原因五：文件系统损坏

       Corrupted file systems, such as NTFS or FAT32, can make硬盘 unreadable. According to Western Digital, this often occurs due to improper ejection or power outages. A user reported that their硬盘 became RAW format after a sudden shutdown, and another案例 saw a macOS user unable to access an exFAT-formatted drive due to corruption from cross-platform use.

解决方法五：修复文件系统使用工具

       Run built-in tools like CHKDSK in Windows or Disk Utility in macOS to scan and repair errors. For severe cases, data recovery software might be necessary. In the RAW format案例, the user used CHKDSK /f command, which recovered the drive based on Microsoft's guidance, though some data was lost due to the extent of damage.

原因六：分区表错误

       Damaged partition tables, often caused by virus attacks or software conflicts, can prevent硬盘 recognition. Seagate's technical notes indicate that this is a common issue after malware infections. A案例 involved a user whose硬盘 showed no partitions after a virus scan deleted critical table entries; another was a dual-boot system where partition overlapping occurred during installation.

解决方法六：重建分区表

       Use tools like TestDisk or Windows Disk Management to recreate the partition table. Always back up data first if possible. In the virus案例, the user ran TestDisk following official tutorials and successfully restored the partitions without data loss.

原因七：物理损坏或坏道

       Physical damage, such as head crashes or bad sectors, can render硬盘 unrecognizable. Toshiba's support documents warn that drops or overheating are primary causes. A案例 featured a laptop硬盘 that stopped working after a fall, with clicking noises indicating mechanical failure; another had gradual bad sector accumulation leading to detection failures over time.

解决方法七：数据恢复或 replacement

       For physical damage, professional data recovery services are recommended. If the硬盘 is under warranty, contact the manufacturer for replacement. In the fall案例, the user sent the drive to a lab like DriveSavers, recovering most data but ultimately replacing the硬盘 as per Seagate's advice.
