I recently reformatted my DELL hard drive to run Vista, somehow the drivers for both original CD/DVD-roms have been erased and I do not have a floppy disc drive.

My question is, how do I install the drivers?

I have an

HL-DT-ST DVD+- RW GWA4164B ATA

and a


SONY DVD-ROM DDU1615 ATA

Also, if the device driver disc I have wont run where can I find these specific device drivers?
