Six Signs You Should be Worried About Your Hard Drive’s Health

Slow folders and files

Most people complain about their computer being slow at some point. If you notice a real slowdown in disk transfer speed when opening files, your hard drive health may be low.

Corrupted files

Error messages about corrupted or unavailable files indicate a failing drive. When this occurs, it’s crucial to act before all data becomes irretrievable.

Bad sectors

The blue screen of death

Experiencing the blue screen of death is often a sign of a failing disk. Although it may be a random computer issue, blue screens frequently precede hard disk failures.

New weird sounds

Unusual noises from your disk drive, such as clicking or screeching, should raise concerns. These sounds might signal that your storage device is on the brink of failure.

Hard Drive Failure Could Cost You

Productive time

If your hard drive crashes, then you’ll lose time. You might lose a working day when you discover the crash. Then there will be more time lost trying to figure out what to do.

Data recovery

The average cost of data recovery from a hard drive could be a few hundred dollars. Data loss for businesses could easily cost thousands more. If you have valuable files or a sentimental photo collection, this might be worth it. But why pay the price?
