Voila ce qui a dans la partie "troubleshooting" du programme que tu as utilisé :
I have installed the Ext2 IFS software and was able to create a drive letter for a desired volume of Linux. But when I try to access that volume I get an error message "The disk in drive X: is not formatted. Do you want to format it now?" (Of course I don't want to!) Or the content of the volume appears, but when I attempt to write something I get an error message "Access denied".
The ext2fs.sys driver did not mount that volume for some reason, or it mounted it read-only.
Please run the mountdiag diagnosis tool, which you can download here: mountdiag.exe.
Please run it at the command prompt and give it the letter of the drive you want to examine, for example:
mountdiag G:
The tool will give you a hint on how to resolve the problem. (Note: The mountdiag tool reads data only; it does not attempt to modify anything.)
Donc en gros, ils disent de télécharger Mountdiag, et de taper dans excécuter : mountdiag lettre_du_lecteur_en_question. Ca permet de savoir pourquoi ca foire. Ensuite, il faudra configurer en fonction de ce que Mountdiag répond.
