I've been using restore media for years now to help fix my work related issues with videos/media all over the place! It works flawlessly every time (and it's free too!).
Honestly there are not many things about this product i dislike at least thus far. We're currently working through some software updates but they should be fairly quick fixes once those roll out in Q3-Q4 timeframe - very important considering how easy these problems can cause serious damage if left unattended! Not only does their team have great support when you need them via live chat OR email / phone calls; however, restoring your data from backups takes just seconds even after being stored offsite by other companies like Amazon S3 etc which makes sense since we don't store any original footage here anyway so no loss really!!
