I tried R Tools R-Studio to do recovery
I'm using this drive with Tiger 10.4.11. The backup drive (a different external drive) was accidentally erased, and when I attempted to run a new backup, it kept freezing. I discovered that the Samsung drive had the bad sectors, and every time when a backup program hit a bad sector, it stopped backing up (iBackup, SuperDuper!). I finally tried R Tools R-Studio to do recovery. I managed to save a few folders, but now it can only access very few files, telling me that there is an input/output error or a bad sector. I can't clone the drive, I can't copy files. The drive keeps getting slower and slower. The folder structure is still intact - I can see all of the file names with no access to it. The drive has never been opened.
