Urgent! ! ! I bought a new desktop computer, not a CD-ROM drive

vstal Enterprise, all is normal, I do not know what action after today's drive found the letter away, there is no problem of data lines, bright light can, I used to optimize the Masters, prawns help!

in the Control Panel, you have to add bios, so the problem is the drive, no optical drive is the hardware, then the problem is not the CD-ROM Data lines to forget the plug, if the software is not the problem, you can use to optimize the closure of the master of his letter.1.Data does not play well
2.Optimize the time to hide the drive letter
3.Data in the BIOS is banned!
