These tools can:

Warning: Using the wrong tool or firmware can brick the USB drive permanently.

Since you cannot access the hardware directly, you must use specialized software that sends SCSI pass-through commands to the USB controller. HDD Low Level Format Tool (by HDDGURU) is the industry standard for this. usb lowlevel format

The USB low-level format is a powerful, last-resort tool. It is not something you should do before ejecting a drive or to delete a few files. It is the digital equivalent of a factory reset and a firehose cleaning combined.
