I have a strange problem. Working on an OS 10.9.5 MacBook laptop.
Last night, I was exporting a 20-something GB Aperture library from my WD 2TB drive to another hard drive. I left, and when I came back the next morning, my computer warned me that I should properly eject my hard drive. I hadn't disconnected it, and my settings are set so that the computer will NEVER go to sleep or shut down when the power supply was connected (which it was). Now, my mac won't recognize the hard drive.
- Is it dead?
- How can I prevent this from happening again?
- How can I recover my files if I can't see the disk???
- Powering my computer on and off
- Using a different USB connector
- Using a different power cord
- Plugging the external drive into another mac (did not work)
- Plugging the drive into a windows computer (nope)
- Mounting through disk utility, or using disk utility to repair/verify the disk (got this error message: Disk utility can't repair this disk. Back up as many of your files as possible, reformat the disk, and restore your backed-up files).
- Suggestions on these sites: External drive does not mount after plug off without eject and Sometimes Mac doesn't recognise my external hard drive e.g., going through terminal to unmount OR eject OR view files in read only mode (all just say the volume timed out)
- Read suggestions on this thread about drives disconnecting on their own - wasn't sure what to do, but realized the problem might have had something to do with exporting Aperture files? https://discussions.apple.com/thread/2597920?start=120&tstart=0
This is my time machine disk, and it has some other stuff on it I need. I also don't know whether to trust my machine to plug another hard drive into it. I can't update to a newer OS just yet. I'm terrified to plug in my other hard drives because what if the same thing happens to them!? Unfortunately all my Aperture libraries are stored on external disks!
