No idea what it can be but whenever FCP starts behaving badly in any way a good first step is always to trash the preferences using this app
I'm not saying it will cure it but corrupted preferences can lead to a tremendous number of diverse problems.
I have the exact same problem. I just opened Final Cut Pro X and all my Projects and Events are missing from inside FCPx They are on the Internal HD in Movies, but FCPx will not find them. I too tried to double click the project file (currentVersion.fcpproject) and it will not open.
What the **** is going on. I have about 50 project folders in mine. 9 are my own projects and 41 are folders from Lynda.com exercise file folders.
I work on this stuff on Friday and today, Monday it's just gone. There isn't one thing in my FCPx program.
Does anyone know what is happening and how to fix this.
Mac OS 10.7.3, MacPro 12 core Intel Xeon, 24 GB RAM
I know this suggestion may seem a given, but is it possible that the Final Cut Events or the Final Cut Projects folders have been renamed?
The naming of these folders has to be exact, and MUST be located in either the ~/Movies folder at at the ROOT of a drive, either internal or external. ALSO, (again a given and obviously not a issue with the system drive) the drive must be a HSF+ formated drive or FCPX will NOT see then events and projects.
Other than that, following Ian's suggestion to reset the preferences, try also repairing the drive permissions using Disk Utility.
Thanks for the suggestions. Unfortunately nothing works. My folders: Events and Projects, are all in the Movies folders at the root level where they are suppose to be. These files and folder have been in FCPx for several months. As I said earleir, I wroked on them Friday and today - Monday they are all gone from the program.
I've taken out the Lynda.com exercise files from the Projects folder, since I read somewhere that FCPx can't handle lage numbers of Projects. Now I have about 9 projects and related events. They have not been renamed (been working with FCP since version 1 and Premiere since version 1 - I know you can't change any names - ever.)
All media is being stored on the internal system drive. As you said, obviously it's HFS+ Journaled.
I've run Disk Utilities - Disk Permissions twice.
Dumped the P-RAM
Dumped all the Preferences Files
Turned off Time Machine.
Nothing has worked. Everything is all gone. It sees all 3 of my internal drives within the program. It even sees the Project and Event folders as it loads, I see all the names go by (real fast) but nothing is in the program when it finishes.
It's as if I just installed the program for the first time.
I just think this progam is totally screwed up. Some update or something is not right. But I'm still screwed. Had to get a project out today. Not Now.
The fix was that everytime there is an Update, you have to say you want it to update all files - projects. if you say no like I did (I thought it was updating files from older FCP Studio), then it doesn't update to the newest version and therefore it doesn't see the files.
Once you update everything, it's all good again - it was all good for me.
It was not updating files from FCP Studio, just Final Cut Pro X. It just sounded that way when reading the info box that came up.
I got the answer from a FCP X Support Agent.
Hope this helps.
I had the same problem os 10.8.5 with an internal 2nd drive in an optical bay in a early 2011 macbook pro.
I fixed it thus:
1) Select the drive not being seen.
2) Right click and "Get Info"
3) Verify that the format is Mac OS Extended (Journaled)
4) if so, check if "Ignore ownership on this volume" is checked.
5) If not, click the padlock icon to unlock
6) Check the "Ignore ownership on this volume" checkbox
