You can disable the idle timer...not sure about the other problems. One of the 2 week old 3TB WD30EZRX drives I got already needs an RMA. It had a Current Pending Sector Count. After running DLGDiagv519 to analyze/fix the issue, it now has an Offline Uncorrectable Sector. I don't trust the drive now....got some Ultrastar drives coming. Maybe they'll fair better.
