I have a MacBook Pro M2 and I was transferring around 20GB of data to a USB drive. I stepped away for about an hour, and when I came back, my laptop had gone to sleep. My laptop's sleep mode was set to activate after 15 minutes, but the transfer was likely still ongoing. I want to know if putting my laptop to sleep during a file transfer has any impact on the integrity of those files on macOS since the USB drive is formatted as FAT32. Will it affect the transferred files even if everything looks fine?

If your Mac goes to sleep while transferring files, it could definitely interrupt the process. It’s always good to change your power settings so the laptop doesn’t go to sleep during important transfers. That way, you won't risk any glitches or issues with your files!
Shouldn’t be a problem. USB drives can usually handle pauses during transfers without a hitch. The bigger risk comes if your computer unexpectedly reboots; it might forget the transfer entirely. Just check the sizes and counts of your files on both the original location and the USB—make sure they match!
Nope, it should be fine. Your laptop just paused the transfer and picked up right where it left off when you woke it up. FAT32 isn't likely to corrupt just because your Mac took a little nap!
I can't speak for USB drives specifically, but I had a similar issue with uploading files to SharePoint. My transfers would stop whenever the computer went to sleep, and they wouldn't resume. The best move is to disable sleep while you're transferring to make sure everything goes smoothly.
You're good! The transfer just took a break and resumed after. FAT32 is reliable enough that it won't suddenly mess up because of a quick sleep break. Don’t sweat it!
