我挖出了一个旧硬盘，想看看里面有什么。我不记得它是否曾经分区过，是否运行 Windows，或者它是否只是一个备份磁盘。
这是我所做的：
插入磁盘，Ubuntu才不是识别磁盘并且不会自动挂载。
打开分区. 看到这个错误：
Invalid argument during seek for read on /dev/sdd然后在 /dev/sdd 上显示未分配的 2.73 TB

这是 Seagate 3TB 的劣质硬盘之一，故障率很高（并且会引发集体诉讼）。这个硬盘只是一块未分区的空硬盘吗？它还能正常工作吗？
我即将重新格式化此磁盘，但我想确保不会覆盖任何内容。这样安全吗？
答案1
看起来您可能正在使用 USB 外壳。
你怎么知道的？SMART 报告磁盘高级格式（4096 字节物理扇区），但fdisk看到的是 512 字节物理扇区。USB 外壳显示 512 字节物理扇区，尽管这并不正确。 更多详情请点击这里。
我看到fdisk只能看到4294967295 blocks或。 USB 外壳可能根本2TiB无法使用超过的高级格式磁盘。 我建议：2TiB
- 获取支持高级格式化的新外壳或
- 通过 SATA 电缆将磁盘直接插入计算机。
某些 USB 外壳可以处理高级格式化，但仍会报告 512 字节物理扇区。如果您有这样的外壳，为了安装此磁盘，您应该让 Linux 忽略错误的扇区大小。以下是使用回送设备：
LODEVICE="$(losetup -f)"
sudo losetup "$LODEVICE" /dev/sdd
sudo partprobe "$LODEVICE"
运行后losetup，您应该有一个名为的设备/dev/loop#，其中/dev/loop#存储在的字符串$LODEVICE。
运行后partprobe，您应该有一个名为 的设备/dev/loop#p1。
可能还有其他分区，您可以使用该lsblk命令找到它们。输出应该类似于以下内容：
NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
⋮
loop# 7:0 0 22.4G 0 loop
├─loop#p1 259:0 0 512M 0 loop
├─loop#p2 259:1 0 244M 0 loop
└─loop#p3 259:2 0 21.6G 0 loop
如果您想要挂载第一个分区/mnt，您可以这样做：
sudo mount "${LODEVICE}p1" /mnt
然后您可以跑去ls /mnt看看里面有什么。
卸载完成后，您可以像这样断开环回设备：
sudo losetup -d "$LODEVICE"
