Mouais je vais voir avec easy recovery mais c'est galère...

j'ai noté ça :

The images are extracted as 'iso' files and they will be split into 3.999Gb chunks if a FAT file system is found.
[b]In this instance a dummy 'MDS' file will also be created so as to allow WinHIIP to reinstall the image when required. [:b]
This 'MDS' file is not a valid DVD Decrypter file and therefore will be of no use if used with that product.

je me demande si c'est pas ça qui ma foutu la merde...
