Dealing with more serious problems: -

  • After getting the faulty drive to work the first task is to recover the file system which may be damaged by using file system recovery software
  • Disk imaging has to be done in order to work from an accurate, stable hard drive image
  • The traditional disk imaging tools and methods are designed for and work on good HDDs only, not the damaged HDDs that are unstable or inaccessible because of media defects and unstable head, which are common challenges when dealing with more serious problems
  • With traditional imaging tools, the time involved is greater and the ordinary user-level repeated read access to the media bring a risk of damaging the disk and head, making lost data irretrievable
