What is HDD? How to fix bad hard disk.

                       HDD stands for hard disk drive. It is a type of storage device that is used to store and retrieve digital information using rapidly rotating disks / platters coated with magnetic material. HDDs are commonly used in computers and other electronic devices to store large amounts of data, such as documents, music, and videos. There are two types of HDD or SSD. HDDs are an older technology compared to solid-state drives (SSDs), which use memory chips instead of spinning disks to store data. SSDs are generally faster and more reliable than HDDs, but they are also more expensive. Some newer computers come with both an HDD and an SSD, with the SSD being used for faster access to frequently used files and the HDD being used for less frequently accessed data.

How to fix bad hard disk:-

                       There are several ways you can try to fix a bad hard disk:-

1) Run disk check:- You can run disk check to scan and fix errors on the hard disk. To do this, right-click on the hard disk and select "Properties." Under the "Tools" tab, click "Check" to run disk check.

2) Run disk cleanup:- Disk cleanup is a built-in tool in Windows that can help free up space on your hard disk by deleting temporary files and other unnecessary items. To run disk cleanup, type "disk cleanup" in the search bar and click on the "Disk Cleanup" app that appears.


3) Check for bad sectors:- Bad sectors on a hard disk can cause errors and prevent data from being saved or accessed. You can use a tool like chkdsk to check for and repair bad sectors on your hard disk.

4) Rebuild the MBR:- The MBR (Master Boot Record) is a critical component of your hard disk that helps the computer boot up. If the MBR is damaged, you may experience errors or problems starting your computer. You can use a tool like bootrec to rebuild the MBR and fix any boot-related issues.

5) Replace the hard disk:- If none of the above solutions work, it may be necessary to replace the hard disk. This is a more advanced and potentially risky procedure, so it is recommended to seek the assistance of a professional if you are not comfortable doing it yourself.
