Hi there i have a Samsung HD103UJ which came out of a Lacie external HDD which was working. I removed it because i wanted to put it inside my case. Now the problem, when i try and install it via sata cable to any of the additional sata ports on my mother board it wont let my PC turn on fan moves for a split second then i have to remove power cable and remove Samsung HDD to power up my pc again. I am not a complete Noob as i have built many pc's and upgrades. But this has me stumped. Please let me know any further info you need. It is a Gigabyte Mainboard.
