Hi. Commands executed: # dd if=/dev/zero of=/dev/sdc
# parted /dev/sdc (parted) unit s print free Error: /dev/sdc: unrecognised disk label Model: (...) (scsi) Disk /dev/sdc: 15638480s Sector size (logical/physical): 512B/512B Partition Table: unknown Disk Flags: (parted) mktable msdos (parted) unit s print free Disk /dev/sdc: 15638480s Partition Table: msdos Number Start End Size Type File system Flags 2s 15638479s 15638478s Free Space Disks' sizes calculation model, involved in the calculation of values related to disks, appears to be incorrect. Here an illustration from above output, assuming that disks start from sector 1; according to that assumption correct calculation model regarding disks' sizes is expected to be: Disk <path> = *Size* + (Start - *1<size_unit>* = 15638478s + (2 -1)s = *15638479s*. However exhibited Disk /dev/sdc size is 15638480s. Regards R.T.
