It is unused, and *UNUSABLE* space (unusable, due to the fact that it is *impossible* to map it with a partition id given your current partition layout). Labeling it as "logical" is, well, not logical, in that it isn't a logical partition. In fact, it's not a partition at all, as noted by the fact that it doesn't have a partition id #). Labling it as "void" would be a more accurate description of this disk space. The only way to claim this space would be to backup everything on the disk, repartition without leaving a "void", and then restore. Since it is only 1 sector big, I wouldn't bother with trying to reclaim it. (It may, in fact, not be reclaimable -- in Linux, partitioning is usually done on cyl boundaries). - -Greg > 4 Primary 219463965 615401954 0 395937990 W95 Ext'd (LBA) (0F) > None > 5 Logical 219463965 223672994 63 4209030 Linux swap / So (82) > None > 6 Logical 223672995 265618709 63 41945715 Linux (83) > Boot > 7 Logical 265618710 615401954 63 349783245 Linux (83) > None > 3 Primary 615401955 625137344 0 9735390 CP/M / CTOS / .
