I have two DVD drives (A & B) For some reason, my computer won't recognize a secondary disk Drive when linked with the IDE cable. If the cable is plugged into just one of the drives (A or B), the computer will recognize it as the primary drive. If I have them both plugged in (A-B or B-A) it won't recognize the secondary drive, regardless of what drive it is. Since they both work by themselves, do you think the problem is in the cable, bios, or firmware? Any help would be appreciated. Thanks.
