Hi, I am in the middle of extracting many cd's and have come to a standstill. I've just realized that Plextor Premium 2 drive can "Overread into Lead-In and Lead-Out." I have not not had that option enabled during this first phase of my year long extracting project. I have had "Fill up missing offset samples with silence" checked along with "No use of null samples for CRC calculations."

Here are my questions:

1) Should I now enable (check) "Overread into Lead-In and Lead-Out."

2) If I do enable (check) "Overread into Lead-In and Lead-Out," what if any changes should I make to "Fill up missing offset samples with silence" and "No use of null samples for CRC calculations?"

3) Any reason I should consider reextracting all the CD's I've done so far?

My EAC logs all show the following. Is the "null samples used in CRC" log setting below consistent with the setting I had enabled above?

"Overread into Lead-In and Lead-Out : No"
"Fill up missing offset samples with silence : Yes"
"Null samples used in CRC calculations : No"

Absolutely not.

Yes, and it will keep you from falling victim to a bug in EAC that sometimes repeats the last few non-null frames of the disc. This should be fixed in V0.99pb5.

Leave "Fill up missing offset samples with silence" checked. "No use of null samples for CRC calculations" isn't really related to overreading, but that setting should be unchecked.

Only if you are extremely anal-retentive. If you want to re-extract, you only need to re-extrack the last track (unless you're ripping as single-file images, of course).

This is all covered in the wiki:

ok, thanks.

I've unchecked "No use of null samples for CRC calculations?" and now my EAC log says "Null samples used in CRC calculations : Yes"

Is it me, or is the phrasing of the log file confusing when compared to the dialog box for that setting. I guess my real question here is that if the EAC log file now says "Null samples used in CRC calculations : Yes" I have things correct, right?

I don't think I'll be re-extracting, but what if that last track were "connected" to the track before it and so on back up to the first track on the disc (ex. a live album). wouldn't you end up needing to re-extract the whole disc?

Moderation: Fixed quotations.

It isn't if you take both each phrase (the one in the configuration and the one in the log) literally, but yes they are reversed from one another. It's usually better for a setting to tell the program to do something instead of not to do something.

That's right.

No. The lead-out occurs after the end of the last track, not between every track.

If you check overreading that makes "Fill up missing offset samples with silence" irrelevant, since no missing samples remains.

"Fill up missing offset samples with silence" is a global setting, which means that it will apply to all drives in a multi-drive system.

If you have a drive that cannot overread then you still want it enabled and doing so will cause no harm to rips performed by the drive that's configured to overread.

Pardon, I ignored that fact.

You did bring up a very valid and informative point which wasn't addressed in this discussion:

The filling up missing offset samples with silence setting does absolutely nothing when ripping with drives that are configured to overread.
