I just got my new AW13 this week and I really like the system, but wanted to swap out the 1TB HDD with a 500GB SSD.  

I got a Crucial MX100 and used Acronis to copy all of the partitions from the original drive to the new.  I had the SSD in a usb external enclosure and the system had no problem seeing the drive at all.  All seemed well until I moved the SSD into the laptop from the external enclosure.  The laptop does not recognize that a drive is connected when I have the SSD plugged in directly to the SATA port on the MB.  

Here is what I have tried so far...  I checked to make sure I had a clean connection from the sata cable to the SSD drive and it looked good.  I check the connection on the SATA cable to the MB and that was fine(unplugged and reseated).  I put the old HDD back in the system and it fired right up.  I put the SSD back in the USB enclosure and it was recognized and accessible.  I checked in the bios for any settings that would relate to HDD and didnt really see anything work messing with.  There is no raid option, so UHCI is the only option.  I called Crucial and asked them, but the laptop is so new, they don't have much info on it to be of much help yet.  With the drive working when connected to USB, he concluded that maybe it was something specific to the cable that was non-standard or maybe something in the bios.  I posted on the notebookreview forums and someone else had the same experience with another crucial drive, but tried a samsung drive and it worked fine on their AW13.

I wanted to check here before I call into support to see if anyone has had similar experiences and resolved the issue.
