최근에 반복적인 딸깍 소리가 나기 시작한 오래된 iMac 2011에 1TB 하드 드라이브가 있습니다. 이는 CD-ROM이 CD의 "스크래치진" 표면을 읽으려는 것과 유사합니다. 최근에 컴퓨터가 OS 부팅을 중단하고 계속해서 OS를 "로드"하려고 시도했지만(부팅 중에 Apple 로고와 일반적인 진행 표시가 표시됨) 성공하지 못했습니다. 물론 컴퓨터에서 큰 클릭 소리가 계속 들렸습니다. 운영 체제. 운전하다.
썸 드라이브에서 Linux로 부팅했는데 모든 것이 잘 작동했습니다(사실 라이브 OS에서 부팅했습니다). 그래서 디스크 드라이브에 문제가 있는 것 같아요. 하드 드라이브의 모든 파티션을 실행 gparted하고 삭제했는데 이제 전체 1TB 공간이 unallocated여유 공간이 되었습니다.

Linux디스크를 휴지통에 버리기 전에 복구할 수 없도록 하는 데 사용할 수 있는 도구나 기술이 있습니까? 내 말은, 193개의 불량 섹터가 보이는데, 이는 디스크를 복구할 수 없다는 뜻인가요? 불량 섹터가 복구되거나 더 이상 사용되지 않도록 소프트웨어를 사용하여 드라이브를 포맷할 수 있습니까? 하지만 디스크의 나머지 부분은 계속 사용할 수 있습니까?
추가 정보: 드라이브에서 데이터를 복구하는 데 관심이 없습니다. 디스크 상태를 확인하기 위해 여기에서 제안한 도구의 결과를 표시할 수 있습니다.

답변1
"반복적으로 클릭하는 소리"는 드라이브가 특정 블록을 읽을 수 없기 때문에 읽기-쓰기 헤드의 위치를 변경하려는 것입니다. CD-ROM이 긁힌 CD에 대해 이 작업을 수행하는 것과 같은 이유는 특정 섹션을 읽을 수 없기 때문에 레이저 헤드의 위치를 변경하기 때문입니다.
몇 가지 SMART 값에 대해 설명하겠습니다. 100으로 정규화되었으며, 값이 낮을수록 더 나쁩니다.
7 Seek_Error_Rate 0x000f 081 060 030 Pre-fail Always - 134452477
꽤 많은 탐색 오류(80)가 발생하며 최악의 오류는 60입니다.
190 Airflow_Temperature_Cel 0x0022 054 042 045 Old_age Always In_the_past 46 (Min/Max 31/49 #21)
194 Temperature_Celsius 0x0022 046 058 000 Old_age Always - 46 (0 16 0 0 0)
과거 어느 시점에 드라이브가 너무 뜨거워져(54) 임계값(42 < 45)을 초과했습니다.
195 Hardware_ECC_Recovered 0x001a 042 027 000 Old_age Always - 209127852
드라이브에는 이미 광범위한 오류 복구가 필요합니다.
결과적으로 드라이브가 노후화되어 손상되었습니다. 드라이브를 지웠고 데이터가 필요하지 않으므로 해당 드라이브를 버리고 새 드라이브를 구입하세요. 드라이브를 계속 사용하면 일부 데이터가 확실히 손실됩니다.
