  2. Personal Storage Table - Wikipedia

    en.wikipedia.org/wiki/Personal_Storage_Table

    Microsoft Outlook stores these items in a personal-storage-table (.pst) or off-line-storage-table (.ost) files that are located on the local computer. Most commonly, the .pst files are used to store archived items and the .ost files to maintain off-line availability of the items. This is an essential feature of Microsoft Outlook.

    en.wikipedia.org/wiki/Error_detection_and_correction

    The output of a cryptographic hash function, also known as a message digest, can provide strong assurances about data integrity, whether changes of the data are accidental (e.g., due to transmission errors) or maliciously introduced. Any modification to the data will likely be detected through a mismatching hash value.

    To fix this, the user should close some programs (to free swap file usage) and delete some files (normally temporary files, or other files after they have been backed up), or get a bigger hard drive. Out of memory

  5. Data corruption - Wikipedia

    en.wikipedia.org/wiki/Data_corruption

    Many errors are detected and corrected by the hard disk drives using the ECC codes [17] which are stored on disk for each sector. If the disk drive detects multiple read errors on a sector it may make a copy of the failing sector on another part of the disk, by remapping the failed sector of the disk to a spare sector without the involvement of ...

    One 64 GiB DDR5-4800 ECC 1.1 V RDIMM. Registered, or buffered, memory is not the same as ECC; the technologies perform different functions. It is usual for memory used in servers to be both registered, to allow many memory modules to be used without electrical problems, and ECC, for data integrity.

    They also automatically correct any errors detected by ECC through rewriting. The reliance on a factory servo track can complicate data recovery if it becomes unrecoverable, however. Floppy disks and tapes are poorly protected against ambient air. In warm/humid conditions, they are prone to the physical decomposition of the storage medium. [8] [7]

  8. Bush hid the facts - Wikipedia

    While "Bush hid the facts" is the sentence most commonly presented to induce the error, the bug can be triggered by other strings, for example "hhhh hhh hhh hhhhh" [2] or "this app can break", [3] and even "a "or "z!". [1] Diagram explaining the bug. The bug occurs when the string is passed to the Win32 charset detection function IsTextUnicode.

    During the POST, the BIOS must integrate multiple competing, changing, and even mutually exclusive standards and initiatives for the matrix of hardware and operating systems the PC is expected to support, although at most only simple memory tests and the setup screen are displayed.
