FordGT90Concept download HD Tune... Best tool to check harddrive health. There is a lot of things you can do or try to make your hard drive quieter, but the best and usually the cheapest is get a new drive. That's if you value your time spent. Cooler Master makes a great HD cage http://www.newegg.com/Product/Product.aspx?Item=N82E16817993002. You can't beat the price either. I have it and its a great product. I have 3x WD 250 RAID0 (these drives where built for RAID not stand alone use. My read is Min 126.4MB/sec Max 172.7MB/sec... Not bad for 39.99 drives.) Using the "COOLER MASTER STB-3T4-E3-GP 4-in-3 Device Module Hardisk Cage" I never hear my drives.. but I do have 4x 80mm 3x 120mm plus my zalman 9700, and fans in my corsair 750TX.
