Schau Dir mal SpinRite an. Das prüft und repariert (!) die Hardware. Geld zurück Garantie. l/i

Na, da braucht man aber schon Optimismus:
SpinRite 6.0 is NTFS, LINUX & TIVO Compatible!
SpinRite v6.0 recognizes and operates on ALL file systems. It can even be used to repair and recover Apple Macintosh and Tivo hard drives by temporarily moving them into an Intel-based PC. It can also be used to check the health of drives that have not yet been formatted.
SpinRite v6.0 brings along and automatically boots a copy of the FreeDOS operating system, so it will run even if you have no "DOS". It can create bootable diskettes, CD‑R's, USB Flash drives and other media.
