i am running ats-h552d on a compaq presario i cannot use the dvdw because it has a code 19 which i now know it is in conflict with something else i cannot seem to get into my 2nd hd which is the recovery hd . i think now my best option would be to uninstal the ts-h552d and then reload it but as this is my only cd-rom how can i reload it and the drivers , help please this is very frustrating jon
