I have a flash drive that I use a good bit, but recently it's started doing this thing where it won't eject. Even force ejects hang and I literally have to restart the computer to get the message to go away. It also has issues deleting files. Perfect example, I just plugged it in, dragged one file to the trash, didn't do anything else, and when I try to empty the trash it says that file is in use when it definitely is not. Then, giving up on that I try to eject the drive and it won't. I'd say it won't eject about 3/4 of the time. Other drives are fine, so it's not something I'm doing, and it does it on every computer I try, so it's not just my computer in particular. Any ideas what might be causing this? It's a Patriot brand if that helps. Not some cheapo or anything.
