Hello,

I have a issue in my Alienware for a long time. I'll try to brief.

As soon as I got this laptop Alienware M17x R4, I have realized that sometimes (not always) my laptop turned off abruptly in the moment I connected any kind of USB device (pendrives and an external hdd) on it. I called the support and they fix that to me changing basically the USB driver. No more crashes anymore, but since then I am not able to connect my HDD. Pen drives work so far.

I've tried many ways to solve it following what was written on forums: I updated BIOS driver and USB driver via dell.com. Again with online chat support. Unfortunately, nothing resolved. I tested my external HDD in other 3 computers(different brands) and it worked perfectly.

I'm using Windows 7 Home Premium and this HDD is a WesternDigital model WDBACX0010BBK-01

I need help from the experts to solve this

Thanks,
