BleepingComputer.com: test esata port

ok I have a mother board that supports esata and I just recently got an esata HDD because it doesn't have USB 3.0 and USB 3 is expensive. any ways I am having some trouble with the drive. when I connect it to the esata port on the mother board it has lots of problems. but when I remove the drive and connect directly inside my computer its fine. I want to know if there is a way to test the port so I know if I need to return the enclosure or cry because my motherboard went out of warranty about a month ago.

Yes I custom built the external HDD bought a enclosure and HDD to put in it so taking it out didn't void any warranties.

Probably the simplest way is to find another computer with eSATA and try the enclosure on it. If it works fine then the motherboard eSATA port would seem to have problems, and vice vesa. There's no easy way to test ports & interfaces other than by using them under varying configurations and by a process of elimination, work out where the problem lies.

I assume the eSATA port is integrated onto the motherboard? If it's on a riser with a cable, the problem could lie there.
