New hard drive 160 GB ATA can't be par...

I recently buy a new HD ATA 160 GB then i started to insert my XP cd bootable to install the OS. So far, this HD can be detected. Then first i want to partitioned this HD, with type "C" as it promted to create new partition and it displayed the HD capacity : 152625 MB. I started to insert new numbers, ex: 35840 then press enter button. But after that in the next layer the new partition doesn't exist, it still displayed 152625 unpartitioned drive. I tried to install the OS so i pressed the enter button to the unpartitioned drive but it still ca't be installed. Maybe someone have the solution to this problem, i need your help. Thank you so much.
