While Windows Vista is indeed an evolution compared to its predecessor, Windows XP, there is a cocktail of minor glitches with the new operating system that have contributed actively to the product's rough ride so far on the market. When, even before Vista hit the shelves at the end of January 2007, Jim Allchin, the former Co-President of the Platforms & Services Division described it as neither foolproof nor perfect, he was right on the money. With Vista, a range of issues also came to the table including hardware and software incompatibilities, reliability and stability problems and poor performance under specific scenarios.
And just such a scenario involves the integration of certain DVD-R/RW drives with the latest operating system from Microsoft. "On a Windows Vista-based computer, you finish recording an optical disc, such as a CD-R, a CD-RW, a DVD-R, or a DVD-RW disc. To record the optical disc, you use the DVD-R/RW drive, and you select the mastered disc format. Then, you notice that the read speed of the drive is much slower than the expected speed. This slow read speed causes the Windows Vista operating system to take more time to copy files from the drive," reads the fragment dealing with the symptoms of DVD-R/RW drives speed problems on Vista, from Knowledge Base article 942869.
Microsoft advises users that experience this problem to simply reboot Vista in order to be able to use the DVD-R/RW drive at optimal speed. In the case of external DVD drives, only the device has to be restarted. Both actions are designed to reset the DVD drive to its default speed. Alternatively, there is also a hotfix available but end users have to contact Microsoft directly in order to access it. "When the system is writing the disc, the drive uses a slow speed. However, some drives do not automatically set the drive speed back to the default speed after the system finishes writing the disc, and the system ejects the disc. Therefore, poor performance occurs when the system reads the disc again", Microsoft added.
