I have three 500GB WD Essential drives WDBACY5000ARDs. These have always worked fine, then over the weekend I updated to OSX10.7 Lion. Now my drives won’t stay connected for more than a couple of minutes and the following prompt comes up:
“The disk was not ejected properly. If possible, always eject a disk before unplugging it or turning it off.”
This happens on all three drives on my MBPro with Lion. However, the drives work perfectly fine on a second macbook pro I have without Lion on it. I updated the drives to latest firmware and even installed latest smartware. The same thing continues to happen.
Any help or advice would be greatly appreciated.
