Most hard drive manufacturers offer free software that makes it easy to migrate from one hard drive to another. Maxtor, for instance, offers Max Blast provided one of the drives is a Maxtor. As long as the software can access the hard drive (the hard drive failure message usually means that failure is imminent, not that it has already occurred) it can clone the hard drive, copying everything, including the operating system, from the old drive to the new one. That would solve both the loss of personal files and the OS language problem in one swoop. (Everything would be exactly as it was with the old hard drive.)

Best of luck.
