I did use it quite a bit, I wouldn't have thought I was a heavy user but maybe I was!

I e-mailed Lexar Tech Support, let's see how far that gets!

Well the e-mail came back in less than 24hours, telling me how to get an RMA no. to return the product. We'll see where this goes !! .....

Flash memory does have a limit, but most of them are in the range of 100K-10M cycles. Unless you've had the drive for years and us it very regularly, I'd bet on defective vs. worn out.

Purchased in Dec. 2004, and not daily use. I would go a couple weeks without using it and then use it quite a bit for a few days (storing it properly, of course!) so definitely sounds like it was defective. It's on its way back with an RMA# so sounds like they are going to replace it!
