Users questions: My computer is a Panasonic drive 8285DVD-ROM, in a read pirated VCD disc, due to read a long time, I have not read the disks to complete its case on the order of the normal shut down the computer shut. After reboot, found the letter of the DVD drive into a CD, now drive Can only read CD, VCD, while the DVD can not read, and I do not know why, there is a labor of you master. Drive is the Panasonic 8582DVD-ROM, give me the latest driver? (Installed in WINXP), I was here Xianxie.
Experts answer: seems light Flooding a problem. CD-ROM drive failure should be how to decide when a problem occurs, the general performance of the drive's light constantly flashing, can not read the disk, or read the disk performance degradation; drive letter disappeared. CD-ROM drive can read the disks, or when the blue screen of death "can not access CD-ROM device not ready" and other boxes and so on. 1, CD-ROM with Improper access drive installed, boot self-test, if they can not detect the drive, they should carefully check the drive cable connection is correct, reliable, drives the power supply line is properly connected. If the self-test to drive the screen when this one stops, they have to look at drive (master, from) the jumper is correct. Reminder: drive as far as possible Do not drive with the same data line. 2, the internal drive stuck contact problem can not pop up if the situation is probably the drive contact between the internal parts problems, you can try the following method to solve: the drive from the chassis and use the Phillips screwdriver remove the open, by emergency pop-up hole bomb The drive tray, so you can drive the removal of the cover and the front cover. Remove the cover of the movement will see the drive in the tray on the left or right side there will be an end of the tray motor attached belt. You can check the belt is clean, whether there is dislocation, but also can be connected to this belt and the end of the motor Oil. Another drive tray will be a row of teeth on both sides, the sawtooth is to control the tray pop-up and retracted. Please give this sawtooth oil and see if it is not the fault dislocation of the class. If, on the oil please wipe the excess oil, and then re-installed the drive, and finally try boot. Reminder: However, given the Kind of service more professional, it is recommended you find the best repair professionals. 3, CMOS settings problem if a Power On Self Test to drive when it stops or freezes, then there may be the CMOS settings in the drive mode of operation due to incorrect settings. Generally, as long as the IDE interface, all used Set to "AUTO", you can correctly identify the drive mode of the. For some early board or individual phenomena need to be set. 4, issue-driven Windows systems, when the motherboard drive misoperation caused by a virus or lost, will not be IDE controller system is Correct identification, thereby causing drive failure, then we just re-install the motherboard drivers on it. Also, there when a drive to repeat or multiple installation drive misoperation when Windows will recognize more than drive, it will blue screen when Windows starts phenomenon. We only have access to W indows safe mode (click on "My Computer Properties CD-ROM") to delete the extra drive to solve. 5, CD-ROM drive does not support DMA may not support the early DMA, the DMA interface, you can drive close to avoid such phenomena are not compatible. After setup is complete, press the "do Set "button, restart your computer. DMA interface to drive is not compatible with the motherboard, they should turn off DMA. If you really want to take advantage of the performance caused by drive DMA, then the proposed upgrading the motherboard BIOS or drive firmware (Firmware ). In addition, the drive to use for a long time, will the Now read the disk instability, we can try to turn off DMA, to reduce performance, increase stability. 6, virtual drive conflict, while we install the drive, usually put on a virtual drive to use. But after installing virtual drives, and sometimes found that the physical drive "lost", which is due to hardware Configuration file settings are too few available drive letter. Solution: Use Windows comes with Notepad program to open the root directory of C under the "Config.sys" paper, adding "LASTDRIVE = Z", save the exit, reboot can solve the problem. The situation in the installation of dual-drive Install a low version of the "virtual CDs", the individual circumstances will be manifested as one or two physical drives, "Lost!" Recommendation: another high version or other virtual drive program. 7, the laser caused exclude dust caused by the aging of the reason can not read the disk if the drive is likely to be "laser" is aging, and this Will have to adjust when the laser in the vicinity of the potential of optical modulators, increase the resistance to change the current strength of the power to launch tube to increase and improve the brightness of laser to improve the drive's read the disk capacity. Reminder: We used a small screwdriver to adjust clockwise (clockwise to increase power, reduce the power of counter-clockwise) to 5 degrees to adjust for the step, try changing sides until the edges are satisfied. Remember not adjust too, or else the laser power may be too big to burn situation.
