I can't repair the disk
So I recently placed a hard drive into an enclosure because my external hard drive's case was broken..( the USB part). After I plugged it into my laptop, I ended up getting the message "This disk is not readable by this computer" with the options of initialize, ignore, eject. I read other answers to my similar problem & they said to repair it....I went into disk utility to repair the disk, but those options are not available. Anybody know why? or Suggest any help for me?
I wanted to get some files off of the hard drive. And also, is it possible to continue using the hard drive? It was my back up drive.
