64 gb USB now turned into 32 only

I have a 64 USB memory which I confirmed was 64 gb before this happened. I used this stick to create a boot USB, which served its purpose. I wanted to reformat it but it now said only 32 gb.

How do I bring it back to 64gb?

Check disk management to see if there is another partition on the drive. If not, its probably one of those fake drives.

I saw the unallocated partition in disk management but could not expand the partition. Downloaded a free partition program and did the job.

Seem like a problem created by using the 64gb to make a boot device.

Sounds like it was formatted with FAT32, which has a 32GB limit.
I think when you create a boot USB, the program (either MS Windows Installer, or Macrium Reflect), it automatically formats it to FAT32.

Can you boot from exFat or NTFS?
