The tools within the Computer Management console include Event Viewer, Performance Logs and Alerts, Device Manager, Removable Storage, Disk Defragmenter, Disk Management, Services, WMI Control, and Indexing Service.A hardware device may exhibit errors because of its separate adapter's configuration, device driver, or general failure. For example, a SCSI device may exhibit errors when the SCSI adapter is not terminated or has an incompatible driver.Table 8 describes common problems encountered when installing or using CD/DVD drives, and the appropriate solutions.
