MagicCute ran for 7 hours and produced a directory hierarchy with NTFS folder at the top, then RAW files folder, then folders containing various files. It is able to see and display some of my photos on the drive. However, it apparently needs to run another scan, this time for an estimated 36 hours. As this is not a registered copy of the program, I can only scan and preview files.
I left WD Data Lifeguard open during this whole test. When I saw that MagicCute wants 36 more hours to run, I told Lifeguard to continue with repairing the bad sectors. It completed in a few minutes, but then said, "Error detected while repairing bad sectors. Please contact WD technical support for help." Windows is still unable to access the drive, though it still shows the drive letter in Windows Explorer.
