我有点迷茫了。我拿到了我值得信赖的旧式 500Gb 外置 USB 驱动器，但它拒绝安装：
我认为我的分区表无效：
sudo fdisk -lu /dev/sdb
Disk /dev/sdb: 500.1 GB, 500107862016 bytes
255 heads, 63 sectors/track, 60801 cylinders, total 976773168 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x4e5041f4
Device Boot Start End Blocks Id System
/dev/sdb1 16065 976768064 488376000 f W95 Ext'd (LBA)
/dev/sdb5 16128 976768064 488375968+ 7 HPFS/NTFS
sudo sfdisk /dev/sdb
Checking that no-one is using this disk right now ...
OK
Disk /dev/sdb: 60801 cylinders, 255 heads, 63 sectors/track
Old situation:
Units = cylinders of 8225280 bytes, blocks of 1024 bytes, counting from 0
Device Boot Start End #cyls #blocks Id System
/dev/sdb1 1 60800 60800 488376000 f W95 Ext'd (LBA)
/dev/sdb2 0 - 0 0 0 Empty
/dev/sdb3 0 - 0 0 0 Empty
/dev/sdb4 0 - 0 0 0 Empty
/dev/sdb5 1+ 60800 60800- 488375968+ 7 HPFS/NTFS
Input in the following format; absent fields get a default value.
<start> <size> <type [E,S,L,X,hex]> <bootable [-,*]> <c,h,s> <c,h,s>
Usually you only need to specify <start> and <size> (and perhaps <type>).
最后 dmesg

答案1
看起来驱动器现在出现了一些错误，DMESG 输出很好地显示了这一点。这些逻辑块看起来位于定义的分区内，但这似乎足以让操作系统不想安装该设备。此时，我会向smartctl -a /dev/sdb它抛出错误，看看它会产生什么结果。这应该会提供驱动器的 SMART 信息，并显示它是否真的出现了坏簇。
