Hi,

As I type I am creating my 4th Ubuntu USB flash drive. It's my 4th because the first three failed. What's odd is that they worked fine for a couple weeks each and then started to error out or things quit working (like network connection and software center). I have tried all recent versions of Ubuntu (12.04, 12.10, 11.10 ) and different flash drives (4- 8 GB PNY, Verbatum, Attache). They keep failing. Is it possible that running Ubuntu Live from the USB drive is too much for the drives? Too many writes? I use the drive for about 2 hours a day.
