I have been through approximately 5 or 6 Western Digital hard drives in the past couple of years. They have all been covered under warranty so it has only cost me the price of shipping, but I am getting sick of the hassle. Is this common or is something wrong with my system. I have replaced everything at one time or another including the mobo, vid card, and power supply. I have a 550 watt ps and 4 hard drives in 2 mirror arrays. The rest of my specs are an Athlon 2500+, DFI LanParty2 mobo, 512MB of Crucial memory, a Geforce 4 video card. I can handle replacing the drives, I just wish there was an explanation for why they keep failing me. Maybe I just have bad luck. Please let me know if you have any ideas. Thanks
