Q: Hard Drive Issue

I have a MacBook Air new in 2013. Running disk utilities, I came across diskOs4. This showed an error message saying the disk had to be repaired. Trying to repair I get the message that disk utility cannot repair it and I need to back up as many files, reformat the disk and restore the backed up files.

 

I have subsequently found out that this is part of the Apple SSD Controller. Is it safe to erase this? How would I save files? How would I reformat this?

MacBook Air, iOS 6.1.4
