The most common is that old FAT file system. For a test format one of your sticks to NTFS and if that's compatible you might see some improvement or the issue vanish.
But given all the malware out there, and other issues I see with folk that have different word processors that claim their files are ruined from machine to machine I think this issue will dog folk even if the files are fine.

From the time I started working with computers. I keep ruining diskettes (sm floppy) new or old, on various computers. Home or work, desktop or laptop, new or old computer. Now the same thing is happening with my flash/thumb drives- new or old, home or work computer, desktop or laptop. I have always been extremely careful while storing and transporting my disks/flash and make sure I safety stop before removing from the computer. I know people who do not take care of their devices and nothing ever happens to their files. I don't understand why I always have corrupt files. I keep thinking I am doing "something" wrong. Today someone posed this question to me: could I physically be putting off an electrical or magnetic discharge to be losing my files. Is this possible? I'm the only one that seems to have this problem and I treat things with care. Any tips or advice would be greatly appreciated. Thank you.
