Slowness during read-write hard disk

If you notice that your computer has become very slow when writing or reading your hard drive the problem may be due to the transfer mode set to PIO instead of DMA.
In fact, the Windows operating systems if they experience errors during the data transfer start to change this mode by lowering the speed up to PIO.
To test this method should access the "Control Panel - Device Manager" and go over ownership of the hard disk controller, where the View tab you will find the transfer mode.
If set to PIO can groped to enter the DMA uninstalling the controller driver and restarting the system. Once Windows starts automatically install the missing driver, so I ask for a new restart.
To examine whether the mode is returned to DMA.
But we must take account of the above, if the operating system has lowered the transfer mode means that there are errors then make regular backups of important data and do not trust blindly on your hard disk.
