  2. Device configuration overlay - Wikipedia

    en.wikipedia.org/wiki/Device_configuration_overlay

    Most major tools will remove the DCO in order to fully image a hard drive, using the DEVICE_­CONFIGURATION_­RESET command. This permanently alters the disk, unlike with the host protected area (HPA), which can be temporarily removed for a power cycle. [1]

    IDENTIFY DEVICE returns the true size of the hard drive. READ NATIVE MAX ADDRESS returns the true size of the hard drive. SET MAX ADDRESS reduces the reported size of the hard drive. READ NATIVE MAX ADDRESS returns the true size of the hard drive. An HPA has been created. IDENTIFY DEVICE returns the now fake size of the hard drive.

  4. 32-bit disk access - Wikipedia

    en.wikipedia.org/wiki/32-bit_Disk_Access

    32-bit Disk Access (also known as FastDisk) refers to a special disk access and caching mode available in older, MS-DOS-based Microsoft Windows operating systems. It was a set of protected mode device drivers that worked together to take advantage of advanced disk I/O features in the system BIOS.

    Hot-swapping a hard drive in a storage server. Hot swapping is the replacement or addition of components to a computer system without stopping, shutting down, or rebooting the system; [1] hot plugging describes the addition of components only. [2]

    On the other hand, a system in sleep mode still consumes power to keep the data in the RAM, and thus cannot last indefinitely, as hibernation can. Detaching power from a system in sleep mode results in data loss, while cutting the power of a system in hibernation has no risk; the hibernated system can resume when and if the power is restored.

  7. Sleep mode - Wikipedia

    en.wikipedia.org/wiki/Sleep_mode

    The Mac can instantaneously wake from sleep mode if power to the RAM has not been lost. However, if the power supply was interrupted, such as when removing batteries without an AC power connection, the Mac would wake from Safe Sleep instead, restoring memory contents from the hard drive. [9]

  8. Shutdown (computing) - Wikipedia

    en.wikipedia.org/wiki/Shutdown_(computing)

    To shut down or power off a computer is to remove power from a computer's main components in a controlled way. After a computer is shut down, main components such as CPUs , RAM modules and hard disk drives are powered down, although some internal components, such as an internal clock, may retain power.

  9. Hardware-based full disk encryption - Wikipedia

    Additionally, it may be possible to reboot the computer into an attacker-controlled operating system without cutting power to the drive. When a computer with a self-encrypting drive is put into sleep mode, the drive is powered down, but the encryption password is retained in memory so that the drive can be quickly resumed without requesting the ...
