外部硬盘在 usb 2.0 下可以工作，但在 usb 3.0 下会安装几秒钟然后卸载。我不认为这是硬盘的问题，因为它在 usb 2.0 下工作正常。

Ubuntu 偶尔会弹出错误信息：
Error mounting /dev/sdb1 at /media/colin/7607B44F50711B5C: Command-line `mount -t "ntfs" -o "uhelper=udisks2,nodev,nosuid,uid=1000,gid=1000,dmask=0077,fmask=0177" "/dev/sdb1" "/media/colin/7607B44F50711B5C"' exited with non-zero exit status 13: ntfs_attr_pread_i: ntfs_pread failed: Input/output error
Failed to read NTFS $Bitmap: Input/output error
NTFS is either inconsistent, or there is a hardware fault, or it's a
SoftRAID/FakeRAID hardware. In the first case run chkdsk /f on Windows
then reboot into Windows twice. The usage of the /f parameter is very
important! If the device is a SoftRAID/FakeRAID then first activate
it and mount a different device under the /dev/mapper/ directory, (e.g.
/dev/mapper/nvidia_eahaabcc1). Please see the 'dmraid' documentation
for more details.
