I bought my hp pavillion-15 n204tx laptop an year ago. It was very fast and snappy when it was new but the performance started to gradually degrade since a few of months. I thought it must be because of some virus and temporary junk files. I did a fresh windows install but the problem persisted. While browsing throught various forums on internet i came across various softwares which displays and analyses the SMART data of the hard-disk drive. All of them unanimously deemed my hard-disk to be in bad health and showed the reason to be the 'Rellocated sectors count'. The raw value was 000000000538 and the normalised value was 92. Is the hard-disk the real problem? Does the hard-disk need to be replaced?

The 'Rellocated sectors count' is the number of bad sectors which seems extremely high since it is displayed in HEX. This would equate to 1336 bad sectors.

When using the software Speccy, it will give you a Real Value on the amount of the sector.

use the hard drive manufacturer diagnostic software to test the drive.

Hi there Nitish55,

After your drive has some bad sectors related issues, you need to back up the data that is stored on it as soon as possible. Then, you should test the drive with a brand specific testing tool as Emerald already suggested. If you get similar results, my advice would be to get another drive and use this one for storing non important data. Bad sectors will eventually continue to appear. :(
Some users write zeros on such drives(you should back up all the data first). It could slow down the dying process.
If the laptop is under warranty, it may be a good idea to contact the manufacturer's Support.

Cheers,
