Re: Issue with MC 550E

There are many possible causes, but without more information it's hard to say. Is it all designs or just new ones? Will designs that you used before open? Are you getting error messages on the machine? Do they open in your computer? What software are you using to create or manage them?

There is also the possibility that the USB stick itself is worn out. The chemical process used to record data on a USB drive is good for 100,000 - 200,000 write operations. Writing is spread over the entire drive, so when one section goes bad, an alternate is assigned. Once all the alternates are gone, it's no longer possible to save data on the drive and you may not be able to open it. Typically this takes a few years to happen, but if you use it a lot it could happen sooner.
