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.
For instance, many newer hard drives are designed specifically for backup and come with software that automatically copies the user's selected files to the external drive on a set schedule. Other external hard drives have setup disks that allow users to choose from several formatting options, including RAID options if the external enclosure contains two or more internal HDDs.
Reasons for External Hard Drive Data Loss
There are three basic types of external hard drive failure that can result in 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.
The platters of a hard drive also spin, and the spindle that controls this action can lock up, preventing the drive from reading properly. Hard drives can also have problems with the actuator arms that hold the read/write heads, and due to the extreme precision of modern HDD technology, even a slight error can completely prevent a computer user from accessing any data.
At Secure Data Recovery Services, we treat all physical data recovery issues in certified Class 10 ISO 4 Clean room, which is a specialized environment that prevents particles from coming into contact with your external HDD. By working in Cleanroom, we can repair physical damage without any risk to your media.
- 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.
Electronic failures are potentially as serious as physical hard drive failures and should only be handled by experienced data recovery professionals.
- 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.
Recoverability varies greatly for logically damaged external hard drives. If you notice missing files or you see data corruption messages that might indicate a logical error, immediately shut down your external hard drive to avoid overwriting your data.
Free Evaluations for Portable Hard Drive Data Recovery
Regardless of your hard drive's failure scenario, our engineers will take a measured, planned approach to evaluate the failure. We will provide you with a free media diagnostic report before starting our work on your case. You can view your external hard drive's chances of recovery, a list of recoverable files, a likely case completion time frame and an accurate price quote. We offer free diagnoses through our network of more than 30 locations across the United States.
In addition to our external and portable hard drive recovery services, we offer repair and recovery for other external devices including micro drives, USB drives and flash cards. Call us for more information about any of our services or to schedule a media diagnosis.
The Challenges of External Hard Drive Data Recovery
Some of the factors that can affect your chances of a successful data recovery on an external hard drive include:
- File System - Depending on the operating system you use on your computer, you may have formatted your external hard drive in a number of different file systems, including FAT, NTFS, HFS+, EFS and XFS. Our engineers have extensive experience with all of these file systems and with various operating environments such as Windows, Mac OS, Linux and Unix.
We have specialized file utilities designed for virtually every file system and file type, and as a result, we offer high success rates across-the-board for external hard drives.
- Hard Drive Size - Some newer external hard drives hold 2TB of data or more, and data recovery is often difficult on larger drives. Our engineers use a careful approach and always create full clones of repaired external hard drives before using our proprietary software, and we can recover hard drives of all sizes without risking media damage.
We also have capable physical recovery tools for all physical hard drive sizes, including standard 3.5" desktop drives, 2.5" laptop drives and 1" micro drives.
- Failure Symptoms - As mentioned above, failure scenario affects the chances of recovery. All physically damaged external drives need to be treated in a Certified Class 10 ISO 4 Cleanroom to prevent any danger of media contamination.
Secure Data Recovery Services also uses experienced engineering teams to treat each case, so whether your external drive has logical data issues or a severe spindle failure, we have the capabilities, experience and tools to give you the best possible chances of a successful recovery.
