I'm looking for a reliable way to check if an external or USB hard drive is functioning properly without needing to rely on Windows or Mac. Ideally, I want to know if there's a standalone program I can boot from a thumb drive to run diagnostics on these drives. Any suggestions?

You could use any live Linux distro. They often come with built-in tools for disk checking. Just load it from a USB drive and you should be able to run tests on your external drives.
Yeah, but make sure it has the right disk testing applications. I've noticed that some tools report drives as 'ok', but they don't give detailed statuses on all devices, so double-check the functionality of the tools before you rely on them.
