我有一个外部硬盘，想恢复。我不知道之前的用户做了什么，但肯定是软件更改了。
lsusb 通过以下输出识别硬盘：
Bus 002 Device 006: ID 174c:55aa ASMedia Technology Inc. ASM1051E SATA 6Gb/s bridge, ASM1053E SATA 6Gb/s bridge, ASM1153 SATA 3Gb/s bridge
它也出现在“/dev/”下作为“/sdb”
sda
sda1
sda2
sda5
sdb
但是“lsblk”、“fdisk”、“gparted”和“testdisk”无法识别它。
安装也不起作用
‘dmesg’的输出是：
