Windows 7: Sata Hdd / cable / motherboard sata / problem?

Relatively new hdd disappears after some time.
(1Tb WD black sata3 jumpered to sata2)
All cables are sata click.
The drive is used for storage and is accessed only few times a month.
So is any way to test somehow what is the problem
hdd, cable or mb sata connector (GA-EP43-DS3L).
It's all start with annoying red hdd activity light lighting all the time when a drive disappears.
After a reboot all is back to normal for some time.
Tested a drive with hd tune pro and it seems ok.

-up normal
-down 1Tb missing

a few things to try first.

-use a different sata cable
-use a different power cable
-try the drive in a different sata port on the motherboard

my first thought was a motherboard fault, which it may well be but try the above first, if nothing else you can eliminate three things as possible faults in the mean time.
