Spread Spectrum Clocking

I have a 200 GB Hitachi HDD on my XPS M1330 notebook.
 
The Hitachi Feature Tool gives me the option to enable/disable spread spectrum clocking. Can anyone confirm whether the system supports SSC & whether it is a good idea to enable it or not?
 
Thanks.

From what I understand, it's best to leave it disabled.

Thanks for your reply. I intend to leave it disabled as I do not seem to be getting any interference problems & I don't want to risk affecting system performance. I'm not sure that this sytem supports it anyway.

Re: Spread Spectrum Clocking

This is my experience with a Dell Inspiron E1505 and a Western Digital WD5000LPCX hard-disk drive.

The computer has a SATA-I (1.5-Gb/s) interface; the WD5000LPCX is a SATA-III drive and defaults to 6 Gb/s. In its default configuration, the drive is not recognized by the computer. The drive has four jumper pins. According to the Western Digital Web site, jumpering pins 1 and 2 enables spread spectrum clocking. Maybe so. I found that with those pins jumpered, the drive is recognized by the computer, and everything works fine. I'm posting from that computer, with that drive installed, right now.
