"If" you bought the wrong drive, only if, it wouldn't effect you for a long time, only if DVD+R dissapears, and that won't be for a long time if it ever happens. By then we'll all be buying new drives anyway for one reason or another. I mean if you kept that drive for 2 years you'll want to upgrade to something else by then anyway, just like the rest of us. So don't freak out about it
