Today for some odd reason the finder decided to quit working. This wasn't the normal crash or freeze that the Finder experiences, this one was much, much more serious. It all started when I tried to archive a file. The system told me it could not create a content list. I tried this on a few other files, same error. Then I push the back button and.. HOLY CRAP. WHERE DID MY FILES GO?!?!?! I check elsewhere on the drive and EVERYTHING is gone. Everything except for the currently running applications and the files they had locked. I was pretty sure the finder was just having a big malfunction, so I tried running one of the apps in the dock that weren't shown in the finder anymore. It worked. I relaunched the finder, same issue. Path finder had no trouble seeing all the files, so I know it wasn't a kernel bug. Upon further investigation I found that the Finder had incorrectly counted how much space I had left on my external drive. It's 250 total, and last I checked only 170 was left. However, the finder now reported that only 20 gigs was left, and my internal hard drive had lost 2 gigs. Then it just got worse from there. All my sidebar shortcuts were progressively disappearing as if their references had been removed from the system. I opened a terminal and ran top so see if maybe some rogue process was going insane, but there was nothing. A quick reboot fixed all but the sidebar shortcuts. So, just out of the blue the finder decided to scare the **** out of me. How nice. Thank you Apple. edit: Forgot to add: The finder is now using an ungodly 400 megs of RAM since the reboot.
