WD My Book, Windows 10 not recognising

i used to use this on old PC with Win 7, recently found drive again and want to check the contents. But my Win 10 is not recognising it. I am pretty sure it is working and I can see it on device manager.

crystal disk tells me it is healthy.

Hello,

Please refer to the following KBA article: Cannot Find My WD Drive on Windows or macOS

If you had tried the drive in another system & it is working it means that there is no issue with your drive & it is still healthy, just not recognizing. You can try below fixes to resolve the issue:

  1. Initialize the drive or drive partition
  2. Change/Assign drive letter
  3. Update Disk drivers
  4. Enable drive in BIOS

& hopefully it will helps!
