旧的外置硬盘已经积尘 8 年了，现在我需要从中得到一些东西。我把它插入我的 ubuntu 18.04 笔记本电脑，但什么也没得到。过去几周我一直在尝试诊断，但什么也没找到。我跳转到了可能有 30 或 40 个不同主题，这些主题有类似或相关的问题，我尝试了其中所有有意义的方法，但我仍然有基本问题。
dmesg：
[ 194.381226] usb 1-5: new full-speed USB device number 12 using xhci_hcd
[ 194.533476] usb 1-5: New USB device found, idVendor=0928, idProduct=ffff
[ 194.533480] usb 1-5: New USB device strings: Mfr=0, Product=0, SerialNumber=0
这是 /dev/ 中的内容
$ ls /dev/ | grep sd
sda
sda1
sda2
sda3
sdb
sdb1
请注意，sda 是主磁盘，sdb 是笔记本电脑上的额外内部磁盘。

我遵循了此帖子评论中的建议：无法安装 Seagate 2T 外置硬盘，lsusb 可以检测到，但 fdisk -l 无法检测到 第二条评论是关于
到 /var/log/syslog 查找 idVendor 和 idProduct：
当然，修改以匹配我的，如下所示：
echo options usb-storage quirks=0928:ffff:u > /etc/modprobe.d/ignore_uas.conf
但还是没有变化。
我发现这些线程通常没有太多动静，但如果有人能帮助我和其他陷入困境的人，我想我会问这个问题。
