Case: I got "file record segment is unreadable" when using chkdsk

Hi, I've been having boot problems with Windows 10 on my Asus laptop for a few days. The system crashed after opening a word doc and now won’t reboot. Tried chkdsk command line 3 times, but I got “file record segment is unreadable” each time. Does this mean my hard drive is no longer usable? Is there any way to save it? Or is it hopeless? Thanks

What is file record segment?

File Record Segment (short for FRS) refers to file system that store information (eg: file name, date, type, and physical address) about files on internal and external hard drive, SSDs, laptop, Western Digital, etc.

NTFS stores these records in Master File Table (MFT) while other file systems (eg: FAT, FAT16, FAT32, exFAT) store record in File Allocation Table (FAT). That is to say, the total number of file record segments depends on the number of files saved on the partition with a specific file system, which in turn determines how many file record segments are in the MFT or FAT.
