External Hdd Datarecovery
Since the early 2000s, computer owners have used external hard drives as a quick secondary form of storage and as a reliable method of data backup. External hard drives typically consist of a standard 2.5" or 3.5" hard drive in a simple enclosure with an external port that connects to a desktop or laptop computer (usually via USB).
At Data Recovery Services, we handle hundreds of external HDD recovery and repair cases each year, including drives from brands like Seagate, Maxtor, Fujitsu, Western Digital, Iomega, Dell, IBM and more. Our engineers are familiar with the various factors that can affect the recovery process on these devices.
When an external hard drive fails, you need to work with a qualified company that understands the potential challenges of external HDD data recovery. Dozens of companies manufacture the devices, however, so many have unique features that can complicate professional data recovery services.
Reasons for External Hard Drive Data Loss
Physical Failures - Because hard drives have high-speed moving parts, they can become less reliable as they age. A hard drive's read/write float just above the surface of the platters, which store your data, and under the right circumstances, the heads might come into contact with the platters. This is often accompanied by a clicking or whirring sound, but users may not hear these sounds if their external hard drives have large or well-insulated enclosures.
Electronic Failures - Some external hard drives have faulty fans, or computer users simply forget to plug their power cords into grounded, surge-protected outlets. If an external hard drive has an electronic issue, it may stop working entirely or it may report an error message, depending on which of its components have failed.
Logical Failures - External hard drives can also lose data due to corruption, accidental deletion or other non-physical errors, which are considered logical errors in our classification system.
