i need help! today i have decided to buy a dvd rom drive i've been using a cd rom drive for the past 2years.. i've bought a Sony DVD ROM DRIVE model no. crx320ee. so i've removed my old cd rom drive and replace it w/ my new dvd rom drive, i've connected the cable and power chords properly but after i turned my pc on during post "DISK BOOT FAILURE INSERT SYSTEM DISK AND PRESS ENTER" i did double check my connection and everything seems fine.. then i got frustrated and i installed again my old cd rom drive and my pc booted w/ no problem. what seems to be the problem w/ the dvd rom drive i bought? or is it something to do w/ my drivers? please help me.. Thank you in Advance!
