You can use the mfg's drive tools to turn off the sleep functions on green drives in most cases so you don't have to ping the drive to keep it awake. FYI If you want to run a drive 24/7 for things like media files get a NAS style drive you'll pay maybe $10 more than a normal Desktop drive but you'll get better performance and some thing that is made to hold up in a 24/7 environment without paying for an Enterprise style drive, which are twice as much or more. I like both WD and Seagate but for a RAID I stay away from WD as they can be buggy in a RAID. Samsung and Deskstars are fine too but I would stay clear of the generic WL drives at least for now. I'm afraid ddp is right it is time for a new drive likely.
