• Any generation: old or new
• Any operating system (Windows, Linux, macOS, etc.)
• Every kind of data loss: from simple to complex; fire or water damage, malware/ransomware,
  accidental deletion, file corruption, system crashes, hardware failure, etc.

Warning signs and sounds that may indicate impending HDD failure/data loss:

• Strange, unusual noises or scratching/grinding sounds
• “Blue Screen of Death” (BSOD)
• Bad sectors
• Slow response, slow copying, freezes or stalls during copy
• Operating system starts slowly or with difficulty
• SMART warning at boot

What to do if you notice a failure?

• Power off the computer (or external drive) immediately or disconnect power. Further operation can damage the hard drive (sometimes multiple drives) and greatly reduce the chances of a successful recovery.
• Do not restart the computer or external drive!
• Do not attempt a reinstall or start a repair from an installer disc/USB!
• Do not shake or disassemble a suspected-damaged drive; untrained handling can cause more harm!
• Do not experiment with recovery utilities on the damaged files!
• Never operate a visibly damaged device!
