Thanks.

Today I have rebooted the hard drive many times, only
two times worked. maybe you are right, the usb to ide
controller has damaged.
But another question, sometimes I didn't connect the
USB hard drive to my laptop, just power on it, it did
the same thing, reset. after a reset, the hard drive
was unaccessible.

the hdd is definitely gone. Or the controller. Either way, you're better off
to return it to the shop, still in warranty, else you could try to break the
seal, take out the hdd, fit it into a desktop and see how it goes.
Even if damaged, perhaps that way you *might* be able to recover some data
- check for datarecovery pkgs, eg testdisk, mondo (iirc).

I believe you are right.
I have used the hard drive for BT download for two
years, this year use it to do weekly backup. but now
it retired
