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" or "void space" would probably 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. - -Greg > 4 Primary 39070080 976768064 0 937697985 W95 Ext'd (LBA) (0F) None > 5 Logical 39070080 78124094 63 39054015 Linux (83) None > 6 Logical 78124095 117194174 63 39070080 Linux (83) None > 7 Logical 117194175 156248189 63 39054015 Linux (83) None > 8 Logical 156248190 195318269 63 39070080 Linux (83) None > 9 Logical 195318270 203125859 63 7807590 Linux swap / So (82) None > 10 Logical 203125860 976768064 63 773642205 Linux LVM > (8E) None > > >> # cfdisk -Ps >> Partition Table for /dev/sda >> >> First Last >> # Type Sector Sector Offset Length Filesystem Type (ID) >> Flag >> -- ------- ----------- ----------- ------ ----------- -------------------- ---- >> 1 Primary 0 128519 63 128520 Dell Utility (DE) >> None >> 2 Primary 128520 219463963* 0 219335444*HPFS/NTFS (07) >> Boot >> Logical 219463964* 219463964 0 1*Free Space >> None >> 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 / .
