How to Fix It
1
Check drive health immediately: Download CrystalDiskInfo and check SMART status. Any 'Caution' or 'Bad' rating means the drive needs replacement.
2
Run chkdsk to repair file system errors: Open Command Prompt as Administrator, run: chkdsk C: /f /r — this scans for and attempts to recover bad sectors.
3
Check Event Viewer > Windows Logs > System for disk errors (source: disk, Ntfs, storahci). Repeated errors indicate hardware failure.
4
If using a desktop PC, open the case and check all SATA data and power connections. Reseat cables or try a different SATA port.
5
For NVMe SSDs, ensure the drive firmware is up to date by checking the manufacturer's support website.
6
If the drive is showing bad sectors or SMART warnings, back up all data immediately and plan to replace the drive.
7
Test with a different drive: If possible, install Windows on a different drive or boot from a USB to verify the issue is drive-related and not motherboard-related.
