IDE Controller and can I uninstall?

I share my WIN XP with my kids and I opened my Hardware manager to find that their appears a disk drive that shows Samsung SV4002H and I am sure that I never saw that there before. Nothing has been added to my machine, however this also appears in the bios as my “IDE”. One of my kids said they “may” have downloaded “firmware” update, because they thought they were supposed to when they found it on some website. ERRR. Please can someone help me?
