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 ...
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.
Many motherboards display a warning message upon boot when a disk drive is approaching failure. Although an industry standard exists among most major hard drive manufacturers, [8] issues remain due to attributes intentionally left undocumented to the public in order to differentiate models between manufacturers.
A WDTLER.EXE utility allows the enabling or disabling of the TLER parameter on Western Digital hard drives. This utility is written for DOS. The utility works on and makes changes to all compatible Western Digital hard disk drives connected to the computer. The change survives power-cycling. Western Digital used to mention the tool in an FAQ. [12]
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.
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 ...

Hard disks and larger removable media such as Zip drives made the need to manage multiple disks per drive obsolete, and thus made the prompt useless. It was gradually replaced with code that acted like "Fail" immediately. DOS 3.3 COMMAND.COM provided the startup option /F to
