virtualbox centos usb 리눅스 외장 하드디스크 포맷 방법

virtualbox에 usb 외장 하드 디스크를 인식 시키는 방법과

centos에서 외장 드라이브를 포맷하는 방법을 정리했습니다

---

host 컴퓨터는 windows입니다

외장하드를 usb로 인식시킨 상태 입니다

host컴퓨터에서 인식한 외장하드를 virtualbox내부 centos에서 인식하도록 설정하는 방법 입니다

virtualbox 메뉴중 '장치" -> "USB 장치" -> "Seagate BUP Slim BK"를 선택합니다

선택을하면 해당 라인에 V 로 체크가 됨을 확인할 수 있습니다

Seagate BUP Slim BK 이 이름은 각 외장하드 드라이브 이름마다 다릅니다

virtualbox에서 인식을 하면 host컴퓨터인 windows에서는 해당 드라이브가 목록에서 사라집니다

지금 부터는 centos내부에서 외장하드를 포맷하는 방법입니다

fdisk -l

리눅스에 마운트 된것을 확인합니다 

외장하드가 /dev/sdb1위치에 NTFS타입으로 있음이 확인됩니다

fdisk /dev/sdb1

fdisk는 디스크 파티션 관리자 입니다

이 명령어로 /dev/sdb1에 마운트된 외징하드의 파티션을 지우려고 합니다

p 를 명령

/dev/sdb1로 마운트된 디스크의 파티션을 확인합니다

m 을 명령

fdisk에서 사용할 수 있는 명령어 모음 입니다

d 를 명령

기존에 있는 파티션을 모두 삭제합니다

저는 1번부터 4번까지 삭제를 진행 했습니다

p 를 명령

파티션을 모두 삭제한 현재 디스크의 파티션을 다시 확인합니다

n 을 명령

p 를 명령

엔터

엔터

새로운 파티션을 생성합니다

w 를 명령

설정한 파티션을 저장하고 나옵니다

mkfs -t ext3 /dev/sdb1

/dev/sdb1에 마운트된 디스크를 ext3형식으로 포맷중입니다

ext3 형식으로 포맷이 완료 되었습니다

mount -t ext3 /dev/sdb1 /mnt 

/mnt 위치로 외장하드를 마운트를합니다
