Cannot Wipe Disk in PBS

Question

I am trying to add an external disk drive to my PBS instance. Everytime when I go to wipe the drive in the GUI I get:

command "wipefs" "--all" "/dev/sdb" failed - status code: 1 - wipefs: error: /dev/sdb: probing initialization failed: No such file or directory

I have tried wipefs

Via CLI I tried:

root@proxmox-backup-server:~# wipefs --all /dev/sdb

wipefs: error: /dev/sdb: probing initialization failed: No such file or directory

and dd

root@proxmox-backup-server:~# dd if=/dev/zero of=/dev/sdb

dd: writing to '/dev/sdb': No space left on device

977+0 records in

976+0 records out

499712 bytes (500 kB, 488 KiB) copied, 0.000980372 s, 510 MB/s

lsblk gives

root@proxmox-backup-server:~# lsblk

NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINTS

sda 8:0 0 476.9G 0 disk

├─sda1 8:1 0 1007K 0 part

├─sda2 8:2 0 1G 0 part

└─sda3 8:3 0 475.9G 0 part

sdb 8:16 0 10.9T 0 disk

I have tried different hard drives and the result is the same.

Any help would be appreciated. Thanks
