I took the defective drive back to the retailer. They allowed me to exchange for a new one. Thanks to glc's suggestion, they allowed me to use my credit card as deposite to take the defective drive home for cloning.
The old one is made in Malaysia. The new one is made in Thailand. I don't know whether the manufacturing location makes any difference.
I used Lifegaurd to close the software from the old drive to the new one. So far the new one runs very quiet. There is no clicking noise at all.
Thanks for all your suggestions.
