How to fix or repair a Mac Hard Drive (HDD)
Suspect your Hard Disk is in need of Repair?
5 Tell-Tale Signs your Hard Disk Drive (HDD) is failing and needs replacing ASAP
1. Slowing Down Computer, Frequent Freezes, Spinning Wheel of Death (SWOD)
These are very unspecific signs that can be caused by a million different things. However, regardless of what the issue behind these symptoms is, it is recommended that you immediately make a backup and get your Computer, PC or laptop checked by The IT Guys (WA) or another suitable professional.
2. Your PC, Computer, Mac or HDD starts to make strange grinding, clicking and thrashing noises?
That could mean your drive is beyond repair. If you’re hearing strange noises then act very quickly—you probably don’t have much time.
3. Corrupted Data
You start to find files that fail to open and are corrupted even though they saved without errors or if files suddenly disappear.
4. Accumulation Of Bad Sectors
Bad sectors are areas of the hard drive that do not maintain data integrity. They are automatically masked by the operating system and thus hard to identify, especially if large amounts of the disk are currently in use. If you actually run into bad sectors, however, that certainly is a bad sign

If your Mac, Windows PC or Laptop is 5 years or older, the hard disk drive has a 50% chance of total or partial failure at any moment. We recommend replacing a HDD after 4 years.
