Ubuntu找不到额外的（扩展）硬盘

悬崖勒马2011 · #1

我在我的电脑上安装了一个新硬盘（〜4TB），除了以前已有的硬盘（〜200G）之外，我找不到这个新的。系统是ubuntu-14.04（64位）.

当我输入“sudo lsblk”时，显示：

我只想使用这个新磁盘来扩大我的存储空间。感谢您的帮助！

新硬盘（〜4TB）

1. 使用同一版本 Ubuntu Live CD/DVD/USB 開機
登入試用桌面把下面指令複製貼進終端機執行
1-0. sudo efibootmgr -v
1-1. sudo parted -l print
1-2. sudo ls -al /dev/disk/by-uuid/*
1-3. sudo ls -al /dev/disk/by-partuuid/*
1-4. sudo apt-get install fsarchiver
1-5. sudo fsarchiver probe detailed
把結果全部直接選取/複製/貼上來
不要摘錄以免遺漏重要訊息
不要擷圖方便回文直接引用你貼上來的資料方便你閱讀

我暂时找不到相应的CD 和USB，就直接在系统输入了以下命令，不知可否有用？

新硬盘（〜4TB）

我暂时找不到相应的CD 和USB，就直接在系统输入了以下命令，不知可否有用？

sudo efibootmgr -v
sudo: efibootmgr: command not found

sudo parted -l print
Model: ATA Crucial_CT256MX1 (scsi)
Disk /dev/sda: 256GB
Sector size (logical/physical): 512B/4096B
Partition Table: msdos

1. 表示你這次開機是在 Legacy Bios 開機模式 (非 UEFI 開機模式)
1-1. 通常 Legacy Bios 開機開機硬盤使用 msdos 分割模式（或稱 mbr 模式）
最高只能存取到 2TB 超過 2TB 的容量無法存取但是硬盤應該可以使用
1-2. 如果你的電腦支援 UEFI 開機模式開機硬盤需要 gpt 分割模式可以存取 4TB 硬盤的內容

使用同一版本 Ubuntu Live CD/DVD/USB 開機
登入試用桌面把下面指令複製貼進終端機執行

1-3. 這是在支援 UEFI 開機模式下不須重新安裝 Ubuntu 就能夠存取 4TB 硬盤的內容的簡易方法

sudo fsarchiver probe detailed
... 略

2. 猜測
你的硬盤只有兩個分割區 /dev/sdsa1 /dev/sda2
然後在 /dev/sda2 上設定 LVM 再分割成 dm-0 ( 掛載 / ) 及 dm-1 (swap)
其它硬盤空間未分配或未能存取

3. 查一下你的電腦是否支援 UEFI 開機模式
