What version of Windows XP and Service Pack do you have?
Maybe not the latest service pack?
Drivers are software written by the hardware manufacturer to allow the hardware to work with different versions of the operating system.
If the manufacturer did not go to the trouble of writing drivers for older OS there is almost no chance you'll find them.
Use extreme caution looking at websites that offer drives that don't seem to be available on the laptop manufacturer's website. They may scam you to pay for drivers that might not work or load your system up with Malware/Virus/Trojan progams.
