The other day I bought the OS X Lion from the App Store and it installed successfully on my Macbook Pro. Today for the first time I connected my external hard drive to my laptop but it couldn't be detected. I also connected another of my external hard drives as well as my USB flash drives and none of them could be detected or read by my laptop after I installed Lion. Can anyone help?
