Segate External Hard Drive How to test it

[zillah]

I have got an external segate hard drive that connected to my laptop through USB cable, I doubt that there is a problem, then I decided to test it by using : Segate seatool utility (windows version not dos version) that I have downloaded from segate site.

I can see the external hard drive :

But the test option is unavailable!!!!

Is there any other utility that can test such a USB connected HD ?

I knew that we can connect faulty hard disk directly to the mother and then run the test from CD or floppy, but this is not feasible in my case

Computer>Right click on the drive and run check disk. Basically the same thing as those tools. It will test for bad sectors and all that.
