Hi all, I just had a really weird problem a few minutes ago. I mounted my Truecrypt container because I do all my work within Truecrypt. Once I had mounted the Truecrypt partition I could see all of the folders and files in Finder, but when I clicked on folders there was nothing inside the folders! Earlier I had opened an OpenOffice .doc file and I was still able to work in the file itself. I tried dismounting the Truecrypt partition multiple times and re-mounting, but the problem didn't resolve itself. I then tried to reboot my Mac Mini and it got stuck on the grey screen. I then rebooted my Mac by holding the power switch and it rebooted and I was able to access my files like normal. I have a feeling the problem was with the 'Finder'. What does this all mean? Does it mean my HDD is about to die? Thank you! Edit: If my HDD is about to die is there any way I check its health? I've been using this Mac Mini as my main system since May 2012 and I've never defragged it.
