TOOLS TO DO TROUBLESHOOTING IN PREVENTIVE MAINTENANCE, 1.CHKDSK admin…

- - - - File recovery software is a type of software that enables the recovery of corrupted, deleted or inaccessible data from a storage device.
        
        This software reviews, scans, identifies, extracts and copies data from deleted, corrupted and formatted sectors or in a user-defined location within the storage device.
        
        File recovery software generally has access to the core architecture of a hard disk. It can extract data from corrupt storage devices or deleted files/folders by referring and accessing the file structure records/entries. Having access and control over file systems and structure, it can also un-format and repair hard drive partitions.
        
        It can be used for both recovering user-stored and system-created data, files and folders. It can recover data from virtually any storage device including hard disks, flash drives, external storage cards, tape drives and more. Most data recovery software can perform data recovery on common file systems.
- - - - Formatting has 3 steps :
      - First insert the OS drive in the computer through external devices or through CD or DVDs.
      - Second, one may go to the drive where the OS is there and go to the repair area for a disk check and repairing the thing that is in wrong condition or restore a string which has been missing
- - - - WHAT IS EXTERNAL ENCLOSURE
        In small business and home use, external drive enclosures can be useful for data recovery. Many times when a hard drive fails and the data it contains seems to be inaccessible, it is actually the electronics or connection points in the external drive enclosure that no longer work properly.
    - - Drive enclosures provide power to the drives therein and convert the data sent across their native data bus into a format usable by an external connection on the computer to which it is connected. In some cases, the conversion is as trivial as carrying a signal between different connector types.
    - - Increased storage capacity: External enclosures allow you to add extra storage capacity to your computer without having to replace your existing hard drive or SSD. This is particularly useful if you have a laptop with limited storage capacity.
      - Backup storage: External enclosures can be used as backup storage, allowing you to store important files and documents in a separate location to protect against data loss in the event of a computer failure.
      - Portability: Some external enclosures are small and lightweight, making them easy to transport. This can be useful if you need to transfer data between computers while on the go.
      - Cost-effective: External enclosures are often less expensive than purchasing a new hard drive or SSD. They also allow you to reuse an existing drive that may no longer be needed in its original computer.
      - Easy data transfer: External enclosures allow you to transfer data between computers easily. You can simply remove the drive from one computer and insert it into the enclosure, then connect the enclosure to the other computer.
    - - Limited performance: External enclosures typically have lower performance compared to internal hard drives or SSDs. This is because the data has to travel through the interface controller before it can be accessed by the computer. This can result in slower transfer speeds and longer access times.
      - Connectivity issues: Depending on the type of interface used by the external enclosure, you may experience connectivity issues. For example, some older enclosures may use a USB 2.0 interface, which can be much slower than newer USB 3.0 or Thunderbolt interfaces.
      - Compatibility issues: Not all hard drives or SSDs will be compatible with all external enclosures. Some enclosures may only work with certain types of drives or may not work with newer drives that use advanced formatting techniques.
      - Security concerns: If you are using an external enclosure to store sensitive data, you need to take steps to ensure that the data is properly secured. External enclosures can be lost or stolen, which could potentially expose your data to unauthorized access.
      - Power limitations: Some external enclosures may not provide enough power to run certain hard drives or SSDs. In these cases, you may need to purchase an external power adapter or choose a different enclosure that can provide the necessary power.
    - - Some external enclosures support multiple drives, allowing you to combine several hard drives or SSDs into a single logical volume for increased storage capacity or improved performance.
      - External enclosures can be connected to your computer using a variety of interfaces, including USB, FireWire, Thunderbolt, eSATA, and Ethernet.
      - Some external enclosures include built-in hardware encryption, which can provide an added layer of security for your data.
      - External enclosures can be used for a variety of purposes beyond storage, including connecting other peripherals, such as printers or scanners, to your computer.
      - External enclosures are available in a wide range of sizes, shapes, and designs, from small, portable enclosures designed for use with laptops to large, desktop-style enclosures designed for use with desktop computers.
      - External enclosures can be used for both Windows and Mac computers, making them a versatile solution for storing and transferring data between different types of systems.
