    Study Notes

    • A "cannot read from the source disk" message indicates problems with storage drive reading or writing information.
    • This could mean the drive has failed or is experiencing slow response with constant LED access activity.
    • If the drive is making loud clicking noises, it may be the "click of death" signaling imminent failure.
    • To troubleshoot, make a backup of critical data, check loose or damaged cables, and ensure adequate power.
    • Overheating, recent hardware additions, and power supply issues can also cause storage problems.
    • Boot issues like "drive not recognized" or "operating system not found" can be caused by physical configuration, BIOS settings, or USB devices.
    • RAID (Redundant Array of Independent Disks) is a common method to maintain data availability and redundancy, but can also have issues.
    • SMART (Self-Monitoring, Analysis, and Reporting Technology) is a standard for monitoring storage drive performance and health.
    • Peak performance in storage devices can be affected by various factors, including memory access, bus communication, and physical drive operation.
    • IOPS (Input/Output Operations Per Second) is a measurement of storage device performance for reading and writing data.
    • A failing drive should be backed up and replaced as soon as possible.
    • Hard drives are mechanically complex systems and will eventually fail; solid state drives can also fail.
    • RAID arrays require multiple drives, and specific RAID types have different failure scenarios and requirements.
    • SMART information can provide diagnostic details on drive health and performance, and third-party utilities or operating systems can monitor this data.
    • Mini RAID arrays offer diagnostics and performance checks, and can alert users of potential issues.
    • Drive diagnostics, like IOPS measurements, can help determine overall storage device performance.
    • A failing drive may display symptoms like slow response, constant access activity, loud noises, or boot issues.
