Even better, though the file structure for the Wii may be different from Windows or Mac which would complicate things. If the system boots before it freezes, and the OS is stored on the drive, that's a good sign that it's just file corruption and not hardware failure. There are tricks to pulling data from a crapped HDD (unless it's clicking in which case it's toast). You can try freezing the drive in a sealed plastic bag, or installing the drive in an external enclosure. Good luck.
