외장하드가 인식이 안될때

된장. 외장하드는 진짜 조심해서 관리해야지 한번 맛이가면...

맛가기전에 진짜 조심해서 사용해야함. 끝낼때 항상 Safely remove.... 꼭 사용.

1. Windows Explorer에서 드라이버로 인식하는지 확인
2. Device Manager에서 인식하는지 확인
3. Disk Manager에서 인식하는지 확인

이 정도 된다면 아주 나쁜 상태는 아님.

그럼,

1. Windows Explorer에서 Disk Scan 실행할수 있는지 해봄
2. Data가 중요한게 없으면 그냥 다시 Format하면 됨. T.T
3. Device Driver를 uninstall후 다시 설치하고 update해보기
4. CMD line을 admin으로 실행시켜서 chkdsk /f D: 로 실행해 보기

아래와 같이 복구가됐지만 파일과 디렉토리는 안보임. 그래도 파일 리커버리 프로그램을 돌리면 됨.

File Scavenger

Recuva

등 많이 있음. 파일 많이 복구하려면 돈 내라고 하기도하고...
