`gpart restore` just uses a number of commands to geom_part(4) to create partition table similar to what was backed up. If your partition table on the old system had a partition that starts from LBA 34, now `gpart create` isn't able to create such partition table. Because by default the first usable LBA is 40. -- WBR, Andrey V.
