I have a Western Digital 1TB USB 3.0 external drive. I am connecting it to the correct (blue) USB 3.0 port on my Acer Aspire 5755-6647 laptop which runs Windows 7 x64.
Upon connection, I get the "This device can perform faster: This USB Mass Storage Device can transfer information faster if you connect it to a Super-Speed USB 3.0 port" message. When copying files off the drive, I get about 32 MB/s, which corresponds to USB 2.0 speeds.
I have tried disabling USB power management in the USB 3.0 Host Controller Utility. I have tried uninstalling the device and reinstalling it. The cable I am using came with the drive and is a USB 3.0 cable. I have the newest Renesas USB 3.0 driver installed (22.214.171.124). I have also tried using an older Renesas driver. My BIOS is up to date (P5WE0121).
I can't figure out what else to do. If it helps, the first time I connected this drive to my laptop, it was on a USB 2.0 port (I had for some reason misremembered which side of the laptop had the 3.0 port and didn't check for blue). As I said, though, I've uninstalled the device completely. I suspect that Windows may be "remembering" the device and installing it with the 2.0 driver.
