A hard disk drive failure occurs when a hard disk drive malfunctions and the stored information cannot be accessed with a properly configured computer. A hard disk failure may occur in the course of normal operation, or due to an external factor such as exposure to fire or water or high magnetic fields , or suffering a sharp impact or ...
Hard disk and other storage drives are subject to failures (see hard disk drive failure) which can be classified into two basic classes: Predictable failures which result from slow processes such as mechanical wear and gradual degradation of storage surfaces. Monitoring can determine when such failures are becoming more likely.
A head crash in a modern drive. Note circular scratch mark on the platter. A head crash. A head crash is a hard-disk failure that occurs when a read–write head of a hard disk drive makes contact with its rotating platter, slashing its surface and permanently damaging its magnetic media. It is most often caused by a sudden severe motion of the ...
The most common data recovery scenarios involve an operating system failure, malfunction of a storage device, logical failure of storage devices, accidental damage or deletion, etc. (typically, on a single-drive, single-partition, single-OS system), in which case the ultimate goal is simply to copy all important files from the damaged media to another new drive.
On a hard disk drive, the click of death refers to a similar failure mode; the head actuator may click or knock as the drive repetitively tries to recover from one or more errors. These sounds can be heard as the heads load or unload, or they can be the sounds of the actuator striking a stop, or both.

S.M.A.R.T. software warning suggests impending hard drive failure. Distinct types of data storage have different points of failure and various methods of predictive failure analysis. Vulnerabilities that can instantly lead to total loss are head crashing on mechanical hard drives and failure of electronic components on flash storage.
The computer technician can only reimage if there is an image of the hard drive for that computer either in a separate partition or stored elsewhere. [ 3 ] On a Microsoft Windows system, if there is a restore point that was saved (normally saved on the hard drive of the computer) then the installed applications and Windows Registry can be ...
