Purchased this after getting an video card for my asus m11 and have had nothing but problems with it. The hd keeps loosing power, i had to hand pick which sata power adapter to use and then after a couple days of running my computer would slow down and start lagging. I would reboot and then i would not have a boot disk or my smart would fail, i pulled the video card out and the same thing would keep happening. I pulled the power supply out and put the stock supply back in and it worked fine again no problems with the hard drive and it worked perfectly for a week. Returned the first drive and received a new one, same problems as before, i had to try multiple sata power connectors before i found one to boot up on. It worked for a little while again then the computer started to have boot failures again.
