Hi Pat, I have quite a few Lexar flash drives and I recommend them to clients. I find them excellent and have never had a fault with any of them. What you have described happened to you I would surmise, was using the software that some of mainly the older Lexars had on the flash drive.
I always check a flash drive; and reformat them in Disk Utility, which deletes any 'software' that might be on the flash drive. Then you know that nothing is incompatible on that drive that will cause problems.
