G

    I was referring to the bios and it's lack of support for drives of that
    size.

    Until Windows starts running, disk access is performed via the bios,
    so as long as the bios does not have to access past the 137GB point on
    the drive during the boot process, there won't be any problem. Since
    the NTFS backup MFT is at the midpoint of the partition, a 250GB drive
    with a single partition will work. A 300GB drive won't work.
