OK, here is the just. I got a new HDD 250g WD. I previously had an 80g WD. I set everything up on the new HDD and it worked fine. Then, I got the bright idea to install my 80g HDD as a storage drive. Changed my jumpers, formated the drive, set the bios and boot config, everything according to plan . Now my computer does not recognize my dvd burner. When I open my computer it shows Main HDD as C: and storage drive as D: instead of E: with no optical drive showing. I checked my bios again and it is set to recognize both IDE slots not just primary or secondary. Each slot will work independently (meaning I can switch the cables around and it will work in either slot) but won't recognize both HDD and the optic drive. Why? HELP!
