Overclock your hard drive!!!

Heres a much easier hack that I realized quite a few years ago that really does work!

REQUIREMENTS:

• Hard drive with molex power connection.
• PSU with more than 1 strand that has molex plugs on it.
• Wire strippers, soldering iron if you're fancy, electrical tape if you're not.

STEPS:

• Take the strand of connectors from your PSU, and decide which one will be the donator for this overclocking adventure.
• Cut the yellow and orange cables, then twist them together.
• Find the power connector you've chosen as the overclocking connector, and release the orange cable from the connector. Now use your preferred method to bind them together, then place it back together.
• Plug in a drive and feel the speed!

Congratulations! You've just overclocked your hard drive!

I would suggest you to plug in hard drive then check in disk management you can see the drive or not.

Follow the steps to check Drive in Disk Management.

• 
  Go to the Control Panel then click on the
  Administrative Tools. .
  
• 
  Under the Administrative Tool Click on Computer Management.

Also check in BIOS whether External Hard Drive is listed or not.

For help with the BIOS settings, refer to the computer manual or contact the manufacturer.
