hard disc not fully recognised

Hi Jay,

Start/run diskmgmt.msc and look at the drive, is it split into more than one
partition? If your system came preinstalled, part of the drive may be used
as a recovery partition that houses an image of your original installation.

I have installes a 160gb hd and win xp only shows 131gb??


There is an important 'break point' in the hardware interfaces for IDE
disks at 128 GB (binary - 137 decimal billion; 131 thousands of binary
style MB) Up to there 28 bits as originally defined for the 'LBA'
access method was sufficient to give a unique nu,ber for each sector.
Go above that and you need more - so 48 bit LBA has been brought in.
This needs support in the drive itself; in the operating system (which
means SP1 for XP) *and* on the motherboard. You probably do not have
the motherboard support. A BIOS update *may* be able to fix it;
otherwise you will need to get a plug in controller card for 48bit LBA
devices - any UDMA 133 speed one will do it.
