For one, I abhor Packard Bell, and the lack of support for it's users, of older computers.
If you don't support your computers, I say do not buy one from them.
(Oh, excuse me. For $$$$$$ they will)
Can't even find the specifications on the internet, (I do not own one), and Peckard Bell Support is of no help.
So let's do it another way.
What kind of cables connect to the Harddrive?
This will tell us if it is an IDE unit, or a SATA unit.
An IDE, (Also known as PATA), harddrive uses a flat ribbon cable, for it's data cable,http://en.wikipedia.org/wiki/Parallel_ATA
Click on the photo all the way to the upper right. Shows a blue connector on a grayish flat cable.
The power cable for an IDE (PATA) harddrive, is a 4-pin standard Peripheral power cable. Shown here,http://www.playtool.com/pages/psuconnectors/connectors.html#peripheral
Note the harddrive shown in the photos, is an IDE harddrive.
If it is a SATA unit, it will use a SATA power cable.
Has 15 contact pins in the connector.http://www.playtool.com/pages/psuconnectors/connectors.html#sata
The SATA power cable has an L connection on the inside, to match the L connection on the back of the harddrive.
Same with a SATA data cable, only it is shorter in width, and has 7 contact pins,http://en.wikipedia.org/wiki/File:SATA_ports.jpg
Also look at the label of the harddrive, and state what you see.
Is it a Seagate harddrive? What is the size? 250GB?
Once we find this info out, I can recommend harddrives.
Be aware that the Windows operating system was on that harddrive.
If you install a new harddrive, it won't have Windows on it.
You will need to obtain a genuine copy of Windows, and install it.
