I like Rod Smith's gdisk for GPT partitioning, more versatile in creating different partition types: can run on modern MS-Windows, Mac, Linux, and is in FreeBSD ports.

I wouldn't give up on a USB stick, unless it's physically broken as happened to me once, until trying it with Linux, one useful version being System Rescue CD (sysresccd.org).

I've had USB sticks, including a discontinued Kingston Data Traveler model, that were not readable/writable on NetBSD until a fix, then became not readable/writable on FreeBSD.

These USB sticks are OK with Linux (System Rescue CD), and you can even install and boot FreeDOS on one of these USB sticks.
