Hard Disk Failure Signs.

• Your computer “freezes” too often (the picture on the screen is still and does not react to mouse or keyboard manipulations)

• Regular booting problems. That may be a sign of bad sectors on the disk with corrupted booting data.

• You computer is terribly slow while accessing, saving and opening files.

• The usual sound produced by your hard drive is louder than before

• Regular appearance of BSOD (Blue Screen of Death), “Operating system not found or Missing Operating System” or “your hard drive is not formatted” messages at startup.

• Your computer is still running normally, but you can hear unusual metallic sounds (grinding, clicking, whirring, scratching, buzzing). That’s a very bad sign that may imply mechanical damage.

• You cannot hear any hard drive sounds at all. When the information is written to or read from the disk, it spins and produces sounds, you must be accustomed to these normal sounds. As an example, hard drive becomes silent when it’s inside components expand and get stuck because of overheating.

• Your hard drive is clicking or producing grinding metallic sounds, your computer won’t recognize the hard disk. This is a sign that hard drive failure have happened.
