Hello Apple users. I been doing some research for several days to understand what happened to some of my folders residing in my external hard drive. I´ll try to give as much information to seek for help since most of the topics related to error -43 point to Recovery Software solutions (mainly posts with marketing focus). I have an external hard drive SeaGate Free Agent Desktop 500GB which is formated in NTFS file system. I been using this hard disk without any problems under Microsoft OS, until I switched to Mac OS. Since Mac OS doesn´t support NTFS modification directly, I installed Paragon NTFS so I could modify files within my MacBook Pro. After trying to move a folder from one location to another (within the same hard disk) I got an error 43, after clicking on Ok to continue, the folder disappeared. I been trying to locate it within the Trash Folder, showing hidden files, I even tried some recovery software that could show up lost of deleted files in Hard Disk but nothing worked to get the folder back. I would like to know if some of you have experienced this error before and if you have any ideas where I could locate the folder or where could it go after showing that error, or any procedures to recover my lost folders. Thanks for your help, any additional information you require I´ll be glad to share it.
