Over the years, hard disks have become more reliable and offer larger storage capacities to meet the needs of advanced operating systems and applications. However, despite these improvements, hard disks can still fail due to various factors. Whether it’s from external causes like lightning strikes, power surges, or even simple human errors, data loss can occur, leaving your files inaccessible.

Data loss can be caused by both logical and physical issues. Logical problems include knocking, bad sectors, wrong capacity, password locks, or when the hard drive is not detected or recognized by BIOS. Physical problems are more severe and involve issues like burned PCBs, water or fire damage, a dropped disk, head crashes, or power surges. At Annai Systems, we specialize in data recovery services, and we have successfully recovered data from hard disks that were previously thought to be beyond repair.
