Unless the partitioning was done with and XP disc with SP1a already included, you can't use more than 137 GBytes in a single partition.

After you install SP1a or SP2 and enable large drive support, you can then make a partition for the rest of the drive, but if you want a single partition, you must start with an SP1a CD of XP.

I just received my new Dell Diminsion 8400

and Windows XP Home edition was installed with service pack 1a.

I seem to also have only 149 G hard drive? its supposed to be 160.

And when I go to  My computer it says I have 145G with 138G of free space.  Now I'd like to get that 11 or 15 G that I am missing because I will use my computer for editing video

Reported capacity of a hard drive is less than the size of the HD ordered on a Dell computer.

As the computer was purchased after 7.15.04, then the following post is applicable.

Thanks. The space appears to be right when converting from decimal to binary capacity

160g decimal =149.1g in binary
