On my old computer w/c is the Samsung MA10. I have a problem about the CD-ROM's -Because there are 2 CD-ROM's Installled but the problem is that when i checked it at the CMOS, there is no CD-ROM installed. So i checked the Power Cables, IDE Cables, Resetting the CMOS Data and arrange the jumpers. But nothing has changed. Then I tried to remove one of the CD-ROM's but luckily one worked. But when i put the other one back, all went gone (It means that when I checked it again, There are no CD-ROM's Installed.) What Could Possibly the Problem? and one question; If the clear the ESCD Data what would possibly go wrong? Thanks
