How to Check Your Drive's Health

  1. Download and install CrystalDiskInfo from the official download page.
  2. Launch the application. It will automatically scan and list all connected drives.
  3. Check the "Health Status" column. A "Good" status means your drive is healthy. "Caution" or "Bad" requires immediate attention.
  4. Click on a drive to see detailed S.M.A.R.T. attributes like temperature, power-on hours, and read error rate.
  5. Enable the Resident function to monitor your drives continuously from the system tray.

Understanding S.M.A.R.T. Attributes

S.M.A.R.T. (Self-Monitoring, Analysis, and Reporting Technology) is a monitoring system included in hard drives and SSDs. Here are the key attributes to watch:

  • 05 Reallocated Sectors Count: A high value indicates bad sectors that have been remapped. A rising count is a sign of imminent failure.
  • C4 Reallocation Event Count: The total number of remap operations. A high number is concerning.
  • C5 Current Pending Sector Count: The number of unstable sectors waiting to be remapped. If this is non-zero, back up your data.
  • C6 Uncorrectable Sector Count: The number of uncorrectable errors. Any value here is critical.
  • C7 Interface CRC Error Count: Usually indicates a bad cable. Try replacing your SATA cable.
  • Power On Hours: The total time the drive has been powered on. Useful for estimating remaining lifespan.

How to Use AAM/APM Controls

AAM (Automatic Acoustic Management) and APM (Advanced Power Management) allow you to control the noise and power consumption of your hard drives.

  1. Select a drive in the main CrystalDiskInfo window.
  2. Go to Function > Advanced Feature > AAM/APM Control.
  3. For AAM: Set the acoustic level. "Quiet" minimizes noise but may reduce performance. "Performance" maximizes speed.
  4. For APM: Set the power level. Lower values save power but may slow down the drive's response time.
  5. Click "Set" to apply the changes. These settings are not permanent and may reset after a reboot on some drives.

Setting Up Temperature Alerts

  1. Go to Function > Alert Settings.
  2. Check "Temperature Alert" and set your desired threshold (e.g., 50°C for HDDs, 70°C for SSDs).
  3. Choose your alert method: Sound, Mail, or Tray balloon notification.
  4. For email alerts, enter your SMTP server, port, username, password, sender, and recipient email addresses.
  5. Click "Apply" to save your settings. CrystalDiskInfo will now monitor temperatures in the background and alert you if they exceed the threshold.

Troubleshooting: "No Disk Found"

If CrystalDiskInfo reports "No Disk Found," here are the steps to diagnose the issue:

  1. Check CrystalDiskInfo version: Ensure you have the latest version installed.
  2. Run as Administrator: Some controllers require administrative privileges to access S.M.A.R.T. data.
  3. Check USB bridges: Ensure your USB enclosure supports S.M.A.R.T. passthrough. Some cheap enclosures block this data.
  4. RAID configurations: CrystalDiskInfo does not support all RAID controllers. Try switching to AHCI mode in your BIOS if possible.
  5. Intel RST/VMD: If using Intel RST or VMD, CrystalDiskInfo may require specific drivers to detect the drives.
  6. Reinstall CrystalDiskInfo: A corrupted installation can sometimes cause detection issues.
