Many, many people assume them not being able to access an external drive means their data is lost, and they throw away a perfectly good HD in an external enclosure that has failed. This happens a lot, and they often get bad advice about it when asking on forums and that doesn't help. If they had removed the drive and simply placed it another enclosure they would have been right as rain. Before you write this HD off, remove the hard drive from the enclosure, and put it in a PC and test it. Now this voids the warranty, but if the data(movies) means more than the money, you should try this.
Of course troubleshoot the normal drive mounting issues on the OS first, before doing this. Like checking in Disc Management, checking event logs and look for drive errors, etc. Since you know you had USB issues you should check into the possibilities of the OS first. Try booting into safe mode too, see if the external is visible.
Also check the manufacturer's website for the meaning of the pulsing light on the front.
