....but I'm having problems with the drive. Keep in mind I'm relatively new at this so please bear with me. Ok...this is what's happening...my 2 year old Compaq Presario came with a CD-ROM and a CD-RW. I've decided it's time to upgrade it and so far, I've added a DVD-ROM. Two days ago I bought the BUSLink 48x12x48x CD-RW drive. (Under my device manager it shows up as Lite On). Anyway, after I installed it I tried it out by burning a CD but the E: drive (original CD-ROM) won't read any disks. If I put back the old CD-RW, everything works fine. The new drive didn't come with any drivers. The ribbons are properly connected and they are jumpered as follows: E: CD-ROM Master F: CD-RW Cable Select G: DVD-ROM Slave What could be the problem here? I greatly appreciate any input...I'm ready to put this thing back together!!
