I don't need it, because all my system partitions are fine. Only the two 
last partition, where there are some audio and work data, refused to be 
mounted.

I think it is a partition table problem because I had the problems after 
having modified it through cfdisk. And the weird thing is that I could 
check the fs on the partition (a forced check didn't give any errors).

In fact, now that my problem is solved, I think I forgot to reboot after 
having modified the partition table; worse, I built a filesystem on the 
modified partition before rebooting, maybe a 40 Gb fs on a 2 Gb partition !

I didn't know how to use gpart on the extended partition.

What I did is just removing all the partitions from the partition table, 
and set the partitions where I knew the beginning/end. It worked, and I 
quickly copied all data on an external hard drive before reformating the 
partitions where the fs size and the partition size were different.

Thanks for you help,

David
