HARD DISK INFORMATION


HARD DISK INFORMATION OF POST


HARD DISK DURING POST(power-on-self-test):

    process, your computer's BIOS checks various hardware components, including the hard disk. If the hard disk is detected and operational, the BIOS proceeds to load the operating system. If there's an issue with the hard disk, the BIOS may display an error message or fail to boot the system.                                                                                                                                                                                                                                         TYPES OFHARD DISK

It is a secondary storage device used to store data permanently, random access memory (RAM) being the primary memory device.A hard disk drive is also known as a hard drive                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                            



                                                                                                                                                                                                                               

Hard disk drive storage capacity

  • 16 GB, 32 GB and 64 GB. This range is among the lowest for HDD storage space and is typically found in older and smaller devices.
  • 120 GB and 256 GB. This range is generally considered an entry point for HDD devices such as laptops or computers

        500 GB, 1 TB and 2 TB. Around 500 GB and above of HDD storage is typically considered decent for an average user. Users can most likely store all their music, photos, videos and other files with this much space. Individuals with games that take up a lot of space should find 1 TB to 2 TB of HDD space suitable                            

Common hard disk errors

Hard disks can fail for all sorts of reasons. However, failures generally fall into the following six broad categories.

  • Electrical failure occurs when, for example, a power surge damages a hard disk's electronic circuitry, causing the read/write head or circuit board to fail. If a hard disk powers on but cannot read and write data or boot, it is likely that one or more of its components has suffered an electrical failure.
  • Mechanical failure can be caused by wear and tear, as well as by a hard impact, like a hard drop. This may cause, among other things, the read/write drive head to hit a rotating platter, causing irreversible physical damage.
  • Logical failure results when the hard disk's software is compromised or ceases to run properly. All sorts of data corruption can lead to a logical failure. This includes corrupted files, malware and viruses, improperly closing an application or shutting down a computer, human error or accidentally deleting files that are critical to hard disk functionality.
  • Bad sector failure can occur when the magnetic media on a hard disk's rotating platter is misaligned, resulting in a specific area on the platter becoming inaccessible. Bad sectors are common and often limited when they occur. Over time, however, the number of bad sectors can increase, eventually leading to a system crash, inaccessible files or the hanging or lagging of the operation of a hard disk.
  • Firmware failure happens when the software that performs the maintenance tasks on a drive and enables the hard disk to communicate with a computer becomes corrupted or stops working properly. This type of failure can lead to the disk freezing during bootup or the computer a hard disk is connected to not recognizing or misidentifying it.
  • Multiple unknown failures that accumulate over time can also occur. For example, an electrical problem could lead to a mechanical failure, such as a read/write head crash. It might also lead to a logical failure, resulting in several bad sectors developing on the hard disk platters.

          








  6. In the System Information window, click the + symbol next to Components. Click the + next to Storage and click Drives. In the right-side of the window, you see information about the hard drive including its capacity and serial number.

  7. A hard drive or hard disk drive (HDD) is a type of data storage device that is used in laptops and desktop computers. An HDD is a “non-volatile” storage drive, which means it can retain the stored data even when no power is supplied to the device

    2. >BIOS/UEFI Screen: When you first power on your computer, you might see a splash screen displaying the logo of your computer's manufacturer or the motherboard manufacturer. On this screen, there is often a prompt or key combination (like "Press [Key] to Enter Setup" or "Press [Key] for UEFI/BIOS") that allows you to access the BIOS/UEFI settings. Once you enter the BIOS/UEFI, you can navigate through the menus to find information about your hard disk drives.


    4. >Boot Device Selection Screen: Some systems might display a menu during POST that allows you to select a boot device. This menu typically lists all the available storage devices (including hard drives) from which you can boot. It might also show relevant information like the device name, capacity, and sometimes the model number.

      1. >System Information or Hardware Status Page: Within the BIOS/UEFI settings, there's often a section or page dedicated to system information or hardware status. Here, you can find detailed information about various hardware components, including hard drives. This information might include the hard drive's manufacturer, model, capacity, and sometimes its SMART (Self-Monitoring, Analysis, and Reporting Technology) status.


      3. >Error Messages and Codes: If there's an issue with the hard disk detected during the POST process, your computer might display an error message or a numeric error code on the screen. These messages can provide clues about what might be wrong with the hard drive and can help in troubleshooting.


      5. >Diagnostic Tools: Some BIOS/UEFI interfaces include built-in diagnostic tools or tests that can check the health and status of connected hard drives. These tools might provide more detailed information about the hard drive's condition.


      7. >External Display: If your computer has an external display or an integrated diagnostic panel (such as on certain server systems), hard disk information might be displayed there along with other system status details.

      Remember that the exact steps and locations can vary depending on your specific hardware and BIOS/UEFI version. If you're specifically looking for hard disk information during the POST process, start by accessing your system's BIOS/UEFI settings and navigating through the available menus and options. If you encounter any error messages or issues, these can also provide valuable information about the state of your hard drives
