BSOD with NTFS_FILE_SYSTEM during heavy disk write operations on an aging hard drive

The problem: System crashes with NTFS_FILE_SYSTEM error specifically during large file copy or write operations, correlating with an older hard drive.

Symptoms: BSOD occurs during large file transfers, downloads, or disk-intensive operations; drive shows signs of aging (unusual sounds, slower performance over time); chkdsk may report errors on the affected volume.

Likely cause: Developing bad sectors or mechanical degradation on an aging hard drive is corrupting file system metadata during write operations, which NTFS detects as a fatal inconsistency triggering the crash as a protective measure.
