I have three of the plugable usb 3.0 hd docks. I’m having a problem with two of them not recognizing 3tb hard drives. These also happen to be the two that I bought together a while back. The one I bought a couple months ago works fine with both 3tb drives that I have.
The two docks that are having problems with the 3tb drives work fine with my 2tb (and less) drives.
The 3tb drives (in the two docks that aren’t working) do show up in Disk Management/Storage Management. However they show up as unitialized and unallocated. When I try to initialize them, I get error: The request could not be performed because of an I/O device error. I’ve tried both GPT and MBR…both give same error. Once again, the drives work fine in the newer dock. They come up initialized and have been formatted, working fine, etc.
I’ve upgraded the firmware to: LUCIDPORT U300 Sata/Usb 3.0 Controller firmware 2580. Still no go.
The docks are connected via your plugable pci-e expansion cards…latest drivers installed.
The variable that seems to be the consistent culprit is the 3tb size.
Do the old docks not support 3tb drives? Your help is appreciated.
