I have 2 MyBook Essential 3TBs and 1 MyBook Essential 2TB drive. All are USB 3.0 drives.
The two 3TB drives work fine. However, the 2TB is no longer recognized by my desktop computer. It works fine on my laptop (USB 2.0 connection, not 3.0). It’s worked fine on my desktop for quite a while, but started flaking out by sometimes not being available. Thinking that the cable might be bad, I replaced it. The computer still will not recognize the drive as a harddrive.
I’ve deleted and reinstalled the USB 3.0 drivers (NEC/Renesas). I’ve used an older driver package and I’ve used the latest driver package for my ASUS P7p55D-E Pro motherboard, but it simply will not recognize these drives. Again, no problem with the 3.0 TB drives. I’ve tried it on the built in 3.0 ports and ports I have on a card that I’ve installed, no dice. It doesn’t work on the USB 2.0 ports either.
When I plug in the drive on my desktop, Device Manager shows two entries under the USB Controllers section for “Unknown Device”. The other two USB 3.0 drives show up as NEC Electronics USB 3.0 Host Controller and NEC Electronics USB 3.0 Root Hub (one of each driver per drive, so two sets of entries).
As I mentioned earlier, it worked fine for a long time and still does on the USB 2.0 port on my laptop. My desktop, however, refuses to acknowledge that whatever is hooked up to the port is a harddrive.
I’m really not sure what to do at this point. I’ve done all the troubleshooting I can think of doing. Any suggestions?
