I occasionally get that error when moving folders on NTFS disks. The folder I was moving then disappears and can not be found. I am usually able to recover it by running Repair Disk in the Disk Utility (or chkdsk on a Windows system). Except for when this happens, the drive passes chkdsk cleanly and I haven't had any other problems with it. Any ideas? This is the first problem I've had with the driver, but it is getting pretty frustrating and has made this driver worse than useless because of the fear of losing data. I'm on Mountain Lion (10.8.4) and 10.0.1 of the Paragon NTFS Driver. Repair Disk output: Verify and Repair volume “2TB Photo Video” Checking file systemChecking Volume /dev/disk2s1...
