Step 3: Search for lost files in Path section or use Type, Find or Filter option to quickly find needed files. And then, check needed items and save them to a safe location.

After recovering all lost files due to CHKDSK file record segment unreadable on the hard drive, you can choose to reformat your drive.

Just go to Disk Management, right-click on the drive with the issue of file segment is unreadable to choose Format, configure file system, volume label, and allocation unit size.

Way 4: Connect the Hard Drive to a Different PC

In addition to cloning a disk and performing data recovery, there is another way to salvage your files in case of CHKDSK file record segment unreadable.

That is to connect the drive to a different PC by connecting the drive internally or by using a hard drive enclosure. If you are able to access it, copy all your important files as many as possible.


Hard drive failure can be devastating and unreadable sections of data will only get worse, hence, recovering as much data as you can is the best way. And then, we strongly advise that you replace the damaged hard drive with a new one after a backup (especially disk cloning) or data recovery.


Do you use chkdsk /f command line to test your drive but receive “chkdsk is verifying files file record segment is unreadable” error message in Windows 10/8/7/XP? Actually, it is due to bad sectors.

However, you cannot fix physically damaged disk but shield these bad blocks and then back up crucial data with three ways: clone a hard drive, recover data or connect the problematic disk to another PC to copy files. Please choose a suitable one based on the actual situations.

File Record Segment Is Unreadable FAQ

What is a file record segment?
To put it simply, 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 saved on the NTFS partition, which in turn determines how many file record segments are in the MFT.
Which is better chkdsk R or F?
chkdsk /r locates bad sectors and recovers readable information while chkdsk /f checks and fixes disk errors, not bad sectors. These two commands focus on different things, so in our opinion, they are not comparable.
How do I open the file or directory is corrupted and unreadable?
If you receive the error “file or directory is corrupted and unreadable”, you can try fixing it. Just carry out chkdsk to check and repair errors, format the corrupted partition for reuse, etc. For more information, refer to this post – Quickly Fix: The File or Directory Is Corrupted and Unreadable.
What is an orphan file on a computer?
An orphan file is a support file on the hard drive that no longer has a purpose since the parent app that it is related to has been uninstalled or removed. If you make sure the file is not being used by any other program, you can delete it manually.
