Hi robin schore, I completely understand how frustrating this must feel you’ve already tried different ports formats and even bought a brand-new flash drive yet the recovery tool still refuses to recognize it.
To fix this check in Disk Management if your USB shows as removable because the Recovery tool won’t work with fixed disks. If it’s fine erase all partitions create one primary partition and format it as FAT32 or NTFS. Plug it into a rear USB port and run reagentc /info and reagentc /enable in Command Prompt to make sure the recovery environment is active. If it still doesn’t work use Microsoft Media Creation Tool to make a bootable USB or try thirdparty tools like Macrium Reflect or AOMEI Backupper for a full rescue drive.
When you open Disk Management does your USB show as Removable or Fixed?
Best regards
