[bu1hamilton]

I have (1) 640gb, (2) 500gb wd passport and had no problem with them. just bought a 1tb and it keeps giving me a "can't eject because device is in use" while i'm transferring files from one to another, then finally the 1tb will just eject itself???????...all the hard drives are formatted the same...exfat. any help????

Error: "WD My Passport 0740 Media is in use and can't be powered off."

it says this about ten times then dismounts with this code:
"The operation can’t be completed because one or more required items can’t be found.
(Error code -43)".

This is the EXACT same issue I have been trying to fix for the past 2 months. According to other posts on other sites it was suggested that maybe some of my folders had characters that were not allowed. I have since gone in and carefully eliminated all bad characters, but my 2nd external drive continues to dismount within 5-10 minutes of my transfers from 1st drive to 2nd drive.

Any help is appreciated.

worked for me

After reading another thread, I went into my applications folder and uninstalled the WD Smartware software. Seems the software was interfering with it's own drives. Hope it works.
