  • You've unintentionally deleted the hard drive from the computer using an improper method, causing multiple problems with the file structure, including errors associated with inaccessible file record segments.
  • Corrupted or invalid partition tables can render file record segments inaccessible or unreadable;
  • Sudden and abrupt power surges and outages can corrupt the data stored on internal and external hard disks, causing numerous problems, including file record segment errors.

  • What are file record segments?
    File Record Segment or FRS stands for a Windows file system that stores essential system data about files on internal/external drives, HDDs, SSDs, etc. The FRS file system keeps a record of information such as file type, name, physical address on the drive, date, and more.
    NTFS file systems use file tables, such as Fat Allocation Table (FAT) and Master File Table (MFT), to store these hard drive data records on your Windows computer. Without FRS, your PC cannot access a file you wish to open and view.
  • How big is a file record segment?
    The file record segment is one kilobyte (1,024 bytes) in size.
  • What does it mean when a file is described as "unreadable"?
    It means that your PC can't recognize the file in question due to file system corruption, damaged MFT, or physical damage to the hard drive.
  • What is an orphan file record segment?
    An orphan file record segment is the leftover file that remains on your PC after uninstalling or deleting a program. Though harmless to your computer, these files can easily amass and occupy disk space.
  • Which is better: CHKDSK R or F?
    The chkdsk /f command will check the target drive for logical disk errors, however, it can't scan the drive for bad sectors. The chkdsk /r command, on the other hand, does the same thing as the F command, but can also scan the target location for bad sectors and restore the recoverable files, in case they are still readable.
    So, CHKDSK R is the same as CHKDSK F, only a better and more encompassing command that can identify logical disk errors, find bad sectors, and try file recovery on readable data.
