So, here's the deal. I'm working on this iMac that wasn't booting up all the way for somebody. It had that problem where OSX's loading bar would get about a third of the way full and then completely shut off the machine (although the recovery system boots fine). I performed a hard drive diagnostic and found that the drive was failing, so I took an image of the old drive and restored it to the new one using Macrium Reflect. The new hard drive passes a short and long diagnostic test, but I have the feeling that this OSX installation might be hosed, seeing as it is doing the same thing on the new drive. Common advice online says to boot from the recovery wizard and try to verify the disk and volume in the OSX Disk Utility. Predictably enough, it found problems, but the "repair" option fails every time with an error 8 of some kind. After that, I tried the "fsck" utility, but that failed too with basically the same error. Finally, I tried clicking the option to reinstall OSX inside of the recovery wizard, but it too always has an excuse, either saying "this disk is locked" or something about it not being "journaled". So at this point, the question is this - is there anything else that can be done at this point short of completely wiping out that disk and starting over with a clean installation? If not, how exactly can I get the documents and whatnot off of it before wiping it out, seeing as they won't mount in Windows and there's no file explorer in the OSX recovery enviroment? If it was my machine, I wouldn't care, but it's not, so I want to keep as much program and personal data intact as possible, within reason.
