I have a Dell Inspiron 530 purchased in 2007, and would like to purchase an HP (internal) 1270 I 24X SATA Multiformat DVD Writer (with Lightscribe) so my aspiring videographer teenage son can burn cool labels on the DVDs he is making for people with his new company.  I have read that my desktop is not SATA compatible - is there a cable I can purchase ( I notice several that are mentioned at the bottom of  the Amazon page for this product) that will make this work with my Dell? I don't really understand what SATA or ATA really means - but am trying to read and learn before I purchase. Any help would be appreciated!Below is the link for the DVD writer I'm looking at. Thanks!
