Mon beau-frère (83 ans) sur W7 familial a un disque externe Western digital My Passport Essential formaté en UDF.
Je voudrais le lui mettre en NTFS mais Formater est grisé.
J'ai trouvé sur internet (peut-être) la solution mais en anglais,
http://superuser.com/questions/127783/format-udf-hard-drive-as-ntfs-in-windows-7
dans l'intervention qui suit:
Note do not partion via Windows or 3rd party software like paragon, otherwise you will mess the WD hard drive.
Connect WD HDD to pc, go to open WD smartware and go to the window inside WDsmartware where you will see update software (right bottom corner).
First download the firmware, install, power recycle WD and then reconnect. Download software update, power recycle again. Now you have an NTFS WD. By doing this way you will not harm the drive and it's always reversable to factory setting (e.g. when you want to sell it etc.)
This solution is also valid for WD passport essential SE owners, after following these instructions you will able to disable "VCD" (UDF) so you have unlimited size NTFS.
