Query: Worked well at first

Mine worked fine at first, but I couldn't use it at home, because my Windows 98 didn't have the right drivers. I searched for them, and when I put the driver on my computer via a floppy disk, my USB drive decided to stop working. It didn't always work on the first try plugging it in to the USB slot (and sometimes took several tries before it died), but this time it was done. It wouldn't work at work anymore, too. I did notice a slight rattle when I shook it, so apparently it broke from the inside, but held up fine on the outside. It was in my front pants pocket just about every day for awhile, and the cap always stayed on, but it couldn't handle being moved around, I guess. Basically, I lost a lot of my data, because it wasn't all backed up on something else. These things are all risky, and make sure you have the important data stored somewhere else, so when it dies, it won't be a huge problem.
