The GPT partitioning format keeps 2 copies of the table of partitions: one at the beginning of the drive and one at the end, and also the info it keeps includes the size of the drive. So when you clone to a differently-sized drive, the 2nd (aka "backup") is inevitably lost/misplaced. This is normal. Notice how the "size mismatch (234441647 != 468862127)" mentions exactly (well, off-by-one) the sizes of your two drives. === Stefan
