    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.

  3. Hot swapping - Wikipedia

    en.wikipedia.org/wiki/Hot_swapping

    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]

  4. Hibernation (computing) - Wikipedia

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

    Hibernation is a means of avoiding the burden of saving unsaved data before shutting down and restoring all running programs and re-opening documents and browser tabs. Both hibernation and sleep preserve memory fragmentation and atrophy that lead to mobile devices working poorer the longer they run without a full reboot.

    A 3.5-inch Serial ATA hard disk drive A 2.5-inch Serial ATA solid-state drive. SATA was announced in 2000 [4] [5] in order to provide several advantages over the earlier PATA interface such as reduced cable size and cost (seven conductors instead of 40 or 80), native hot swapping, faster data transfer through higher signaling rates, and more efficient transfer through an (optional) I/O queuing ...

  6. DevSlp - Wikipedia

    en.wikipedia.org/wiki/DevSlp

    DevSlp or DevSleep (sometimes referred to as device sleep or SATA DEVSLP) is a feature in some SATA devices which allows them to go into a low power "device sleep" mode when sent the appropriate signal, which uses one or two orders of magnitude less power than a traditional idle (about 5 mW, [1] but some drives can get as low as 2.5 mW [2]).

    Two 2.5" external USB hard drives Seagate Hard Drive with a controller board to convert SATA to USB, FireWire, and eSATA Current external hard disk drives typically connect via USB-C; earlier models use USB-B (sometimes with using of a pair of ports for better bandwidth) or (rarely) eSATA connection. Variants using USB 2.0 interface generally ...

    Within a standard hard drive form factor case the encryptor (BC), key store and a smaller form factor, commercially available, hard disk drive is enclosed. The enclosed hard disk drive's case can be tamper-evident, so when inspected the user can be assured that the data has not been compromised. The encryptors electronics including the key ...

    The software then tells the hard disk drive to unload its heads to prevent them from coming in contact with the platters, thus potentially preventing a head crash. [1] Many laptop vendors have implemented this technology under different names. [2] Some hard-disk drives also include this technology, needing no cooperation from the system. [3]
