Go to Control Panel - System - Hardware - Device Manager
Look in IDE ATA/ATAPI disk drive controllers for the Primary Channel,
double click

Look on the Advanced page - I think it has got the drive into PIO mode.
Make sure that 'Use DMA if available' is checked. If it is, but the
device is in PIO, then something has caused the system to fall back on
PIO and stick there. Check the cabling is correct (And a master drive
should be on the end connector - any slave in the middle). Then in
Device Manager, select the master controller - just above Primary
Channel - and Action; Uninstall. Then OK, reboot for PnP to try over.
