Are hard disk's bad sectors filesystem dependent?

I was wondering where defective sectors are stored on the hard disk:
- in a filesystem independent area, so that if the hard disk is formatted again with same/different filesystem they will show as bad?



I ask this because my digital sat PVR's hard disk was showing a buggy behavior, so I have attached the HD to my PC, however as it uses a proprietary filesystem (XTV), I have formatted it with NTFS and issued CHKDSK /F /R to verify sectors: as a result 24 sectors were marked as bad.



Unmounted the disk and plugged into the PVR, the disk was re-initialized with XTV filesystem.




At this point I wonder if the sectors marked as bad are still flagged or not
