Bit 14 must be 1 and I have 0

I used the SSD Toolbox to check my drive and found what looks like a problem. Under Trusted Computing Feature Set Options: Bit 14 must be set to 1--and I have 0. What does that mean and how do I correct it?

According to ATA ACS spec, bit 14 must be set to 1 if the Trusted Computing feature set is enabled by bit 0 = 1. We don't support Trusted Computing feature set at this time(bit 0 = 0), so bit 14 is irrelevant. However, I do agree this is confusing wordage in the description and Intel will need to correct this description in future release for toolbox.

Thanks, I was going a little bananas over that wondering what it was and what I could about it. On another note, Windows 7 64-bit has Superfetch, Prefetch, and ReadyBoost enabled, and shouldn't they be disabled with SSD?

Check out this site:

Windows* 7 should be disabling them for SSD automatically - as long as SSD is reporting device ID info properly - but you'll also want to give the OS some idle time to process the SSD settings and turn off the processes.

I read that article and that's why I am surprised those options are enabled. How do you want me to check if my SSD is reporting the info correctly? By the way, I know how to disable Superfetch and PreFetch, but I don't see how to disable ReadyBoost.

I checked in Services (Local) and SuperFetch is set to Automatically. I can change that to Disabled, should I do that? I can also disable PreFetch but will probably get error/warning reporting in Windows log file,

Maybe I am looking at wrong. I see those services listed as Automatic in Services (local), and so I assume they are running. Should I disable them?

The experience I've had is Win 7 disabled those features automatically, but let me retry some things to see if my understanding is correct.
