Yes, something similar happened today. I copied two movies into a volume on a drive accessed via Pogoplug and the copy seemed to run correctly. Some time later, however, the files appear to have simply disappeared from that drive and Pogoplug no long allows me to copy those files to that volume, apparently at any location. I was, however, able to access, edit, and resave a text file in the same folder where the movie files had been originally copied, so the issue appears to be specific to movie files. This evening I was able to copy a movie file into a different partition on the same Pogo-accessed drive. Once copied, the file seemed to behave normally. Will check tomorrow to see if it's still there.
