Thanks in advanced for your support.
Yesterdays morning, mi computer power off itself due to battery power gets down. After this no longer boot.
I have tried some thing by myself - error!!!!!!! - and at now it seems testdisk is unable to recover things.
I lose any hope of recovering it all, but unless home partition is important for me.
Find below the output of deep search within testdisk, could you give me any hint?

The harddisk (320 GB / 298 GiB) seems too small! (< 404 GB / 376 GiB)
Check the harddisk size: HD jumpers settings, BIOS detection...
The following partitions can't be recovered:
