I bought a wd5000aakx hard drive. It is one of that models that came with Advanced Format Drive.
I did a clean install of Windows 7. Everything was working fine, and loading fast. But one time, after comming back from the suspended mode, after typing the password, it crashed, and I needed to press the reset button.
Another time, after a long time of inactivity time the motinor was turnned off. I pressed a key to turn it on again, and after this the problems started. Everything was completly slow.
I needed to press reset again...
After this Windows is taking a lot of minutes to show the backgroudn with the cursor. I did't have patiance yet to wait for the menus to be loaded (I'm not sure if it will really load).
To increase the problem, I tried to boot from the windows DVD again... And it is completly slow too. I felt asleep waiting for the installation program to start. When I clicked install, everything was completly slow.
So, I think this maybe a hardware problem.
Ubuntu is loading fast from a pendrive.
My HD cable was on the "orange" sata port. (I think its sata II. Is it?)... If I put it on a red port, that I think it's SATA I, windows laads the error check, and the message saying "Trying to repair" remains for minutes and minutes. I did't wait it to be completed also, because I dont know if it will end sometime.
