Terminal
fsck 有效選項無效
我有一張損壞的 micro SD 卡,我不小心拔出了。我想使用fsck實用程序搜尋並修復任何錯誤。

為什麼
-p
選項在幫助中說它是無效的Automatic repair (no questions)
?那我該如何修復我的 SD 卡呢?
在這兩種情況下查看輸出的第二行。
fsck --help
已使用fsck.ext3
(系統上的預設設置)並顯示了對該工具有效的選項,但fsck -p /dev/mmcblk0
使用exfatfsck
它是因為這適合您的 SD 卡。不幸的是
exfatfsck
無法修復錯誤,它只能報告它們。所以執行fsck /dev/mmcblk0
查看是否有任何錯誤;如果有,您將需要其他一些策略來修復文件系統:
- 使用具有能夠修復文件系統的工具的另一個作業系統(Windows?);
- 或在 Linux 上,將所有文件複製到其他地方並重新格式化卡。
