external hard drive won't mount
I have an external hard drive that i was using last week to back up iphoto, now can't be mounted. I have gone into disk utility and both verified and repaired the drive but it won't let me mount it. I am using Mac OSX 10.7.2.
I am not sure what else to do without reformatting the drive and losing all the data.
AppleTV 2, Mac OS X (10.6.8)
