![]() The Byte-to-byte Backup feature in Disk Drill creates a byte-level copy of your disk, i.e., a disk image of the drive. Creating a Byte-to-byte Backup in Disk Drill Windows users can recover up to 500 MB of data at no cost. The program lets you create a disk image of your drive for free, and it also comes with a cutting-edge data recovery algorithm that can recover data from your drive as long as it’s detected by your PC. But, in our tutorial, we decided to use a program that lets you create a disk image as well as recover data – Disk Drill. Usually, you would need two separate programs – one to create a disk image of the drive, and a data recovery program to scan the disk for deleted files. If you already lost some data, you can use data recovery programs to scan the disk for recoverable data. This prevents partial data loss because a failing drive could have trouble copying and moving files. It’s recommended that you create a disk image of the drive, rather than copying the contents of the drive manually to the other drive. But, if you notice any of the aforementioned issues, you must migrate your data to a new drive as soon as possible, if you want to keep your data intact. Reallocated sector count warnings are typically not a cause for immediate concern unless the count goes up substantially and other critical S.M.A.R.T. Therefore, there’s no way to fix reallocated sectors on your drive. Once a sector has been reallocated, the hard drive won’t store any information about the original one. How to Fix the Reallocated Sectors Count Warning If the Raw values for these fields are more than zero, your drive could be on the fast lane to failure. This will help you to create a more comprehensive view of the drive. It’s also a good idea to take a look at the Current Pending Sector Count and Reported Uncorrectable Errors S.M.A.R.T. The thing you need to look for is a consistent increase in the Raw values of the Reallocated Sector Count field, over a short period of time. In some drives, 20 reallocated sectors could signal trouble, whereas some disks get by just fine with a reallocated sector count of over 1000. The number of spare sectors differs across hard disk drives. When it comes to the Reallocated Sector Count, the exact numbers do not tell the whole story. However, if the value exceeds zero, you need to be cautious and back up all important data. This indicates that 100% of the spare sectors are available for use, and you have nothing to worry about. Lastly, take a look at the Raw values section.Regardless, it is the minimum acceptable value, i.e., the Current and Worst values should be more than the Threshold value. The Reallocated Sector Count Threshold value will typically be 10 or 36. The Reallocated Sector Count’s Current and Worst values should ideally be 100, 200, or 253, depending on the drive’s manufacturer.monitoring tool and look for the “Reallocated Sector Count” value. Open Crystaldiskinfo or any other S.M.A.R.T.Here’s how to properly read the Reallocated Sector Count field and the associated values: There is a dedicated field called, you guessed it, “Reallocated Sector Count,” that lets you know the number of reallocated sectors on your disk. To see the Reallocated Sector Count for your HDD, you need to install S.M.A.R.T. values mean and indicate, in the section below. ![]() We’ll take a detailed look at what the relevant S.M.A.R.T. (Self-Monitoring, Analysis, and Reporting Technology) report of your drive. You can use these tools to view the S.M.A.R.T. To see the reallocated sector count for your hard drive, you’ll need to use tools like Crystaldiskinfo, or the Disk Utility in UNIX-based OSes. Heavy usage of the drive for extended periods.Ī rapid rise in the Reallocated Sector Count often indicates a failing drive that should be replaced as soon as possible.Physical damage and mechanical issues on the drive.While reallocated sectors are part of the normal wear and tear of a hard disk drive, these factors can cause an unusual increase in their number: Additionally, all further operations to the problematic sector are redirected to the corresponding spare sector. To secure your files, the disk moves the data from these sectors to other, error-free sectors in a special reserved area (spare sectors). Inevitably, some sectors of the hard drive become unfit to store data, i.e., the disk is unable to read, write, or verify the data in the sector. Sectors are the smallest physical storage areas on your disk – usually 512 Bytes in size.
