Practical workflow — how to diagnose a suspect drive
- Backup important data immediately if accessible.
- Check SMART attributes with a quick tool (CrystalDiskInfo, DriveDx, or smartctl).
- Run a vendor/self-test (short then long) using smartctl, SeaTools, or GSmartControl.
- Perform surface scans (HD Tune, HDDScan, Victoria) to map bad LBAs.
- Attempt non-destructive repair/remap only after backups (Victoria, MHDD).
- If data is critical and drive is failing, consult a professional recovery service.
Tips and cautions
- SSDs behave differently: avoid running unnecessary full-surface write tests on SSDs — prefer SMART/firmware diagnostics and vendor tools.
- Remapping and low-level repairs can hide underlying failures; remapped sectors often mean the drive is degrading.
- Always have a verified backup before attempting write-intensive repairs.
- For servers, use smartd (smartmontools) for continuous monitoring and alerts.
Final thoughts
By 2025, diagnostic needs still depend on the media type (HDD vs SSD), urgency, and whether you need a simple health check or deep recovery tools. For everyday users, start with CrystalDiskInfo/DriveDx and backups. For professionals, smartmontools, Victoria, and specialized recovery suites remain indispensable.
If you want, I can: 1) expand any tool’s section with step-by-step instructions, 2) provide sample smartctl commands for common checks, or 3) create a printable checklist for drive diagnostics. Which would you like?
