[2023 Updated] Common reasons why hard disks fail

Published on 11-28-2023  | 

Most common reasons for hard disk failure:

  1. Human Error: The most common cause, including accidental file deletion or physical mishandling of the hard disk.
  2. Disk Hardware Failure: Involving physical damage often due to head crashes, which occur when the read/write heads touch or gouge the disk's surfaces, causing permanent data loss. Additional failures can occur in the drive's controller board.
  3. Firmware Corruption: Issues with the drive's firmware can render a disk unreadable, leading to data loss. Notable examples include the BSY problem in Seagate drives.
  4. Heat: Excessive heat can cause disk platters to expand and contract, resulting in micro cracks on the magnetic surface and data loss.
  5. Water Damage: Liquids can cause electrical surges that severely damage the hard drive.
  6. Power Issues: Power surges from various sources can disrupt the function of read/write heads and potentially lead to data loss.Возможно, это изображение текст
