Windows & G Drive 4TB - Error: You need Permission to Access this Drive

[Charles2]

I added a 4 TB G drive connected by Thunderbolt cable to my Windows side on Parallels 9 on a New Mac Pro. When I tried to put data on the drive from windows, I get a message: You need Permission to Access this Drive.


What do I need to do to allow access to the drive in Windows?

I never see this message when adding drives to a standard windows PC.

I understand I can attach this to the MAC side and have the drive available for both Mac and PC. I am going to use the hard drive for several SQL databases. Does having the Hard Drive directly connected to the PC vs Through the MAC have a performance impact?

Hi Charles,

Please check whether the permissions for the external drive is accessible on your Mac.



Choose the external drive and right click on it > get info > change the permissions to read & write.
