zerofill in harddisk and bad sectors
Bad Sectors are permenent defects on a Hard Disk Drive (HDD). It maybe come from a factory defect, or an external problem. Keep the hard disk safe and away from any magnetic force or dirt and dust and you can prevent having Bad Sectors on your HDD.
No. Chkdsk may find disk errors relating to bad sectors. You want to correct these errors, locking out the bad sectors, before you defragment the disk. This is because a defrag will rearrange vast amounts of information that is on the disk, and you don't want portions of previously-readable files moved to bad sectors and be thus made unreadable.

run chkdsk to mark them bad, or use PBD(Partition Bad Disk) to isolate the bad sectors.
Most newer drives have built-in diagnostic tests known as "SMART." In your BIOS, make sure SMART monitoring is enabled. If there is a problem with your hard drive, it will display a message when you boot up. For older drives, or for computers that don't support SMART in their BIOS, the drive manufacturers usually have diagnostic tools you can download for free from their website. These can read the SMART status of the drive, as well as perform manual read/write tests.
To check for and repair bad sectors on your SD card, you can use a disk checking tool on your computer. Connect the SD card to your computer, open the disk checking tool, select the SD card, and run a scan for errors. If bad sectors are found, the tool may attempt to repair them. Keep in mind that repairing bad sectors may not always be possible, and it's recommended to back up your data before attempting any repairs.
As far as I know, the best way is to make a Low Level Format. You should find the software to perform a Low Level Format depending on the kind of your hard Disk drive. just remember it may take a long time. However, you can use an alternative program to perform a good and deep Scan Disk and fix the bad sectors. the program is called Partition magic.
Yes, you can have them. Try doing Disk Clean up and then running disk defragmenter (found in Accessories>System Tools) to help condense the areas where things are saved. If most of the drive is fragmented, then you should think seriously about backing up your documents, etc. on a disk and consider shopping for a new harddrive and/or computer.
Yes - choosing quick format does not search for bad sectors and can compromise the reliability of the disk
You can use bad sector repair software to get bad sectors repaired. Step 1: Start bad sector repair and detect software PartitionGuru and right click the disk that needs detecting bad sectors, and then select the item "Verify or repair bad sectors" Step 2: Click the button "Start Verify" on the interface bad track verification and then PartitionGuru starts to perform a surface scanning to find bad sectors. Before you get started, you can set timeout value or scanning cylinder range by entering exact value. If you are not an expert and have no ideas about these settings, you can just follow default value. Step 3:While verifying bad sectors, PartitionGuru displays detailed information of hard drive sectors. Sectors marked by red blocked means damaged, and these are bad sectors. Severe does not mean bad sector, but it is not in good condition. Step4: When scanning completes, PartitionGuru reports how many bad sectors are found. You can click "Save Report" button to save the scanning result. Step5: Click "Repair" button if you want to repair bad sectors on the "Bad Track Verification" window. Step 6: You'll receive a warning that asks to back up data first. If you have created a backup for important data, click "OK" button. If not, click "Cancel" and backup your files. Step 7: Another warning message from PartitionGuru, which tells repairing bad sectors does not equal to recovering files and you should recover data first. Click "OK" if file recovery is not needed. If you want to recover data, you should click "Cancel" and use "File Recovery" function to scan the disk to find lost data. Step 8: When the repairing process complete you'll receive following message. Click "OK" button and close the software.
Well, honey, when disk controllers remap bad sectors, they basically say "adios" to those problematic areas and assign them to spare sectors. This can improve data retrieval rates because the system won't waste time trying to read from those faulty sectors. So, in a nutshell, it's like getting rid of the dead weight to keep things running smoothly.
