If you're also plagued by this error, worry not. For this tricky issue, the/tool offers three straightforward solutions to help you fix it with ease. Let's delve into the error and explore practical remedies to get things back on track.

Fix: Unable to read file record segment

When dealing with complex errors like "File record segment not readable," it's crucial to explore effective solutions. In this guide, we will walk you through a practical approach to tackle this problem.

Method 1: Clone the Damaged Drive

With the challenge of a damaged hard drive and the risk that file segments may be unreadable, the threat of data loss looms large. Any action taken on the affected drive can exacerbate the situation, leading to more severe damage.

To mitigate this risk, it is advisable to use a reliable disk-management tool that treats the cloning of data off the damaged drive as a first priority. Cloning creates a replica, ensuring that the original data remains intact and minimizing the prospect of further loss.

In this scenario, the Partition Master Professional tool becomes a valuable ally. This software offers a user-friendly interface and powerful disk cloning capabilities, designed to streamline the cloning process and make it accessible to users with limited technical knowledge.

Step 1: Select the source disk.

    Click "Clone" on the left menu. Choose "Clone System Disk" or "Clone Data Disk", then click "Next". Select the source disk, then click "Next".

Step 2: Select the target disk.

    Select the HDD/SSD you want as the target disk and click “Next” to continue. Read the warning message and confirm by clicking the “Yes” button.

Step 3: Review the disk layout and edit the size of the target disk partitions, if necessary.

When warned that all data on the target disk will be erased, click Continue (back up any important data on the target drive first).

Here you can choose to “Automatically adjust the disk size,” “Clone to the same size as the source disk,” or “Edit disk layout.” (Choose the last option if you want to allocate more space for the C drive.)

Click “Start” to begin cloning the hard drive.

Method 2: Run the CHKDSK Command Prompt

CHKDSK, short for Check Disk, is an inbuilt Windows utility that scans and fixes disk errors. To resolve the issue of unreadable file record segments, it's recommended to run the chkdsk /f /r /x command. Follow the steps below to solve the problem and restore your drive's functionality.

Step 1: Right-click the Start button, select “Command Prompt,” and run it as administrator.

Step 2: Type the drive letter, and press Enter.

Step 3: Type the command chkdsk /f /r /x and press "Enter."

chkdsk f r x

  • /f Fixes errors found.
  • /r Locates bad sectors and recovers readable information.
  • /x Forces the volume to dismount first if necessary.

Step 4: Press “Y” to confirm that you want to run CHKDSK the next time you restart your system.

5. Close all programs and restart your computer to begin the CHKDSK process.

Method 3: Connect the damaged drive to another computer

When troubleshooting the “File record segment cannot be read” error, you can opt for an alternative method that involves connecting the damaged drive to another computer. If you have access to a second PC, you can attempt potential recovery using the following steps.

Step 1: Make sure the second computer is powered off before you connect the failed hard drive to it.

Step 2. Connect the damaged drive to a second computer using an external enclosure, a USB-to-SATA/IDE adapter, or a compatible dock.

Step 3: On the second computer, wait for the system to detect the newly connected drive.

Step 4. Open File Explorer and see if the damaged drive is accessible on the second computer.

Step 5 If you have access, copy important data from the damaged disk to the second computer.

Step 6. On the second computer, open a Command Prompt as an administrator, and run CHKDSK with the /f switch on the damaged drive.

Step 7: Safely remove the damaged hard drive from the second computer.

Possible reasons why a file segment may fail to read

Understanding the possible causes of the "File Record Segment Cannot Be Read" error is crucial to prevent it from happening again in the future. Let's delve into some potential reasons behind this perplexing issue.

  • Power outage or surge: Sudden power loss or a power surge can negatively affect the data on your hard drive, potentially causing file record segment corruption.
  • Bad sectors on the hard drive: The presence of bad sectors on the drive can interfere with the normal functioning of file record segments, leading to read errors.
  • MFT (Master File Table) or FAT (File Allocation Table) corruption: Logical or physical damage to the Master File Table (MFT) or File Allocation Table (FAT) may render file record segments unreadable.
  • Improper hard drive deletion: If a hard drive is improperly deleted, it can result in inconsistent file structures, leading to errors associated with unreadable file record segments.
  • Virus or malware attack: Viruses or malware can target the integrity of file structures, including file record segments, making them inaccessible.
  • Corrupted partition table: A corrupted partition table can lead to unreadable file record segments. You need to repair an invalid partition table to prevent loss of accessibility to the entire drive.
