It is starts today. It happened with the external drive connected to the WD LIVE DUO via USB. After that error window Drive is in the read-only mode. I check the drive and repair all the errors using connection to the MacBook Pro and Disk Utility. Then I connect it back to the MyBook Live Duo, and thats happens again. So, what is a solution? Thank you.
Hello, what format type (NTFS, HFS+, etc.) are you using for the external hard drive?
I am using HFS+.
Here is a picture of the error window.
