    আপনি যদি হার্ডডিস্ক এর কোন অংশ পার্টিশন না করেই রেখে দেন তাহলে টা ব্যাড সেক্টর হিসেবে ধরা হয় । আপনি টা অন্য কোন ড্রাইভ এর সাথে যোগ করতে অথবা নতুন কোন ড্রাইভ খুলার জন্য এই জায়গা ব্যবহার করতে পারেন যা আপনি সহজেই কন্ট্রোল মেনু থেকে ডিস্ক ম্যানেজমেন্ট থেকে করতে পারবেন । ধন্যবাদ ।

    Bad sectors are little clusters of data on your hard disk that cannot be read. More than that, though, they are the potential to cause real damage to your hard drive (catastrophic failure) if they build up over time, stressing your read arm. Bad sectors are fairly common with normal computer use and the imperfections of the world we live in; however, there are several simple steps you can take to prevent HDD bad sectors and to repair any that you do have. Having bad sectors will not speed up computer performance as well. Here is a step-by-step guide. What is a sector, and how are HDD bad sectors created?

     

    A sector is simply a unit of information stored on your hard disk. Rather than being a soupy mass of fluid information, your hard disk stores things neatly into “sectors”. The standard sector size is 512 bytes.

    There are various problems that can cause HDD bad sectors:

    Improper shutdown of Windows;

    Defects of the hard disk, including general surface wear, pollution of the air inside the unit, or the head touching the surface of the disk;

    Other poor quality or aging hardware, including a bad processor fan, dodgy data cables, an overheated hard drive;

    Malware.

    There are two types of bad sectors – hard and soft.

    To Run Check Disk to this:

    imageFind the My Computer icon on your desktop and double-click it;

    Find the disk you want to check, right-click it and go toProperties;

    In the Properties dialog box go to Tools;

    Click Check now;

    A new dialog box will appear, check both options and clickStart;

    Most likely you will get a message that Check Disk wants exclusive access to the disk and wants to start right after your reboot. Click OK;

    Restart your computer.

     

     

     

    Preventing Bad Sector:

    You can help prevent bad sectors (always better than trying to repair them!) by paying attention to both the hardware and the software on your computer.

    Preventing bad sectors caused by hardware,,

    Make sure your computer is kept cool and dust free;

    Make sure you buy good quality hardware from respected brands;

    Always move your computer carefully;

    Keep your data cables as short as possible;

    Always shut down your computer correctly – use an uninterrupted power supply if your house is prone to blackouts.

    Use a quality disk defragmenter program with automated scheduling to help prevent head crashes (head crashes can create hard bad sectors). Disk defragmentation reduces hard drive wear and tear, thus prolonging its lifetime and preventing bad sectors;

    Run a quality anti-virus and anti-malware software and keep the programs updated.
