Spin drive is still checked

Care to explain your rationale for this?

I was wondering about ripping some straight to .iso and worrying about some lesser used ones later, thats a but by bit copy and I can archive to DVD-R.

What do you hope to gain by doing this? You won't get a bit perfect copy with this method unless you have a combined read/write sample offset of 0 and I cannot think of a single program that will be able to generate such a format directly from CD that is secure. brian2090's post about image programs treating audio CDs as data discs is complete nonsense.

Ok, iso bad idea.

Here is the update with Spin Off, No C2 checked and Medium error checking:

Burst mode 4:46
Secure mode w/cache checked run in only copy tracks 8:12
Secure mode w/cache checked run in Test and Copy 16:14

So the question is, which one should I use? Is test and copy really needed with secure mode on?

Truthfully, I think I am fine in burst mode and its the fastest but I dont understand the difference from the secure mode.

Burst mode w/T&C if AccurateRip cannot verify.
For tracks where T&C CRCs don't match, rip in Secure mode.
Secure mode (no C2) w/T&C may reveal a problem, but there's probably nothing you can do at that point (configuration-wise) except tell the drive to rip at a lower speed; especially when EAC reports that the Copy was OK. Cleaning and/or buffing and polishing scratches can make a difference.

Here's a more detailed summary I wrote recently:
http://www.digital-inn.de/129988-post4.html

If your GDR8164B is compatible with the FUA command then I would recommend using Secure mode w/C2 with T&C if AR cannot verify.
http://www.hydrogenaudio.org/forums/index....mp;#entry539021
If the FUA command works, you will be able to uncheck the caching setting. When combined with C2 pointers, you will get burst-like speeds in secure mode.

Ok, Im starting to get it. I am reading as my little ones allow so let me see If I can sum this up:

Most of my Cds are not going to come up in Accurate rip. So Primarily I will use burst w T&C.

If I get a CD where the CRC's dont match, or there are errors I will use secure mode (right?)

I found a CD where one of the tracks is doing error detection (I know there is some scratches) That should be ripped in secure mode now correct?

The one thing that confuses me is the C2 option, I dont have it checked even though early on you recommended it. How can I know If I can trust the drive?

This is a log from burst mode, CRC's do not match on a bunch of tracks:

Anyway to speed up a FLAC rip?

Here is the log from a secure rip, although it says track 9 & 10 could not be copied they are there. C2 is still not checked. I do not have any CRC info for tracks 9 & 10 but all the others match now as opposed to Burst.

There were errors

End of status report

So basically, If C2 is checked and it reports the same errors I can trust it? At that point should I just do a test and copy anyway or is it pointless with C2 checked?

Here is something interesting, the 2 secure rips I did of this CD, one with C2 one without both did not make playable copies of track 9 & 10 however burst mode plays fine. The 2 secure rips left those 2 tracks as .wav files. The only problem is the Burst mode CRC's didnt match.

I did have error checking on high, should I lower that?

No tracks could be verified as accurate

There were errors

As much as I am starting to understand this, I dont get why burst mode was the only one able to make those files from a bum disk.

I found a CD where one of the tracks is doing error detection (I know there is some scratches) That should be ripped in secure mode now correct?

Not sure what you mean by error detection since burst mode really doesn't do error detection. This is why you use T&C and check for errors manually. If CRCs don't match and AR cannot verify, then yes, the best thing to do is switch to secure mode.

Quote from: JHFerry on 2008-01-12 16:56:25

The one thing that confuses me is the C2 option, I dont have it checked even though early on you recommended it. How can I know If I can trust the drive?

With the DAE Quality program as mentioned in the wiki. It's also possible to tell from trial and error: see if ripping without C2 is able to give matching CRCs in situations where ripping with C2 doesn't; especially in instances where the track quality is 100% for the C2 rip.

Quote from: JHFerry on 2008-01-12 17:36:32

Here is the log from a secure rip, although it says track 9 & 10 could not be copied they are there.

...and you'll find that they aren't complete. This is because you have EAC configured to skip extraction upon errors. Now it's possible (but not likely) for EAC to get the track right even though it reports errors and setting the Error Recovery Quality setting to High may improve the situation, but you'll have to let EAC continue ripping through errors before this can happen. In addition, allowing EAC to complete the track will give AR a chance to check it. This is yet another flaw in Eli's guide.

Quote from: JHFerry on 2008-01-12 17:36:32

I do not have any CRC info for tracks 9 & 10 but all the others match now as opposed to Burst.

Based on the information in the log for your burst rip, the only tracks you needed to re-rip in secure mode are tracks 9 and 10 since track 1 was shown to be accurate by AccurateRip. If you look at the Copy CRC for this track you'll see that it is the same between the two burst and secure logs: 802A5671.

Quote from: JHFerry on 2008-01-12 17:36:32

So basically, If C2 is checked and it reports the same errors I can trust it?

No. Drives with a C2 pointer implementation that does not work well with EAC will usually be able to report some errors; the problem is that EAC requires that they are able to report all errors.

Quote from: JHFerry on 2008-01-12 17:36:32

At that point should I just do a test and copy anyway or is it pointless with C2 checked?

I recommend T&C will all C2 rips. Taking this into account, I think C2 is a waste of time with drives that cache audio data but can't make proper use of the FUA command.

Quote from: JHFerry on 2008-01-12 17:36:32

I did have error checking on high, should I lower that?

I normally use medium, but it's up to you. I think the wiki is pretty clear on this.

Quote from: JHFerry on 2008-01-12 17:36:32

I also did check using the -usefua command on my drive ( I did it from a dos window and EAC popped up so I assume it ran the switch)

Here is the log, it did come up with errors:

The errors reported in the log cannot be used to determine whether the command works. You must look in the extraction dialog window for a "Read Error".

After looking at the header information in you logs, I recommend you configure EAC to use null samples for CRC calculations.

So basically, the goal is matching CRC's. Using C2 is for speed so If you want to be paranoid about the accuracy of the rip, dont use it. I was able to get through the Wiki tonight so hopefully I have a much better idea.

I forgot about that setting however Error recovery was already on high so my question is would I be better off unchecking the option to skip extraction and taking what the secure rip gives me in a file or just keep the burst one? The thing about the burst ones (once I checked the null option as you suggested) the CRCs dont match so In the worst case I can cancel the skip extraction just for those 2 tracks. Prior to the null option I wasnt getting CRC results at all with those 2 tracks.

Right but in most cases I wont be ripping the CD 3 times to compare to the correct secure rip. Especially If the CRCs match in Burst mode.

I dont get the whole FUA thing and Im not sure it worked. I tried it from a cmd prompt with the switch but EAC doesnt have any sort of way to let you know you are running in that mode.

If I run the EAC normally, and I take set the error correction to low, uncheck cache drive etc I get read and sync errors and it doesnt rip.

If I run it with the -usefua switch I just get a read error. Doesnt rip either. Does that mean it works?

The one thing you dont mention is the accurate stream feature, does that need to be unchecked?

Quote

Whats makes you say that?

BTW, I really appreciate all the help.

If you typed "eac.exe -usefua" (but without the quotes, of course) then EAC started with the switch.

This sounds like your drive doesn't cache audio data.

Ok, then based on this information, you won't be able to use the FUA command with either drive. One of the two non-Plextor drives that I have that apparently accepts the command causes EAC to hang as well, so I guess the behavior is not unusual.

Answering your other questions from the previous post...

So basically, the goal is matching CRC's.

The goal is a verified rip. You can verify one of two ways: AR or being able to get a consistent CRC, with AR being more conclusive of the two. If you've previously submitted results to the database for a particular disc and then ripped that disc again and got a matching result with a confidence of 1, then the AR result would not be more conclusive than getting a consistent CRC; it would be the same.

Quote

I'd keep the one with fewer audible errors.

Quote

The thing about the burst ones (once I checked the null option as you suggested) the CRCs dont match so In the worst case I can cancel the skip extraction just for those 2 tracks.

Although I wasn't explicit, the suggestion was actually to uncheck that setting.

Quote

I'd just hate to have you waste time re-ripping tracks that were ok. For this reason, I prefer to load a disc and first look for the AR logo at the lower left. If the logo is there then I'd rip by doing Shift+F5 and then check the AR results. You can always generate a second set of CRCs by pressing F8 if needed. If there's no AR logo then I'd just use Shift+F6.

Quote

The one thing you dont mention is the accurate stream feature, does that need to be unchecked?

No. So long as you can get matching CRCs and the no use of null samples is unchecked then the Accurate Stream feature setting can remain checked.

At what number of confidence can you trust AR though? I will be lucky to see any of my imports.

easy enough, If the medium file with errors sounds ok then thats good enough for me, If not I can try the high setting.

Actually, I did uncheck it so I got what you were saying.

Got it

So to sum up,

Most of my Cds are not going to come up in Accurate rip. So Primarily I will use burst w T&C.

If I get a CD where the CRC's dont match, or there are errors I will use secure mode

I have error recovery on medium unless I get a track that is stubborn then its pretty much playing around trying to get an accurate rip of the track.

Burst mode even with T&C give me decent speed but man did I learn alot. Reading the logs on a bad track does not mean I need to re-rip it all over. I can do a test read to compare CRC's in secure mode or even a T&C. The bottom line is you really only need to stray from Burst in my case if you have mix matched CRCs and/or errors.

I need to read about Cue sheets and ID3 tags, how should Flac be tagged, album art etc. Alot of my CDs are mixed so I need a good understanding of Cue sheets.

If it's not your submission, 1 is sufficient. If it is your submission then it is no less trustworthy than getting matching CRCs with EAC.

High and medium probably won't make a difference.

Unless it's an overreading problem, you're not going to see errors with matching CRCs in burst mode, but you have overreading disabled so it's a moot point. You might see "Timing problems" but with matching CRCs, these problems did not cause any errors.

Right, and you may want to throttle the extraction speed of the drive. Remember, if EAC gets through a track and doesn't report errors, it doesn't mean there weren't any regardless of the error recovery quality setting (though again, you run a greater risk of this happening when it's set to high and there are more than three sets of re-reads performed).

Quote from: JHFerry on 2008-01-14 20:46:27

Right, and I only recommended burst because your drive caches audio data. For drives that don't cache and provide C2, I recommend secure mode w/T&C and then try again without C2 if checksums don't match. With drives that don't cache and don't have C2, I would recommend secure without T&C, but maybe a test pass for tracks that required re-reads somewhere besides at the very very end of a track that couldn't be verified as accurate by AR.

The command line you're using with flac already includes the basic tags. The wiki should be able to help you understand cue sheets. The forum has a lot of discussions about more advanced tagging with most people recommending either Mp3tag or foobar2000.

You've come a long way, congratulations!
