WD portable orange 4tb

I use My Passport orange 4 TB drive as my main storage and catalog for adobe Light room on my imac. After I leave it for the night the passport shuts off and is no longer readable, it still shows up as a drive but it is not accessable. I have to uplug and plug it back in. Why does this do that? Is it the drive or does it have something to do with LR

Hello jplansky,

Have you tried turning off the sleep options on your Mac system?

Yes and that didn’t change anything, thanks

Hi jplansky,

Maybe you should try contacting WD’s Technical Support about this.
