Some audio (wave) files on my computer have suddenly been corrupted for no
apparent reason. When I try to play these I get an error "Invalid file type"
I can fix this by copying the header information from a non corrupted wave
file into a corrupted one. However I still get an error: "Unknown CODEC" ...
As far as I know it is impossible to fix this, however if anyone has any
ideas?

You might try using Gidluck Mastering's WaveScript to salvage the file.

Rename the file to .raw, then use SOX to convert to .wav (something like
$sox -c2 -w -s -r44100 file.raw file.wav
assuming 44.1, stereo, signed, 16 bit).

Then you will need to remove the click that has probably been introduced
by reading the header as audio, but that should be easy.

I consider sox to be an essential tool for hacking around with audio
file formats.

Immediately you should run scandisk. If you find errors and it takes
forever, run it again. If you keep finding errors, your HD is going bad, or
you have some type of nasty virus.. Usually it is simply bad sectors. I
strongly urge caution and a complete backup. I have been through this
before... it can get ugly if you don't take steps and check out the health
of your drive. If it is going bad, the sooner you know the better...

Good luck: )
