Problem with External HD mounting and Disk Utility
Hi. I'm using OS-X Yosemite (10.10.3) on a 15" MacBook Pro Retina
I've been using my 2TB WD My Passport Ultra hard drive since around February of this year.
Earlier today when I plugged it in, the Hard Drive didn't show up in my devices in finder. So, I unplugged and tried again. Still nothing. Then, I went to Disk Utility and found that the drive was there, but the partition wasn't mounted and is greyed out. So i tried to verify / repair the disk but have gotten a couple different messages. One being: The partition map needs to be repaired because there's a problem with the EFI system partition's file system The other being Some information was unavailable during an internal lookup This message has shown up more than any other.
I've been able to get in and look at my files once to try to copy the files from the drive after a message popped up and said: Couldn't repair the disk, but I could still open or copy files on the disk but can't save changes to files on the disk
But, I encountered an error that was something along the lines of Operation couldn't be completed because the item "..." is in use. But the file I was trying to copy wasn't open or in use by any program.
SO, I'm in pretty desperate need of some help with this. I have some very important files on this drive that I can't afford to lose. A lot of it irreplaceable. Any help at all would be very much appreciated! Thanks a lot!
