After upgrading to XP, the performance of the optical drive and the hard disk is degraded

. Q: I recently upgraded the operating system to Windows XP. Later, I found that the performance of the hard disk and the performance of the optical drive have dropped a lot. How can I solve this problem?
A: You can be in the system. On the desktop, use the mouse to select and enter “ Start → Control Panel → System & Rarr; Hardware & Rarr; Device Manager & Rarr; IDE ATA /ATAPI Controller & rdquo;, then view the current work of each hard disk through the primary and secondary IDE channels mode. For the hard disk, it should be in UDMA 4 or 5 state, and the optical drive should also be in UDMA 2 or 4 state. If it is displayed as PIO4, you need to set the transfer mode from PIO Only to DMA if available, and then restart the operating system.
