Summary: Why file record segment becomes unreadable? What are the possible causes behind this issue and how you can resolve it? In this post you will know everything about file segment unreadable issue and solution for this issue.
Before we proceed to fix the File Record Segment is Unreadable issue, let’s understand File Record Segment quickly.
Every file system stores information about the files on a storage drive, which is called File Record Segment (FRS). NTFS stores these records (usually 1KB size) in Master File Table (MFT) and FAT file systems (FAT16/32 & exFAT) store it in File Allocation Table (FAT).
The file record comprises the file name, date, size, type, and physical address of the file on the storage drive. When the OS needs to access a file, it first scans the file system table for the file record, reads the physical address of the file, and then reaches actual location on the drive to read the data.
Bad sectors cause ‘File Record Segments is Unreadable’ error which appears when CHKDSK scan is executed. Windows may also automatically execute CHKDSK scan during the system startup if it finds or detects any inconsistency or disk error.
A bad sector is a cluster of storage blocks on the drive that gets defected and do not respond to any read/write operation. Therefore, when a sector or block where a file record is saved goes bad, the file record segment becomes unreadable. This can happen with both internal and external hard drives including SSDs.
The error is an indicator of a failing drive and poses a significant threat to the data stored on the drive. When Windows can’t find or read the file record in the file system table, you can’t access the data. Unfortunately, these bad sectors can’t be repaired.
Also, when several file record segments become unreadable due to bad sectors, a hard drive may get corrupt and turn RAW or unrecognized by Windows.
There is no way to fix File Record Segment is Unreadable error, as bad sectors can’t be repaired. However, you may try CHKDSK scan and attempt to retrieve information from bad sectors. But this can have adverse effects with the potential of causing data corruption.
The only safe way to get back the inaccessible and lost data due to File Record Segment is Unreadable issue is by using a Windows data recovery software. Following are the steps to get back the data from a disk showing File Record is Unreadable message.
[Caution]: It is strongly recommended to take backup of accessible data before proceeding with further steps.
You can also click on a file to see its preview before saving.
Connect the drive to a different Windows system and access the data. Run CHKDSK scan to see if ‘File Record Segment is Unreadable’ error still exists.
However, if another PC isn’t available or the drive is internal, follow the steps below to create a Live LiveCD and check if your drive is recognizable and data is retrievable.
For this solution, a USB thumb drive of size 8GB or more is required. Once you have the thumb drive, follow the steps, and try recovering the files by using Ubuntu Live CD/USB:
CHKDSK Scan (Optional)
In case hard drive is still not recognized, try running CHKDSK scan by following these steps:
If the same error appears again, use the recommended data recovery method to get back data without damaging it any further. Then format the drive and use a SMART disk analysis tool to check if the drive is failing or it is still usable.
Always keep a backup of the critical files and folders. You can use cloud storage or local external drive for the backup. It will help avoid unforeseen situations such as unreadable file segment record that cause data loss.
Also, defragment your internal and external hard drives once in a while. Alternatively, you may also run CHKDSK scan to keep the drive in good shape. And if the file record segment is unreadable error message appears, use a data recovery software such as the Stellar Data Recovery- Standard to get back your critical data.
