For the past few weeks, my external 1TB Hitachi Hard Drive has been sporadically disappearing and I was able to unplug it and plug it back in and then it would be there again. Today it disappeared and it will not come back. I've tried plugging it in to another computer and it installs itself there and then says there is nothing on it.
It gives me a message when I unplug it and plug it back in that says "You need to format the disk in drive M", but I don't want to format it because all of my data is hopefully on it. It says I have 0 free space and 0 used space.
Can anyone help me with this? I started using an online backup service and thought my files were being backed up but when I checked it says that my M drive was selected for backup but that it was not backed up because it is unplugged.
