Q: I recently upgraded the operating system to Windows XP, and then 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 You can use the mouse to select Enter “Start →Control Panel & Rarr; System & Rarr; Hardware & Rarr; Device Manager & Rarr; IDE ATA/ATAPI Controller & rdquo; on the system desktop, and then view each hard disk through the primary and secondary IDE channels Current working 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.
