Thanks herbfargus for your reply!
(I try to make the fat partition on sd card to copy the roms because my friends dont know make a sftp connection and whit this partition is too easy for them)
I resolved my problems if anyone need I write the solution here:
1-Retropie and binary updates are install with 4Gb (enough space)
2-You can use Paragon Partition Manager to resized the expand ext4 partition of retropie (in windows)
3-In new jessie versions (3.3 and more updated) the uid=1000 gid=1000 for this reason the option line of fstab look like this
auto,users,rw,uid=1000,gid=1000 0 0
to mount usb ((using them I can save/load without any problems))
