Are the pre-gaps ripped and added to the tracks when ripping with the "copy selected tracks" option in EAC or are they just added when using "copy image & create cue sheet"? If they can be added to the tracks in "copy selected tracks" mode, do i have to press F4 to "detect gaps" for EAC to include them?

probably Feurio, yes, I don't know.

A pregap can be something different according to different people.
I think that officially, it is a hidden part before a session.

EAC calls "pregaps" the "gaps" of the tracks because CDRWin used a command called "pregap" to create them in the cuesheets.
They were 2 seconds long silences marked with indexes.
Nero and EasyCD creator call them "pauses".

Now, what EAC calls "pre-gaps" are the audio data at the end of tracks that are between the index marker 0 of next track, and the index 1 of next track (that marks the actual beginning of next track).

EAC is the only program I know that enables handling them, and I think it's the most confusing thing in this program after offsets.

When you don't detect gaps, EAC will work like any other ripper and copy all the audio data.

Problems begin when you detect gaps. EAC now handles them separately. It can append them to previous track, as should always be done, since they are the end of previous track.
It can append them to next track. I don't know the hell what for.
It can leave out them, cutting your tracks before they finish !

I don't know if I should say they are "useful". The data they contain are part of the CD, and often part of the music (classical recordings, live recordings...).
Their detection is seldom useful. The only case I heard of usefulness is if the gaps actually mark silence between separated tracks (not always the case), and if you want to rip MP3s from the copy, and use the leave out gaps option is order to have the MP3s of your playlist play right after each other with no silence between them.
It will always work from the original, but it will only work from the copy if you used the copy CD and create cuesheet action. Otherwise, the gaps won't be marked on the copy.

The gaps are always copied. If you don't detect them, they are copied all the same, they're just not marked.
