The power comes from the ac adapter being external while still using the onboard sata controllers to get around any potential usb issues! The new one recently order is a Sambrent USB 2.0/eSata enclosure that takes Sata I and II drives not being quite rated for S3 models while those still work since the 1tb in it is just that a Sata III drive! The eSata will be put to use once I can make the space where the printer and some other equipment is sitting on top of the cabinet section of the computer desk here as well as get around to plugging the two eSata cables in from the ports on the case itself. Here I had simply given up on the factory enclosure and a separate Acomdata model years back.


From what I keep finding when looking at the numbers WD hasn't ever been able to get this problem cleaned up over the years since first models saw the same problems as you are now. I put a red mark on each side to indicate which one while the model information will identify which one anyways. Once the drive is detected it appears on top. Here I will the drive in the enclosure with on/off switch turned off and only see the two OS drives and two storage/backup drives listed under Disk Drives until hitting the switch. One place of the two places you can look to see if there are any yellow marked items would be under the Universal Serial Bus Controllers section at the bottom as well as taking a look in the Disk Drives section. I also was finding data transfers were going much faster when 3.0 flash drives were on 2.0 ports instead of 3.0! The 3.0 bus simply provides more current to allow for 6 devices rather the limit of 4 seen with 2.0. I have several 3.0 flash drives recently added to the collection of flash drives here when 10 was first out that are plugged into a large 7 port 2.0 hub at times without any hiccups.

Generally anything 3.0 will work on the 2.0 ports without any problems.
