External USB Harddrive not recognized

I got an external HardDrive that I want to перекаверверсия. I don't know what the previous user did, but it was definitely в программное обеспечение change.

lsusb recognizes в harddrive with the following output:

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

it also appears to under ’/dev /' эксперт '/sdb'

sda
sda1
sda2
sda5
sdb

however ’lsblk’, ’fdisk’, ’gparted’ and ’testdisk’ don't recognize it.

mounting doesn't work either

the output of the 'dmesg' is:
