HOW TO RECOVER DATA FROM EXTERNAL HARD DRIVES (PART 2)
This is the second series of this article click here to view previous series.
~ Clicking or Beeping Noises
Clicking sounds are often an indication of a serious hard drive damage. They occur when a hard drive is unable to return the rear/write head to its home position. The head may be stuck on a platter, scratching it violently as the disk controller attempts to move it. A scratched platter usually means an irreversible data loss.
A hard drive may make beeping sounds when it’s trying to spin the platters, but it’s unable to do so. This can happen because of something that’s known as stiction. Because the gap between the hard drive heads and platters is so small, they can literally stick to each other. A hard drive recovery service center with a well-equipped, dust-free lab should be able to solve this problem, for a hefty price.
~ Hard Drive Inaccessible
When your computer recognizes your hard drive, but you’re unable to access the files stored on it or boot into the operating system, it often means that the file system has been damaged. The damage can be extremely localized, perhaps affecting only the boot sector, or it can be widespread. The good news is that data recovery tools such as Disk Drill can easily recover data from inaccessible hard drives and help you spot growing file corruption before it gets out of hand.
~ Hard Drive Not Detected
When your computer is unable to detect a hard drive which you know is otherwise in a good working order, it could mean that the hard drive is not compatible with your motherboard. This shouldn’t happen when dealing with regular desktop hard drives connected to regular desktop computers, but it can happen when dealing with exotic server equipment or older hardware.
