Troubleshoot CD/DVD Rom



Dear Readers, At this time we will discuss thoroughly about the CD/DVD Rom, it's problems, how to treat a CD/DVD Rom etc. Hopefully this discussion will be helpful.

CD/DVD Rom does not read
solution:
  • Clean the head of CD/DVD Rom
    I Often get the question, why CD/DVD Rom can not read? when I recently bought 2-3 months ago, the first question I ask is whether it's head ever cleaned??. Head on CD/DVD Rom has the same function as the eyes, if the head/eyes dirty then our vision will dim or obscure, as well as head CD/DVD Rom, a laser beam generated by the head can be blocked by dust which resulted in reading the CD/DVD so it is not smooth. The solution, buy a CD/DVD Rom cleaner, usually equipped with alcohol.
  • Clean the CD/DVD
    I Often find there is fat or hand printing on the surface of the CD/DVD, this will make CD/DVD Rom be broken, because the head will be forced to read the CD/DVD, hence before the CD/DVD is inserted into the drive, make sure it's clean from dust, fat or other materials. To clean fat or hand printing we can use cd cleaners that are sold in many computer stores.
CD/DVD Rom can not be ejected
Ever have a CD/DVD stuck and can not be removed from the drive??, if so grab a paper clip, then while pressing the eject button on CD, press into a small hole located on the CD/DVD rom.

CD/DVD Rom is not detected
The common problems, to fix it, first check whether the indicator light on the CD/DVD Rom is lit, if it does not, it mean that the matter is power, try to replace the power that is connected to a CD/DVD Rom with another power cable, of course, we have to open the computer casing first. If it's lit but CD/DVD Rom still not detected, the next step is to check the IDE cable, it's the flexi size cable that attach the power cable in addition, try to replace it with another IDE cable, usually by using two steps of this, CD/DVD Rom will be detected again, if it's not then it can be hardware damage and we may have to buy a new one.

  3. Check the BIOS, whether the first boot is from the Hard Drive that has a boot sector or Windows is installed

If all that solutions don't work, try the following:
  1. Insert the Windows CD into the CD/DVD Drive.
  2. Restart your PC/Laptop and set the first boot from CD/DVD Drive.
  3. Press enter on the message "press anykey to boot from CD".
  4. After entering the Setup Menu, press "R" to enter the repair command line.
  5. Next will be asked, where the windows system lies??, choice of numbers appears, select the number that contained the windows system, for example: if on drive C then choose number 1
  6. Next will be asked the administrator password, type it and enter.
  7. Copy the files NTLDR & NTDETECT.com into the system. For example if CD/DVD drive is drive 'D', then the command is
    Copy d:\i386\ntldr c:\
    Copy d:\i386\ntdetect.com c:\
