What to do when you receive the error message “file record segment is unreadable”. What causes this problem? In Partition Magic, you will learn about the causes of file record segment unreadable and its solutions.
Have you ever encountered the error “file record segment is unreadable” when you check SSD, Western Digital or other disks using the CHKDSK command line? If so, don’t worry. The following content will show you several ways to solve it.
Before trying the following methods, let’s understand what a file record segment is. Each file on an NTFS volume is represented by a record in the Master File Table (MFT). The total number of File Record Segments (FRS) depends on the number of files stored on the NTFS partition, which in turn determines how many File Record Segments there are in the MFT.
Reason Why the File Record Segment Is Unreadable
The following are some possible reasons why a file record segment is unreadable:
- Bad sectors on the hard drive: Bad sectors can cause CHKDSK segment unreadable error when performing a CHKDSK scan.
- Damaged FAT (File Allocation Table) or MFT: Physical or logical damage to both will cause Windows to be unable to read the file record segments.
- Power outage on the computer: Sudden power outages can adversely affect the data stored on the hard drive and can cause the corrupt file record segment error.
- Attacked by viruses or malware: Viruses or malware can affect the integrity of the file structure, including the file record segments.
- Improper deletion of the hard drive: If the hard drive is improperly deleted, it can cause inconsistencies in the file structure, leading to related errors such as unreadable file record segments.
- Damaged partition table: Damaged partition table can cause unreadable file record segments.
How to Fix File Record Segment Is Unreadable
It is annoying when you encounter the problem of corrupt file record segment. And it is crucial to explore effective solutions. Below it will tell you four practical ways to fix this problem. You can try them one by one until the error gets solved.
Way 1: Run the CHKDSK
CHKDSK is a Windows built-in utility that scans and repairs errors on your disk. When your disk has CHKDSK segment unreadable problem, you can run chkdsk /f /r /x command to fix this problem. Follow the steps below step by step.
Step 1: Type Command Prompt in the Search box, and right-click it to choose Run as administrator to open.
Step 2: Type chkdsk e: /f/r/x (e is the drive letter of the partition having the unreadable file record segment issue) in the CMD interface and hit the Enter key.
The different parameters have different meanings:
- chkdsk /f – Find any drive errors and try to fix them.
- chkdsk /r – Locate bad sectors on the drive and try to recover any and all readable information from them.
- chkdsk /x – Force the volume you’re about to check to be dismounted.
Step 3: After completing the scan and repair, the bad sectors have been masked. Close all applications and restart your computer to initiate CHKDSK.
Alternatively, you can also try to use the Surface Test and Check File System feature of MiniTool Partition Wizard to check if the hard disk has errors and repair it. You can refer to the short steps below.
