I've had this problem for a few days now, been trying to sort it out and can't get a grip on it.
I have five external hard drives, with folders for various Media Libraries across each of the drives. Lately, files being auto-organized into Drive 4\Television 4 have been failing. Every time. No matter what.
So I navigated to the folders through the Network links in My Computer instead of the direct hard drive links. Everything is there. And I compared the security settings for user permissions between Television 4 and Television 3. They're identical. Everything is identical. At least everything I'm looking at.
So I did a test user-initiated auto-organize, then rebooted to get a "clean" server log. In this test, I moved an existing episode (ER S01E25) alongside my latest problem file (American Ninja Warrior S08E03). Both files are present in sites like TheTVDB.com. ER episode would be transferred to Drive 2\Television 2... and American Ninja Warrior is to be stored on Drive 4\Television 4.
ER = pass.
American Ninja Warrior = fail.
For the sake of brevity, I haven't included server logs testing other series that are stored in Television 4. I've tested 4 other shows with air dates ranging from 2009 to present, and every file fails with the same error report as American Ninja Warrior. And they fail whether they have their original filename or properly structured filename.
Here's the error report. The file attached includes the logs preceding the error up until the "Info TaskManager: Executing Organize new media files"
