RAID and Spread Spectrum Clocking (SSC)

[kjv1611]

I have a question which I'm hoping will be a pretty easy one for some of you guys here.

If I change the jumper settings from SSC enabled back to the default, (SSC disabled), then will that cause me to lose any data, or should I be safe in doing so - without reformatting?

If it depends upon the hardware, is there a way for me to verify this before making the change?

Any suggestions/information/links greatly appreciated.

Any thoughts? Anybody?

kjv1611,

Obviously not a hot topic...

I found this from a forum post in 2005:

Spread Spectrum Clocking is when the actual clock speed of an electronic device is purposely varied to prevent large amounts of EMI ElectroMagnetic Interference on a particular frequency.

Real terms - So a guy sits outside you house and revs his car to 3000rpm and holds it there. Pretty soon that continuous tone will drive you mad. If he were to 'Spectrum Spread' his car, he would slowly increase and decrease the revs, say from 2000 to 4000rpm. In my explanation at least, this would be less annoying.

PC Terms - Electronic devices these days must not produce excessive amounts on EMI on a particular frequency. Spectrum Spread technology is used to minimize the interference, by making it change all the time. Whether this is useful to the actual PC builder/user remains to be seen IMHO.

Thanks for the link. For now, I just added in the replacement hard drive, and enabled SSC, since that is what I had originally setup. Then I'll do another back-up of the data before trying to turn the SSC off again to see if it makes any difference.

The reason I was curious was that I was thinking that possibly the reason one of the drives went bad - or so the RAID controller said - was possibly just because of the SSC. Seems like a weird idea to me, but I was hoping to be able to verify with someone one way or the other.

But from what you posted, and what little otherwise I could find, it sounds like it really shouldn't make any difference as far as for performance and stability. I don't know....
