Missing hard disk capacity

  brewersfan 08:56 14 Apr 08


I recently bought a new Western Digital 160Gb HDD (model WD160AABB). When I came to partition and format it before installing XP Pro, the maximum partition size showed at approx 127Gb. I know that there are two methods of defining hard disk capacity, i.e. 1Gb can either equal 1024Mb or 1000Mb, but 33Gb seems rather a lot to go missing. What do you guys think?

XP pro, with what service pack, sp2 will see the full size of your hard drive.

I have XP with service pack 2 on there now, and it shows 127Gb with 121Gb free.

Thanks for your help and suggestions on this everyone.

It looks like I'll have to reformat using the WD tool but that won't be until the weekend at the earliest.

I'll come back afterwards and report success or failure as appropriate. Until then I'll leave the thread unresolved.
