A cyclical repetitive pattern of seek activity such as rapid or slower seek-to-end noises ( click of death) can be indicative of hard drive problems. A rising number of bad sectors can be a sign of a failing hard drive, but because the hard drive automatically adds them to its own growth defect table, they may not become evident to utilities such as ScanDisk unless the utility can catch them before the hard drive's defect management system does, or the backup sectors held in reserve by the internal hard-drive defect management system run out (by which point the drive is on the point of failing outright).

Gradual hard-drive failure can be harder to diagnose, because its symptoms, such as corrupted data and slowing down of the PC (caused by gradually failing areas of the hard drive requiring repeated read attempts before successful access), can be caused by many other computer issues, such as malware. The former typically presents as a drive that can no longer be detected by CMOS setup, or that fails to pass BIOS POST so that the operating system never sees it. If either the drive or the media is dirty, users may experience the buzz of death when attempting to access the drive.įailure of a hard disk drive can be catastrophic or gradual. 3.5-inch floppy disks can also fall victim to disk failure.

In the late 1990s, Iomega's 100-megabyte Zip disks used in Zip drives were affected by the click of death, called so because the drives endlessly clicked when accessed, indicating the impending failure. The phenomenon of disk failure is not limited only to drives, but also applies to other types of magnetic media.
The most notorious cause of drive failure is a head crash, where the internal read-and-write head of the device, usually just hovering above the surface, touches a platter, or scratches the magnetic data-storage surface. On the other hand, a drive can fail at any time in many different situations. Therefore, even if a drive is subjected to several years of heavy daily use, it may not show any notable signs of wear unless closely inspected. If a drive proves reliable for a period of a few months after installation, the drive has a significantly greater chance of remaining reliable. Drives typically fail within a short time if there is a defect present from manufacturing. Hard disk drive failures tend to follow the concept of the bathtub curve. These are calculated by constantly running samples of the drive for a short period of time, analyzing the resultant wear and tear upon the physical components of the drive, and extrapolating to provide a reasonable estimate of its lifespan.
Drive manufacturers typically specify a mean time between failures (MTBF) or an annualized failure rate (AFR) which are population statistics that can't predict the behavior of an individual unit. There are a number of causes for hard drives to fail including: human error, hardware failure, firmware corruption, media damage, heat, water damage, power issues and mishaps.
