你的電腦變慢、頻繁卡頓，可能是硬盤出現壞道，應立即運行chkdsk /f /r（Windows）或磁盤工具急救（Mac）並備份數據；2. 聽到異響如咔噠聲或摩擦聲，說明機械部件可能損壞，需立刻停用硬盤並尋求專業(yè)恢復服務；3. 文件丟失或無法打開，表明文件系統(tǒng)或物理損壞，應停止寫入新文件並使用Recuva等工具嘗試恢復；4. 頻繁崩潰或提示“無啟動設備”，需通過U盤啟動判斷是否為硬盤問題，並儘快更換硬盤——關鍵在於及時備份，否則數據風險極高。

If your computer is acting up—slow performance, strange noises, or files vanishing—it might not be a software glitch. It could be your hard drive quietly failing. Hard drives don't usually die suddenly; they often give warning signs first. Catching these early can save your data and prevent a full-blown disaster.

Here are the most common signs your hard drive is failing—and what to do about it:

1. Slow Performance and Frequent Freezing

If your system takes forever to open files, apps freeze randomly, or the spinning wheel (or “beach ball”) shows up constantly, your drive might be struggling to read data. This often happens when the drive has bad sectors—areas that can't reliably store data anymore.

What to do:

• Run a disk check tool:
  • On Windows: Open Command Prompt as admin and type chkdsk /f /r
  • On Mac: Use Disk Utility > First Aid
• Back up your data immediately—even if the drive still works.

2. Unusual Noises (Clicking, Grinding, Beeping)

Mechanical hard drives (HDDs) make some noise, but loud clicking, grinding, or repetitive beeping is a red flag. These sounds often mean the read/write head is misaligned or the motor is failing.

What to do:

• Stop using the drive right away—continued use can cause permanent damage.
• Don't try DIY fixes like freezing the drive (yes, people still try this—it rarely works and often makes things worse).
• Consult a professional data recovery service if the data is critical.

3. Files Are Missing, Corrupted, or Can't Be Opened

If documents, photos, or programs suddenly won't open—or disappear entirely—it's a strong sign of file system corruption or physical drive failure.

What to do:

• Immediately stop saving new files to the drive—it could overwrite recoverable data.
• Try data recovery software like Recuva (Windows) or Disk Drill (Mac/Windows) before the drive dies completely.
• If recovery tools fail, again: professional help may be your only option.

4. Frequent Crashes or Boot Errors

If your computer won't boot or gives errors like “No bootable device” or “Operating System not found,” the drive may be failing to read critical system files.

What to do:

• Try booting from a USB drive or external OS to see if the problem is the drive or something else.
• If the drive is the issue, replace it ASAP—but only after backing up what you can.

Bottom Line

Hard drive failure isn't always preventable, but catching it early gives you a fighting chance. The single most important thing? Back up your data regularly. Whether it's cloud storage, an external drive, or both—don't wait until it's too late.

If you're seeing any of these signs, act fast. A failing drive won't get better on its own—it'll only get worse.
