If you receive this message from Disk Utility after replugging an external drive that wasn't successfully ejected or unmounted , it could be that the OS is already busy performing the repair in the background. Your Mac will not be able to mount the disk until after the automatic checks are complete.
If the external drive's activity indicator is blinking, but you are otherwise unable to access the drive, then some background process is working on your disk. To see whether this is the case, you can run the "process status" command in a Console shell:. I let it do it's thing for a few hours; when it was done, the disk was automatically remounted and could be browsed in Finder. If nothing above helps remove the HD and plug it into another machine like external and get your files. After that put it back into your Macbook. If you have bootable drive with osx - if not make one- and on start up press cmd.
Boot the Mac with osx and go into disk utility to format it and install new os. If the command prompt returns without any output, then the drive isn't being checked by one of the "fsck" programs filesystem check. Otherwise, if you see a line like the one above, then the drive is busy. Can you still eject your Hard Drive, even though you received the message while you plugged it into your Mac?
The reason why I am asking is because I usually eject my HD by dragging it to the trash icon. Even though I did it, my Mac claims that it wasn't eject properly. The challenge is to backup such disks. Are you able to create a disk image of the drive using Disk Utility?

Now, release it when the boot progress bar indicator will appear. This will boot you into Single User mode and things will suddenly go very Linux, with a text-based display.

Of course, you may never see this because even this trick might not be able to fix your disk.

So with a new 2TB Seagate drive remembering the original question of this string will 'restore' in fact restore all my time machine 'saves' as well as the other files I have backed-up to this 1TB drive. Nobody is answering the question. How do you get files off of a drive that won't boot? The message says to back up your files, but nobody here is explaining how to do that.
Boot from the startup drive’s Recovery HD partition
If you have a PC and an external hard drive enclosure or a hard drive base reader the you could slap the hard drive on it and fix it with the PC. Or at least read the Hard Drive to copy the files of the Hard Drive. That is if the drive is not fully shot. You can also buy an USB adapter to plug into the hard drive, and if the drive is readable, you might get a chance to save your files.

You can accomplish the same thing by opening your PC and plugging the drive into a 2nd connector if available. I can't see the whole thread, and I'm sorry if you have a Mac. Opening these can be an adventure, and I don't think TestDisk will run in this case. If you're adventurous and have a PC, you can try TestDisk, a little utility that has been able to get into a couple drives when nothing else I've tried has been able to. The bottom line, however, is that the life expectancy of a hard drive is years on average Google , and the undeniable fact is that it will fail catastrophically at some point.

To recover files from a non booting Mac, one has to first boot the Mac with a secondary source say a rescue media and recover files from the Mac internal hard drive. This happened to me, too. I ended up getting a CrashPlan account and have backed up the files I can to the cloud. Fortunately, I also have the same files on my Mac, so I've backed those up, too.
What's Wrong with Drive
I'm getting ready to reformat the bad hard drive, so I'll see if my time doing so was a waste or if the drive is again useable. Might be a win-win in that I have my stuff backed up in three places, but if the drive is bad, I still have the cloud and another external drive. Same issue. Hard drive failed completely. I'm not going to be able to access with anything. My guess is that I need to install a new drive, download a new OS, and install it. My only Mac is dead. I don't have access to anything but a Windows PC. You can purchase a OS from many websites like this one. That's what I ended up doing.
And it also seems like most folks who want to help just can't believe that the failed drive is totally useless. Lots of help available to recover it, but they are often simply dead. I appreciate your advice and the trouble you went through.
