I am running the 7100RC first of and I have the power saver for hard drives set to never power down. I am unclear what else could be causing this problem. Is there another setting somewhere that tells the drive to turn off? The problem is that I use this drive as a storage drive and also my DVR drive. it is disappearing/powering down during recording of TV shows. It happened 3 times last night but I have now been running for almost 2 hours and no problem and prior to this was running great for a few weeks straight. Unfortunately, I had this problem a few weeks back and instead of doing what I should have done…I panicked like a normal everyday user and formatted the drive and lost everything (except for the real important stuff backed up to DVDs) instead of just cycling power on my PC to get the drive back and going from there. I have since learned from that mistake but the problem has returned. Is it possibly a drive problem? The only thing is that I ran Vista x64 with no problems a couple of weeks ago(I had been running forever). I thought it might be some kind of IDE problem as well but the CD Burner is still available on that same controller/cable, which “should” mean it is not controller related but just to verify, if I get this problem again before anyone answers, I am gonna switch to the other controller and see what happens.
