This is the message I just sent to Antec tech support, I was wondering what you guys thought about the situation: About a week ago, I had three hard drives in my Antec Sonata case. Recently my 160gb Western Digital SATA hard drive (WD1600) began to click to death and would not boot. I have requested an RMA on it. A few hours later, I noticed that my 80gb IBM Deskstar started acting funny. It became unreadable in the computer with the Antec power supply, but when put in another computer it can be read fine. The sole remaining hard drive (10gb IBM) is now not booting. I installed XP on the 10gb when my 160 died. Is it possible that the power supply is killing my hard drives? I can give you more information about the computer if you would like. I find it odd that 3 hard drives die in the past week. HIGHLY unlikely that "it was their time to go". I will be calling tech support if there is no response to this email within 2 days. Thanks for your help.

whats the 12v rail like?

A power supply that is too weak for the system can cause clicking hard drives. Especially if the 12V is weak.

Currently the power supply is outputting the following ranges: +3.3V = 3.20-3.28V +5V = 4.16-4.24V +12V = 12.03V (steady) It is a 380W power supply, I have calculated it and it seems that my computer should only be taking about 335W MAX. I don't think that is underpowered. That +5V looks low, what do you think? Keith

I tried using another power supply on the hard drives and they worked fine. Even the one I RMA'd worked. Bad power supply I guess... good job Antec.

Hi, I have a similar situation. I too have an antec sonata but I have 2 SATA Seagate 120Gbs in my system - neither of which are a system drive. They have disappeared from my os (i.e. from Windows explorer) on occasion - just before one disappears I hear this faint beeping sound. After it's gone I get a message balloon near the tray saying file write failure occured. When it happens it's like the hard drive lost power somehow. It was happening a lot more often until I plugged them into the power supply at a different connection. Usually only one of the two disappears but both drives are on the same power cable so I am wondering how only one and not both might lose power at a time. I'm pretty sure the beeping (as faint as it is) is coming from the drive that is about to disappear from the system. Still it could be a power supply issue. But I just don't understand how come both drives don't loose power when it happens. After reading your post I think it is time to investigate the Antec sonata power supply as a cause of this Thanks if you can provide any insight.
