리눅스 펌웨어에서 하드 포맷하기 (ATV7)

안녕하세요. 도정진입니다.

개인적으로 시간이 너무 없어서 개략적으로 적습니다.

1. u5pvr-unmount-atv7.deb 파일 받고 설치

root@u5pvr-debian:~# wget http://u5pvr.djjproject.com/u5pvr-umount-atv7.deb

2. 현재 마운트 된 리스트 확인 후 언마운트

root@u5pvr-debian:~# ls /mnt/media_rw

sda1        <-- 요놈

# 여러개가 존재할 수 있습니다. sda1 sda2 sda3 ... 모두 언마운트 해 주세요.

root@u5pvr-debian:~# umount_disk sda1

umount: /storage/sda1: mountpoint not found

umount: /mnt/media_rw/sda1: not mounted

[info]sda1 is succesfully unmounted.

3. 파티션 작업 후 포맷 작업하기

# 장착하신 하드에 따라 sda 인지 sdb 인지 혹은 sdc 인지 등등 다릅니다.

root@u5pvr-debian:~# fdisk /dev/block/sda

Welcome to fdisk (util-linux 2.25.2).

Changes will remain in memory only, until you decide to write them.

Be careful before using the write command.

# 현재 존재하는 파티션 모두 삭제

Command (m for help): d

Selected partition 1

Partition 1 has been deleted.

# 새로운 단일 파티션 생성

Command (m for help): n

Partition type

   p   primary (0 primary, 0 extended, 4 free)

   e   extended (container for logical partitions)

Select (default p): p

Partition number (1-4, default 1): 1

First sector (2048-234441647, default 2048):

Last sector, +sectors or +size{K,M,G,T,P} (2048-234441647, default 234441647):

Created a new partition 1 of type 'Linux' and of size 111.8 GiB.

# 변경된 설정을 디스크에 씀

Command (m for help): w

The partition table has been altered.

Calling ioctl() to re-read partition table.

Syncing disks.

# ntfs 로 포맷할 경우 아래의 패키지 필요

감사합니다.
