Failures Commonly Experienced by Hard Disk Drives:
When an external hard drive failure occurs it can fail for a variety of reasons, it is vital that the fault is diagnosed correctly by a professional data recovery specialist in order that the data on the external drive can be recovered. There are a number of signs that your hard disk drive may be close to experiencing failure, including a blue crash screen, clicking or grinding noises and a lower level of performance. If any of these symptoms are experienced, the best course of action is to turn off the computer and contact a professional data recovery service. By turning off a computer immediately upon experiencing warning signs, you’ll increase your chances that your data can be completely recovered. External Hard Drive’s can fail for a variety of reasons, below is the most common external drive failure types we receive in for data recovery:
External Hard Drive Mechanical Failure:
This type of failure is normally the result of the hard disk making beeping, buzzing or clicking noises. Beeping and buzzing noise is normally an indication that the motor has failed. A clicking noise is normally an indication that the read/write heads have failed. A clicking noise is the most common type of failure we receive in for an external hard drive. This failure is normally the result of the external hard drive getting a knock or a fall. We have a high success rate with recovering data from clicking HDD’s.
External Hard drive Electronic Failure:
This type of failure is normally the result of a power surge or power spike (a lot of cases involve connecting the wrong power supply to the external hard drive). We have a high success rate with recovering data from dead HDD’s.
Firmware is a software program that is responsible for the communication between the entire computer system and the hard disk drive. Firmware codes are typically located on data platters, and if the platter becomes damaged or corrupted, the hard disk drive will experience a failure. This type of failure occurs even if the other mechanical and electrical components of the hard drive are in perfect working order. We have a high success rate with recovering data from corrupted firmware HDD’s.
External Hard Drive is Operating very Slowly or Freezing:
This type of failure means the external hard drive is degrading. In most circumstances it means the sectors on the disk are getting corrupt and unreadable and unwritable. It can also mean that bad sectors on the hard drive are not getting allocated by the hard drive correctly. With this type of failure a client can normally not copy data from the drive or files and folders keeps appearing and then disappearing from view. We have a high success rate with recovering data from corrupted & bad sector HDD’s.
