I dont have the time unfortunately to read the entire thread, so I hope Im not repeating anything, anyone else may have mentioned... This has happened to me a good few times... and it has meant me losing a great deal of data because of it... When writing from drive to drive, or from drive to media (cd, dvd etc etc...) The data transfer is buffered... and sometimes you will encounter buffer over run... its suppsoed to sync the data transfer so its not reading faster than the writing, or visa versa... And what happens is the file header data gets corrupted... If you "view hidden and syatem files" you will notice there is a windows file named thumbnails.db... which is essentially the saved thumbnail file... which is why the thumbnail's all look fine, even though the file itself is corrupted... Unfortunately, I dont think there is a header repair application to my knowledge :(
