Hello. This is my first post but I've been reading here for a while. I'd appreciate any help. Like an idiot, I changed the name of my hard drive. I noticed it was called 'MyData' and thought that was vague, so I changed it to 'HardDrive'. When things started getting weird, I changed it back to 'MyData'. I used it as normal for a few days, and then it froze while I was using Safari - I was unable to do a force quit. When I tried to restart it, I got the blinking folder with a question mark. I followed advice across this forum and was able to restart it twice with the PRAM reset, and used it for another week (without ever shutting down). But then a week later it stopped responding. I then followed advice from this forum and tried to run first-aid using the original install disks. It did not show my hard drive at all. I ran repairs and it said no repairs needed. I then inserted an old copy of DiskWarrior, which it didn't recognise, and it's now stuck in there. Is the renaming of the drive just a red herring and my drive has coincidentally failed at the same time? Or is it not showing up because idiot me renamed it and now thinks it's gone? It's an iMac intel that I bought second hand from my boss, who knows nothing either. Please don't flame me, I know I did a stupid thing. I'm a beginner and I need help, please. Thank you for any advice.
