DELL VOSTRO 330 HELP Needed

Hi I have Dell Vostro 330. MY mother board cannot detect any drive on sata port 0 and 1. I cannot find new motherboard as your company does not make one. I was thinking if I could buy USB to Sata connector and connects external hard drive as an internal one to make the vostro running. Is there any other solutions expect changing the motherboard.
