Second Hard Disk making Computer Slow?

Second Hard Disk making Computer Slow?

The Problem: After installing a second hard disk in your computer as a slave it has started running slower.

Cause: This happens if the drive is in PIO mode or, if the cabling is incorrect.

Resolution:

Open Control Panel>System

1. Open Device Manager.

2. Double-click IDE ATA/ATAPI Controllers to display the list of controllers and channels.

3. Right-click the icon for the channel to which the device is connected, select Properties, and then click the Advanced Settings tab.

4. In the Current Transfer Mode drop-down box, select DMA if Available if the current setting is "PIO Only."

Also Check the cabling is correct (And a master drive should be on the end connector - any slave in the middle). Now in Device Manager, select the master controller - just above Primary Channel and Action; Uninstall. Then OK, reboot for PnP to try over.
