My cruzer appears to work - the lights blink on the drive when you try to access it. But it can't really find the files. Still says the drive ISN'T FORMATTED. Based on one post, I changed the drive letter away from the default F: to an unused letter. So far, so good. But... No matter what I have tried, when I format it in a variety of ways, the info window works up to 99% complete and then tells me it can't format the disk. But won't say Why... So I have an unformatted Cruzer.
