On modern drives, running a "Low Level Format" does not alter the physical sector geometry. The drive firmware handles this internally. Users attempting to change the sector size (e.g., 512e to 4Kn) via this tool will likely fail, as this requires manufacturer-specific proprietary tools.
Solution: After LLF, the drive has no partition table. Go to Disk Management > Rescan Disks > Initialize Disk. hdd llf low level format tool full updated
