I have connected my NTFS drive to iMac (OS 10.6.2) using USB docking station. All the files were visible, but, of course the drive was not writable. After installing the trial version of Paragon NTFS for Mac almost all files and folders on the drive disapeared. Switching NTFS for Mac off, corrected problem, i.e. files apeared again, but of course I could only read the drive. Is there any known issue with connecting the NTFS drive through external docking station?
