The type of the file system is EXFAT.
The new file system is FAT32.

Format cannot run because the volume is in use by another
process. Format may run if this volume is dismounted first.
ALL OPENED HANDLES TO THIS VOLUME WOULD THEN BE INVALID.
Would you like to force a dismount on this volume? (Y/N) y
Cannot lock the drive. The volume is still in use.
Format failed.
hmmmm Try removing the drive, rebooting, reinsert the drive. close anything that it opens automatically like an Explorer window, retry the format command.
If that doesn’t work try rebooting to Safe Mode and trying the format command.
In Disk Management what does the drive look like? Does it show it as a single partition?
There is a diskpart option that we could try if these don’t work.
