I have bought my 500 GB hard drive.
It was woking fine for 4 months.
Then once, i connected the hard disk to my computer, it detected but after 10 seconds, it was not detecting.
I tried many times again but it wasn't detecting.
I bought a data cable too for the hard disk but still it wasn't detecting.
Please help.
I would be very thankful.
 
Solution
If it's a portable hard drive which relies on sufficient power from the USB port instead of power from mains supply, you may have to buy a mains-powered USB hub and plug your portable drive into that.
