CD ROM problem

A CD ROM (Compact Disk Read-Only Memory) also known as firmware, stores and reads massive amounts of information on solid-state storage chip or a removable disk platter. Data on CD ROMs can only be read and not altered by the user, unlike the data on hard drives and diskettes.

CD ROMs do show common errors and compatibility issues with windows. Unless corrected, a faulty CD ROM can lead to a system crash. If your PC shows problems accessing the CD ROM drive and CD ROM is not detected, the first thing you would recheck are the physical connections of the drive. Make sure the drive has power. Then check that the data cable is connected properly. In spite of the reassessment, if the PC is still showing errors, then you may have to check with the issues related to software.

Problems seen in a SCSI CD-ROM drive:

• You would need to confirm that the working of the SCSI bus has been terminated, without causing system failure. The manufacturer provides a process terminator tool with an SCSI bus, to facilitate an emergency stop to the last connected SCSI device. The certification for the SCSI adapter offers more information about the termination process.
• You would need to authenticate the CD-ROM SCSI ID. The CD-ROM SCSI ID is automatically configured to SCSI ID of two or higher. The ID assigned to the SCSI components are unique, thus you need to ensure that the configuration file of the CD-ROM drive does not include a common SCSI ID that is assigned to another device.
• In the presence of printer components, set the SCSI ID of the SCSI controller to SCSI ID 7. Reaffirm that settings of the adapters are accurately setup to differ from the SCSI controller settings. Recheck the error messages and the error logs of the Microsoft Windows Event Viewer for regarding the working and debugging of the CD-ROM drive or SCSI controller.

Problems seen in an IDE CD-ROM drive:
A device driver for the IDE controller should be present on the PC. To ensure this, you would need to follow these steps:

• For an IDE channel, you can set the IDE controller to Master, Slave, or Cable Select (CS - rarely used). If there is a single device on the IDE channel, then the drive will be set to Master. After assigning an IDE status, it is necessary to read the product documentation of your CD-ROM drive to download the recommended device drivers.
• In the Device Manager, Ensure that the downloaded device driver matches the device driver that is auto-installed. If the device driver does not show similarity, then you can troubleshoot the manufacturer of the CD-ROM drive to obtain a device driver. Every manufacturer produces a driver programmed for the IDE controller that the CD-ROM drive is attached to.
• If the drivers are still unavailable, you can install the IDE controller driver included with Windows XP. These drivers are permanently compatible with IDE CD-ROM drives and are ATAPI compliant. Follow the instructions that appear on the screen to update the driver.
