When I try to write start 1024 it writes 1024mb not 1024s and for end I write 18464767 and it recognizes it like 18464767mb not 18464767s I have like this: (parted) print print Model: MMC HYNIX (sd/mmc) Disk /dev/mmcblk0: 14,80GB instead of 31047680s Sector size (logical/physical): 512B/512B Partition Table: msdos how do I change to sectors not gb?
