This article will illustrate you what Reallocated Sector Count is and how to get rid of it with Reallocated Sector Count warning fixes.

S.M.A.R.T. (Self-Monitoring, Analysis and Reporting Technology) is a monitoring system included in computer hard disk drives (HDDs), which can monitor the health status of your hard drive.

If the S.M.A.R.T status information shows Caution, and the value of Reallocated Sector Count attribute is increasing consistently, you should keep an eye on your hard drive and the data stored on it.

What on earth the Reallocated Sector Count attribute is? What does Reallocated Sector Count mean? If you want to know more information about the Reallocated Sector Count and how to fix it, you may read the following contents.

What Does Reallocated Sector Count Mean

Reallocated sector count is a critical S.M.A.R.T. attribute, which indicates the count of reallocated sectors on your hard drive. Well, what does the reallocated sector mean? Now, let me explain it to you.

When a read or write error emerges on your hard drive, your drive marks this sector as “reallocated”. And then it transfers data to a special reserved area which called spare area. In other word, the reallocated sectors are bad sectors on your hard drive that have been moved to another part of the disk.

This is also the process called remapping and “reallocated” sectors are called remaps. In this way, you will not see bad sectors when making surface test, but bad sectors do exist which are hidden in reallocated sectors.

When there are more sectors reallocated, the read/write speed will decrease significantly. If S.M.A.R.T data for your hard drive shows a number above 0 next to the attribute Reallocated Sector Count, you need to pay attention to it. The increasing reallocated sectors are a sign of hard drive failure.

Once the hard drive is failed, all your data stored on the hard drive will get lost. In this case, when you find the Reallocated Sector Count warning appears, the first thing is to make a backup immediately.

Backup Hard Drive Immediately

To avoid data loss caused by hard drive failure, you should back up your hard drive as soon as possible.

If you have an SSD or HDD with the Allocated Sector Count warning sign, and that number of the allocated sectors keeps going up, backup hard drives with the above tutorial and then replace it.

How to Fix Reallocated Sector Count Warning

Then you may wonder: is there any Reallocated Sector Count fixes recommended? Can the reallocated sectors be fixed?

Unfortunately, this can’t be fixed and there is no Reallocated Sector Count fix software. If the number of the allocated sector continues to go up, you’d better purchase a new hard drive.

If your hard drive is still under warranty, you can contact the manufacturer for a replacement.

However, there is no way to reduce the reallocated sectors on your hard drive. You can keep using the hard drive, but don’t keep important data stored on the drive.

Similarly, there are some other S.M.A.R.T parameters you need to pay attention to, especially when it gives you a caution warning.

  • Current Pending Sector Count: the current count of unstable sectors on your disk that are waiting to be reallocated to spare drive space.
  • Reallocation Event Count: a count of the attempts to transfer data from a bad sector to a special reserved area (spare area).
  • Uncorrectable Sector Count: the total number of uncorrectable errors when reading/writing a sector.

Of course, there are other hard drive utilities that can help you check S.M.A.R.T. information and these parameters. Be sure to choose a reliable one.
