SSD하드디스크 추가하기

Tx2의 기본 디스크 용량이 작기 때문에 필수적으로 SSD하드 디스크의 추가가 필요하다.

• 하드디스크 추가하여 확인하기

sudo fdisk -l

Disk /dev/sda: 465.8 GiB, 500107862016 bytes, 976773168 sectors
Units: sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes

• 파티션이 안되어 있을 경우

sudo fdisk -l # fdisk 확인 --> (result) Disk /dev/sda: ~ GB, ~ bytes .... doesn't contain a valid partition table sudo fdisk /dev/sda # 위에서 나온 partition되어있지 않은 disk가 새로 꽂은 디스크다! ---- (이하 fdisk 실행 후 창) Command (m for help): n Partition type: p primary (0 primary, 0 extended, 4 free) e extended Select (default p): p Partition number (1-4, default 1): Using default value 1 First sector (2048-1000215215, default 2048): Using default value 2048 Last sector, +sectors or +size{K,M,G} (2048-1000215215, default 1000215215): Using default value 1000215215 Command (m for help): p Disk /dev/sda: 512.1 GB, 512110190592 bytes 255 heads, 63 sectors/track, 62260 cylinders, total 1000215216 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0xe8bf195f Device Boot Start End Blocks Id System /dev/sda1 2048 1000215215 500106584 83 Linux Command (m for help): w The partition table has been altered!
