My EIDE drive is using PIO mode instead of DMA in Windows. What could be wrong?
Problem: An EIDE drive capable of DMA is using PIO mode for data transfers in Windows. Cause: Windows may turn off DMA mode for a device after encountering certain errors during data transfer operations. Windows may downgrade the Ultra DMA transfer mode after receiving more than six CRC errors. Whenever possible, the operating system will step down one UDMA mode at a time (from UDMA mode 4 to UDMA mode 3, and so on). If the mini-IDE driver for the device does not support stepping down transfer modes, or if the device is running UDMA mode 0, Windows may step down to PIO mode after encountering six or more CRC errors. Resolution: Solution 1: Enable DMA. Please see &p_faqid=331&p_created=1025131316″ target=”_blank”>Answer ID 331 for instructions. Solution 2: Make sure that you have the latest drivers installed for your EIDE controller on the motherboard or your controller card if you are using one. Your motherboard manufacturer or controller card maker can assist you with installing the c
