Perhaps you should explain this a bit better, I know a little about PCs and I don't understand the question. Maybe you and they know more than me in which case excuse my ignorance.

Ah,
you mean cluster size?
Vegas knows nothing about it. In general though for video as they're large files go for larger sizes. This reduces fragmentation at the expense of optimum usage of disk space.

In my experience, the most common cause of "black frames" is one clip not butted against the other. In other words, a small (1 frame) of space between clips.
If we're talking about NTFS then 512 seems awfully small, particularly if you're working with large video files. There is nothing to be gained from having such small clusters. Personally, I leave it at the default 4096.

I agree with this as it is my experience too. The best way to catch this is to either expand the timeline and/or scrub through the whole video at about half speed.
