|First of all, are you sure about the current hard drive capacity. Specs I found indicate that computer shippped with a 40GB drive. The BIOS in your computer is not 48 bit LBA compliant. The chipset is an 845 series which does not support drives larger than 137GB.|
Look at the link below for help with tthat problem.
Your other option would be to install an add in PCI based controller card, which will allow you to use the drive.
Once you solve the 48 bit LBA compatibility issue you can clone the old drive to the new using a utility that most hard drive manufacturers have available for free.
You may also find a solution by installing the Intel Application Accelerator software. Link below.
