HDD Bad Sector

Hi Nataniel!

I am not sure what your question is exactly, but one thing I'd recommend for sure will be to look for a replacement drive since there is already a bad sector on your current one.

Basically there are two kinds of bad sectors - hardware and software:

• Hardware ones are caused by physical damage or becoming magnetically fixed, and they are unrepairable. In short, once they appear it's only a matter of time (no way to say how long) until the HDD fails.
• Software bad sectors on the other hand occur when something called an Error Correction Code (ECC) doesn't match the contents of the hard drive. These can be repaired by overwriting the data on the drive with zeroes (a.k.a. low level formatting) and sometimes
  by running a **chkdsk [write the letter of the drive:] /r** in the CMD.

As for getting the information from the drive if one of the partitions fail, most likely you won't be able to, which is why I'd suggest to make a regular backup of your most important data.

Hope this helps and feel free to ask any questions you may have.

 

Bad sectors

There are two types of 'bad sector:'

A physical bad sector is bad because of some physical defect. It's not uncommon for a hard drive to have a few of these. Windows simply marks them as 'bad' so they won't be used for storage. You only need to worry if bad sectors begin to proliferate.

A logical bad sector is bad because of a software problem, e.g., Windows can't find it or its description has contradictory information. Running CHKDSK will usually fix that, but again, it's not uncommon and only a problem if Windows
tells you it's a problem.

All modern hard drives ship with a utility called S.M.A.R.T. whose purpose is to monitor the drive for problems and notify the user before problems become serious. If you're not getting a notification from S.M.A.R.T. and you're not receiving error messages
from Windows, you've got nothing to worry about.

If you still think there's a problem, then run the hard drive manufacturer's own drive diagnostic utility. You can download it from the manufacturer's website, and the manufacturer will show you how to interpret the results.

If you're determined to replace your hard drive, then I guess you'll do it anyway. But why go to the trouble if you don't really need to?

 

hard disk bad sector repair in Windows 10

Hi Mohqasim,

Before proceeding further, please answer few queries.

1. What is the make, and model of the Computer?

2. What is the complete error message/code you receive?

As per the description, I understand that there could be some bad sector in the hard disk.

Meanwhile, I would suggest you to follow the below steps to run the check disk, and check.

1. Press Windows + X, select Command prompt(Admin).

2. Type the following command, and hit Enter.

chkdsk /r/f

Disclaimer: While performing check disk on the hard drive if any bad sectors are found on the hard drive, then chkdsk tries to repair that sector if any data available on that might be lost.

Please let us know if the issue got fixed or you need any further assistance.

Thank you.
