    So i used the built in disk management in windows vista to shrink the hard drive to create unallocated space to create a new partition to store data on.

    so i shrank the C: drive which it did but it doesn't longer show the unallocated space? i'm also unable to extend the C: drive back as its greyed out?

    i then decided i'd just re install vista but again it doesn't show the unallocated space, nor does it allow me to extend the C: partition? back.

    any ideas.

    The laptop is an acer one, i have no rescue disc. whilst the restore partition is intact i am unable to replace the acer MBR (trust me i have tried) to boot via Alt+f10 and restore.

    so

    i shrank a 139GB hard drive by 57GB to be used as data hard drive

    after the shrink it shows the 9GB restore partition, the 79GB boot partition + a small 3GB partition that only shows "help" when right clicked on.

    so there is the 57GB missing!!!!

    it DOES NOT SHOW! not as unallocated space, nor as a hard drive/partition.

    if i use command prompt and diskpart which shows it as 139GB but will not extend size by any amount and gives the error "there is not enough usable free space on specified disk(s) to extend the volume"

    even when i try and do a fresh install it only shows the 79GB and the 9GB partitions NOT the shrunk 57GB space.

    Ok I have solved this.

    I slipstreamed an xp disc using nlite into a firtual floppy so xp recognised the sata drive.

    I then ran the xp install which saw the dead space and allowed me to format it.

    Once booted into vista it then saw the partition again.
