Hello, Thank, THis is the result of gpart (no -f) My problem is to guess where was the extended partition. In addition there was a swap partition is sdd5 Begin scan... Possible partition(Windows NT/W2K FS), size(13mb), offset(6696mb) Possible extended partition at offset(10106mb) Possible partition(Windows NT/W2K FS), size(12197mb), offset(12197mb) Possible partition(Linux ext2), size(500mb), offset(28811mb) Possible partition(Linux LVM2 physical volume), size(71711mb), offset(29312mb) Possible partition(Linux LVM2 physical volume), size(40960mb), offset(101025mb) Possible partition(Linux ext2), size(43000mb), offset(154786mb) End scan.
