  3. Hard disk drive failure - Wikipedia

    en.wikipedia.org/wiki/Hard_disk_drive_failure

    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 ...

  4. Error recovery control - Wikipedia

    en.wikipedia.org/wiki/Error_recovery_control

    Modern hard drives feature an ability to recover from some read/write errors by internally remapping sectors and performing other forms of self-test and recovery. The process for this can sometimes take several seconds or (under heavy usage) minutes, during which time the drive is unresponsive.

    For example, few external drives connected via USB and FireWire correctly send S.M.A.R.T. data over those interfaces. With so many ways to connect a hard drive (SCSI, Fibre Channel, ATA, SATA, SAS, SSA, NVMe and so on), it is difficult to predict whether S.M.A.R.T. reports will function correctly in a given system.

    When a hard disk drive fails, the importance of getting the data off the drive is the top priority. The longer a faulty drive is used, the more likely further data loss is to occur. Creating an image of the drive will ensure that there is a secondary copy of the data on another device, on which it is safe to perform testing and recovery ...

    Smartmontools (S.M.A.R.T. Monitoring Tools) is a set of utility programs (smartctl and smartd) to control and monitor computer storage systems using the Self-Monitoring, Analysis and Reporting Technology (S.M.A.R.T.) system built into most modern (P)ATA, Serial ATA, SCSI/SAS and NVMe hard drives.
