Computer problem: Some help please?

I was just checking stuff on My Computer, when I saw this listed in the System Properties/Performance menu:

And

The following was in the Details box:

And

It says it may reduce the performance of my computer, but I haven’t noticed any lowered performance. This is also the first time this has ever happened to my computer.

Is there someone who can help me find out what is causing the problem and help me with a way to solve it (Other than formatting)?

Youre probably using a 16 bit file system & it wants a 32 bit system; but as you said, it don’t matter much.

Yeah, I’ve seen that a few times.

Normally, enabling 32-Bit Disk Access in the BIOS fixes it right up.

Sometimes, it doesn’t.
