wd mybook external hard drive does not work on windows 10 but works on 7

Hello Josephbernado, my name is Irisdiel and I am an independent advisor. I've found some steps and methods you should try that will be a probable solution to our issue.

Check the Power and Data Cable:
-Check that the power cable is securely connected to the external drive and wall socket (applies only to desktop external hard drives).
-Do not connect the drive through a USB hub, connect it directly to the PC or laptop. -Make sure the power adapter is connected directly to a wall outlet, not to an extension cord.
-Ensure the cable is securely connected to both the drive and computer.
-If your external hard drive came with a Y-cable, use both USB connectors to ensure the drive is getting the appropriate power.
-If you are connecting to a PC, use the USB ports found on the back of the computer. -Avoid using USB ports found on keyboards, monitors or the front of the PC.
-If the problem still continues, try using a different USB port.

Check the Drive Partition in Disk Management:
Even though the drive may not be visible on the Desktop or in My Computer, check to see if the drive is recognized in Disk Management.
-Right click on My Computer and select Manage from the menu. (Windows 8 users hold down the Windows key + the X key, then click disk management)
-From the Computer Management window select Disk Management from the menu on the left.
-In Disk Management check to see if the drive is visible. If the drive is found, look at the partition for the drive. New drives will be labeled as NTFS and have a drive letter assigned.
-If the drive does not display as Healthy or shows the file format as RAW, then the partition has become corrupt. It could also be corrupt if the bar above the drive is black and shows as Unallocated.
-To make the drive usable again after a partition has become corrupt or lost start by right-clicking on the drive in Disk Management and select Delete partition from the menu. Then right click on the drive again and select create partition from the menu. Follow the steps in the partition wizard to create a Primary partition.

Check the drive status in Device Manager:
-Right click on My Computer and select Manage. (Windows 8 users hold down the Windows key + the X key then click Device Manager)
-From the Computer Management window select Device Manager from the list on the left.
-From the device list, expand the Disk Drives category by clicking on the [+] or triangle symbol found to the left. If the drive is detected by the system, there will be an entry for your external drive.
-If it is not listed under Disk Drives, expand the Other Devices category and see if there is an entry for an Unknown Device.
-Right click the Unknown Device and select Properties.
-Under the General tab, it will typically display This device is not working properly followed by either Code 10 or Code 28.
-Code 10 would suggest a potential power supply issue (typically 3.5-inch desktop external drives). If a second external drive with an equivalent power supply is available, try connecting the power supply to the drive.

I hope these methods solve your issue. Thank you and good luck. Regards- Irisdiel H.
