If you are receiving a I/O device error with your CD-ROM drive, data cannot be read from the disc in the drive. This can be caused by a bad disc or when the transfer mode, used by the operating system, is not supported by the CD-ROM drive or has been changed. In order to resolve the problem you should first check the disc. You can then try changing the transfer mode of the IDE channel for the CD-ROM drive
Instructions Check the Disk
1. Restart the computer and wait for the operating system to load.
2. Open the CD-ROM drive and insert the disk. Wait and see if the disk will be read by the drive.
3. Take the disc out of the drive and see if it can be read in a different computer. Use the drive that is in a laptop, if you have one. This will verify whether or not there is a problem with the disc.
4. Insert a different disk into the drive on your computer and see if it can be accessed by the drive. If the disc is not being read correctly there may be a problem with the CD-ROM drive.
