Access is dennied

[SamItIs]

I have a WD 1 TB MyBook which I use for backup. Last I used it was 3 months and it was working. I upgraded from Win7 to Win10 last month.Now I can not access it. I get msg

F: Is not Accessible
Access is denied

Device Manager shows:

WD SES device, properties shows “device working properly”. Driver info:
Date 10/9/2015
Ver 1.1.0.0
Driver location C:\windows\system32\drivers\wdcsam64.sys

I try to upgrade driver and system says it is already upgraded.

Disk Management shows the hard drive recognized F: with 2 partitions. One is about 1 TB which is what I expected.

Anyhelp is appreciated. I now

Hi, you will need to take ownership of the entire drive in order for you to be able to access the information, take a look at this and it will explain you how to go about it.
