I've seen brand new drives on this model fail within an hour of being put into service. The only way to know for sure is have it tested by a service shop or try it in another pc.
One test you can do yourself is to change the boot order in BIOS setup to "optical drive" as the "first boot drive", then see if it will boot with a Windows XP install disk inserted in the drive. When you see the message "press any key to boot from optical drive" (on the monitor screen), do so. If the drive fails to boot up, then you have a bad drive. If it does boot, then you have problems elsewhere. Let us know how it go with the test.
