Every hard drive fails eventually. The difference between losing your data and not losing it comes down entirely to whether you had warning and acted on it. Most failing drives give significant warning before complete failure.
READ YOUR SMART DATA
Hard drives continuously monitor their own health via SMART (Self-Monitoring, Analysis and Reporting Technology). Free tool CrystalDiskInfo reads this data in plain language. Install it and check your drives now.
SMART attributes that matter most:
- Reallocated Sectors Count — Any value above zero is a warning. Rising value means back up immediately.
- Pending Sector Count — Sectors suspected bad but not confirmed. Rising count means imminent problems.
- Uncorrectable Sector Count — Permanently failed sectors. Non-zero means the drive has unrecoverable bad spots.
⚠️ CrystalDiskInfo showing "Caution" or "Bad" means back up everything today before doing anything else. Do not wait.
BEHAVIORAL SIGNS
- Specific files that regularly fail to open
- Windows taking much longer than usual to boot
- Programs that worked fine now refusing to launch
- The clicking sound described in our noise post
