Oh, forgot to mention since I forget some people use crappy windows which usually has flash drive using FAT32 or exFAT which has no journaling, thus more prone to corruption. You want to format it as NTFS on windows if you want maximum reliability. Though the downside is it will shorten the lifespan of the usb flash drive. But is less of a problem if you use an external SSD which tend to have larger TBW than most flash drives.

You almost always get an error when copying files via USB.  You can tell if you zip/rar up the file first so it has a stored CRC value that you can test later with programs like WinRAR.  When copying files via USB, "file is corrupt" is a frequent manifestation of the poor unreliable USB technology.

There is 0 reason why your data would be corrupt when transferring to a usb.

If anything, I can only think of 2 reasons.

1) When you write to a USB drive, the display is actually lying to you as it first loads up into cache to give the illusion of faster write speed. This is why if you try to do a unmount the usb, it will tell you to wait. You have to wait until the data is fully copied properly, then unmount. But many just unplug their usb and get corrupted stuff

2) You have one of those fake chinese usbs with looped storage. When you buy a USB, it may say 128gb on it, but in reality that usb is 32gb. The storage is looped so the first 32gb will load fine, but once you get past that, it will internally overwrite your previous data while keeping the index, essentially corrupting it.

3) Cheap faulty chinese controllers (though that applies to SSDs too)

4) Heat (again also applies to all storage)

5) Not powering your usb drive for 5-10+ years
