GParted 搞砸了我的分區

執行testdisk我實際上可以看到我的所有文件/dev/sda1！

我想在安裝 Debian 的同時安裝 Windows 以玩一些遊戲。為此，我必須啟動 Ubuntu Live 12.1 DVD 並使用 GParted（我正在調整包含所有內容的主分區的大小）。

調整大小成功完成。然後我嘗試重新啟動到我的 Debian 以備份我的數據，不幸的是，我之前忘記了這樣做。

GRUB 載入良好，但係統無法正常啟動！它會嘗試配置“ramdisk”或類似的東西；那麼這只是一個提示，僅此而已。

現在我再次啟動到 Ubuntu，檢查我的縮小分區。本質上，它已損壞，但我無法真正理解錯誤消息。

這是 GParted 報導的：

GParted 0.12.1 --enable-libparted-dmraid

========================================

這是的輸出dmesg | tail：

如何修復我的分區？我能恢復我的數據嗎？

以下是我執行的一些附加命令：

須藤 fsck.ext3 -cf /dev/sda1

分區表條目狀態為“msdos” - 這應該是這樣嗎？

嘗試重新啟動到實時環境，並且沒有任何系統分區fsck.ext3 -pcf在相關驅動器上執行。如果fsck.ext3不可用，則e2fsck -pcf可以正常工作。

使用的標誌將告訴fsck.ext3行為如下：

-p, Automatic repair (no questions)
-c, Check for bad blocks and add them to the badblock list
-f  Force checking even if filesystem is marked clean

如果這不起作用，請執行並使用該fdisk /dev/sda選項來驗證partition table. 我相信這個選項是v
