The Second Life of old CD-drive.

Consider the most common problems and eliminating them. All failures of drives are divided into two categories: mechanical and electrical. Thus, the system determines the drive, but while reading it emits a rattle, the operating system periodically freezes. In this case, the drive tries to initialize the disk, but can not do it. Reasons may be several: controller failure, the lack of contact in the loop connecting the head and the controller, malfunction of the laser.

open the casing of the drive, turn and try to determine what is defective. Motor is working, the red dot of the laser is visible, the unit head is moving. In this case, most likely, failures occurred due to contamination of the laser. Cleanse the lens and the surrounding parts with a cotton-gauze moistened 30% alcohol.

If, after treatment, the laser reads the disc again, the problem in itself. In that case, you can by increasing current head, make laser laser work more intensively (ie read discs). Head on the block is a small resistor. By changing its position possible to increase the power supply to the head. However, we must remember that even a slight deviation to (a fraction of a millimeter) can significantly affect the laser and cause deterioration.
