Want to upgrade to 512GB Sandisk X400 SD8SN8U-512G-1122, but want to clone the the whole disc so that all original hidden partitions are migrated too. Doing it with an M.2-USB adapter. Tried with AOMEI Backupper 3.2 unsuccessfully. The system doesn't see a bootable drive at startup. By the way, when connected to a different system via the same adapter, unlike the original 256GB one, Windows explorer as well as Disc Management show all of the partitions at 512GB, but for the original one Disc Management only, Win Explorer shows just one partition. That's another indicator that something is going wrong while cloning.
Acronis Disc Director 12 doesn't allow cloning it, guess because of the running OS on it.
Please help.
