I'm trying to recover movie files from my TNT receiver hard drive but it corrupts its FAT32 allocation table (crappy cheap device...)

Using dosfsck is useless because the correct file length is the cluster length, not the (shorter) one in the table, and dosfsck only proposes to shorten the file, which I won't do.

Question: how to recover a file using the FAT cluster chain instead of using the stored length in the FAT table?

Edit

I forgot to say: Linux solutions only please (I have no windows box)
