We have specialized file utilities designed for virtually every file system and file type, and as a result, we offer high success rates for external hard drives. ![]() Secure Data Recovery thrives on challenges in data recovery, 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. ![]() All physically damaged external drives need to be treated in our certified Class 10 ISO 4 Cleanroom to prevent any danger of media contamination. Failure Scenarios - As mentioned above, the type of failure scenario affects the chances of recovery, and therefore the recovery tools and procedure that are needed.Our engineers create full clones of repaired external hard drives before using our proprietary software, to recover the data without damage to the external drive. Hard Drive Size - Some newer external hard drives hold 8TB of data or more, and data recovery is often difficult on larger drives.Our engineers work with all operating systems on external hard drives including Windows, Mac, and Linux. File System - Depending on the operating system used, an external hard drive can be formatted in different file systems including FAT, NTFS, HFS+, EFS and XFS.Some of the factors that can affect your chances of successful data recovery on an external hard drive include: The Challenges of External Hard Drive Data Recovery Power surge, preventing your hard drive from being disconnected properlyĮxternal hard drives can also lose data due to non-physical errors that affect how the drive operates.Power cords not plugged into grounded, surge-protected outlets.Some external hard drives experience electronic failure due to: Electronic failures are potentially as serious as physical hard drive failures and should only be handled by experienced data recovery professionals. 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. Grinding, clicking, or beeping noises on the drive due to read/write head failures.Spindle that controls hard drive spinning locks up.In addition to internal wearing out and scratching the platters, other common physical failures include: A hard drive's read/write heads hover just above the surface of the platters that store your data, and if they come into contact with the platters, data loss may occur. ![]() Hard drives have internal parts moving at high speeds and they can become less reliable as they age. There are three basic types of external hard drive failure that can result in data loss:
