하드 드라이브 오류, 진단 및 수리

노트북에 하드 드라이브 오류가 발생했습니다. 500GB SATA 디스크. 그래서 디스크를 교체하고 사용자 데이터를 복구해 보아야 합니다. 디스크는 약 4년 정도 되었습니다. 디스크 손상이 얼마나 심각한지 잘 모르겠습니다. Smartcontrol 도구를 사용하여 디스크 검사를 수행했으며 디스크는 USB 포트를 통해 외부 인클로저를 통해 연결되었습니다. 결과:

Complete error log:

SMART Error Log Version: 1
ATA Error Count: 272 (device log contains only the most recent five errors)
    CR = Command Register [HEX]
    FR = Features Register [HEX]
    SC = Sector Count Register [HEX]
    SN = Sector Number Register [HEX]
    CL = Cylinder Low Register [HEX]
    CH = Cylinder High Register [HEX]
    DH = Device/Head Register [HEX]
    DC = Device Command Register [HEX]
    ER = Error register [HEX]
    ST = Status register [HEX]
Powered_Up_Time is measured from power on, and printed as
DDd+hh:mm:SS.sss where DD=days, hh=hours, mm=minutes,
SS=sec, and sss=millisec. It "wraps" after 49.710 days.

Error 272 occurred at disk power-on lifetime: 8932 hours (372 days + 4 hours)
  When the command that caused the error occurred, the device was active or idle.

  After command completion occurred, registers were:
  ER ST SC SN CL CH DH

그렇다면 문제는 다시 포맷한 후에도 이 하드 드라이브를 계속 사용할 수 있느냐는 것입니다. 손상된 것은 디스크의 데이터뿐입니까, 아니면 물리적 디스크 자체가 손상된 것입니까? 추가로 사용할 수 있다면 손상된 섹터를 복구하려면 디스크를 어떻게 포맷해야 합니까?
