Windows was unable to complete the format​? Help!

Hey guys. I’m trying to reformat my USB drive to make it a bootable disk, but I keep getting errors. (SanDisk Ultra Dual Drive Go USB) In File Explorer, it shows “Windows was unable to complete the format”.

I tried diskpart with clean, create partition primary, and format, but it just says “Format failed”. Does anyone have suggestions on what might be wrong or how I can forcefully reformat it? TYSM!

    Sometimes, hardware issues mean the drive is failing and can’t be properly formatted. If this is the case, the drive might need replacing.
