WD passport - cannot write on disk (after starting up PC)

I started with my WD passport external drive 1TB. AFter i wrote my maps on the harddisk, i closed down the PC. Then i started the PC. The result was dat i cannot write on the WD passport anymore.

I tried tot format the harddisk. It worked, so i started again. First i can write everything on the harddisk. AFter closing down the PC and restart the PC, i cannot write anymore on the harddisk (read only).

What happened? Is this an Windows 10 issue?

Hi Koendegroote,

We suggest you to please connect the drive with different to see whether the issue persist or not.
