I have just recently purchased a “USB 3.0 SATA Hard Drive Docking Station Enclosure (USB 2.0 Compatible)” from Amazon, and can’t get it setup on Macs running 10.7.4 (Air) or 10.8 (Pro). I have tried using both the USB2 and USB3 cables. I have an unformatted 1TB WD 3.5 drive plugged in.
The Macs recognize the device and I’m able to see it inside Disk Utility. The problem happens when I try to erase or partition it: when I start it, it just gets stuck on “Unmounting disk” forever, and without any useful error messages.
Here’s some specifics for the dock from Mac’s System Information:
Product ID: 0x55aa
Vendor ID: 0x174c (ASMedia Technology Inc.)
Serial Number: 100000000000000051D9
I originally thought it was a hardware failure, but then I tried setting it up on my (really) old Windows XP computer and I was able to setup a NTFS partition and store stuff on it without any problems at all.
Do you have any ideas?
