Query: Locked up after two weeks!

I have always used PNY. I have never had a problem with PNY, but this guy just seems to be a dud! After about a week of use, the the drive kept becoming "unavailable" from my list of available drives on my computer. While I found this annoying, I would simply unplug it and plug it back in to have it re-register itself. However, after about two weeks of use, the drive became write-protected (there's not switch to fix this issue) and I could no longer copy data to the drive. I almost didn't get my data back OFF the drive as well! As I was copying off my data, I had to sit in front of it and hit "cancel" on the "write protect" alert box. It took nearly two hours to move approximately 8GB worth of data. The only way to fix a write protected drive is to FORMAT IT and I couldn't even do that without errors! Unfortunately, I probably will NOT purchase a PNY again!
