Rip process - worth making disc image first?

OK, I am relatively new to ripping discs in a sane manner. Previously, I would find the easiest to use software to pop a disc in the drive and let it do its thing to make lossy tracks.

Now, I am much more worried about quality than I am anything else, b/c in the end, HD space is cheap, and I want to be able to recreate my discs without having to go out and buy them again if I am faced with another house fire as I was a while back.

I'm currently (as we speak) ripping my (moderately scratched) version of The Crystal Method's Tweekend disc. Now, here is where it gets interesting.

I have Daemon Tools Pro Advanced installed on my system, primarily b/c I bought it when it first became available and the lifetime license price was ridiculously low (actually, I have *2* licenses - the second license was like 8 Euros additional tongue.gif), and secondarily b/c it has 3 different types of drive emulations built in. I've got a single physical BD-RW (LG BH10LS30) and also a single emulated drive from DT - a SCSI emulated drive.

I used DT to make an .ISO of Tweekend first, which I then mounted in the DT virtual drive, and let EAC extract and encode. I verified the log file at http://eachelper.atwebpages.com/Analyze.php and it reported 100% verified, but in scanning the log, I see that the CTDB plugin section of the log shows two files, tracks 9 and 11, with issues compared to the CTDB - which makes sense, when making the ISO there were probably data missing from the scratched sections.

I'm now trying the CD directly, and EAC is indicating that it is going to take (currently) >10 hours to extract 0_o

So, I remember reading in another thread (and forgive me for not linking to it - but I have read literally hundreds of threads in the last week, for various reason....) that ISO is not a good image to make b/c it is not a 1:1 image of the disc. I realize that EAC is attempting to accomplish that with native error checking, but I *also* realize that DT is *also* supposed to make 1:1 images of discs (more for the fact that people want to archive game discs in order to preserve the original / make the install process much faster (magnetic is faster than optical, and SSDs are faster than both, so mounting an image in DT on an SSD will fly through an installation much faster than placing the disc in an optical drive, even modern ones).

By now my EAC is reporting over 15 hours for this one disc sad.gif

So, my question is: provided I can get decent 1:1 images in whichever format I can (I think in DT I have the options to make .ISO, .MDX, or .MDS/.MDF, or an APE audio image), would it be prudent on my part to make images of my remaining discs and then use EAC on the images mounted in DT to save a (potential) boatload of time?

And here is a bit of shenanigans that the analyzer pulled on me after analyzing the log (I suspect is has to do with the CTDB additions to the log?)

By ripping from a disc image, EAC will be the same as any unsecure ripper (such as iTunes), only by reading the physical disc can EAC retry to detect and possibly fix errors.

I assume you mean for this specific case. Otherwise, let's not forget that EAC can use the CTDB plugin which can detect errors from a mounted image against the database and possibly fix them.

I was afraid of that. Some of my more scratched discs will simply not be worth taking the time to rip then, unless I purchase new ones.

*sigh*

One thing to note- I was mistaken - I did not rip to ISO, I ripped to MDS/MDF.

It doesn't really matter which image format you ripped it to, because it's a one-try readout vs. a secure ripper reading multiple time and taking the result that wins the majority vote. As for scratched CDs, there used to be repairing kits (sandpaper+polishing paste), that did wonders to several of my scratched CDs. Though beware of those cheap hand-driven all-in-one polishing devices, I lost a CD to one of them - it just scratched the whole CD instead of polishing it as advertised.

If that's too much effort for you, then buying another one should be a better solution.

That sounds interesting. I need to look into this a bit more....

If you can't hear a flaw when listening to the tracks that don't match the online database, does it really matter?
