External HDD won't mount
Hello,
I was working on my external hard disk drive called 'Reserve', when the elektricity on that hard drive went out. When I wanted to re-connect my external hard drive to my MacBook Pro it showed the following message:
In other words, it didn't recognize the external hard disk drive 'Reserve'. When I clicked 'Initialize...' I got into Disk Utily where it showed the HDD, but without the partition 'Reserve':
There are some important files on it that I don't want to lose.
I've already looked up some stuff online, but as I'm not a computer expert, I have no idea what there talking about. DiskXsX and stuff like that... No idea.
If anybody could help me...? Please explain in a clear way. For dummies.
Thank a lot in advance!
MacBook Pro, OS X Mavericks (10.9.5)
