USB cable and strange behavior with disk in enclosure...

I think one of disks in USB disk enclosure I had just got broken because of faulty, or something, USB cable. Now, I don't know how it is possible, nor what exactly happened, but I have a strong feeling that I'm right. Namely, what happened is that when I plugged the cable into the enclosure I heard strange sounds, like the heads are trying to move but are being retracted back to initial position; a series of clicks, about a second apart. That happened almost every time I used that cable. At first, I thought that the problem is that the USB ports are USB3.0 while enclosure is USB2.0 and something is wrong with currents or who know what. But googling didn't turned anything about that. Then, I tried another one and disk worked normally. WTF?!

Well, I found out that when power source isn't strong enough the symptoms are clicking that's heard in the disk. In that case you should unplug the disk as soon as possible. Also, you probably received additional cable with a caddy that will allow you to solve this problem. What happened in my case, probably, is that the cable is somehow faulty and probably decreased current so that disk didn't have enough power.
