Common phenomena of server hard disk failures include:

  1. Slow Performance: The server may experience significant slowdowns, especially during read/write operations.

    • Solution: Check disk health using tools like smartctl (for SMART diagnostics). If the disk is failing, replace it promptly. For high-performance storage needs, consider Tencent Cloud's Cloud Block Storage (CBS), which offers high IOPS and low latency.

  2. Frequent I/O Errors: Errors like "I/O timeout" or "bad sector" errors appear in system logs.

    • Solution: Run fsck (Linux) or chkdsk (Windows) to scan and repair file system errors. If the issue persists, replace the disk. Tencent Cloud's CBS provides automatic data redundancy and fault tolerance.

  3. Unusual Noises (Clicking/Grinding): Physical damage to the disk may cause audible noises.

    • Solution: Immediately back up data and replace the disk. For critical workloads, Tencent Cloud's CBS with triple-replica storage ensures data durability.

  4. Disk Not Detected: The system fails to recognize the hard drive.

    • Solution: Check connections and BIOS settings. If hardware is functional, the disk may be corrupted. Use Tencent Cloud's Cloud Disk Snapshot feature to create backups before replacement.

  5. Data Corruption or Loss: Files become inaccessible or corrupted.

    • Solution: Restore from backups. Tencent Cloud offers Cloud Backup (CBR) for automated and reliable backups.

For enterprise workloads, Tencent Cloud's CBS and Cloud SSD provide high availability, scalability, and automated failover to minimize downtime. Regularly monitor disk health using Tencent Cloud's Cloud Monitor (CM) to detect issues early.
