I just started a project to re-rip my CD collection in FLAC. I've got a new PC and installed and configured EAC with FLAC and am ready to go.
Everything is working fine EXCEPT, I am only getting 4X ripping speed. This means that eah CD is taking about 10 to 12 minutes to rip.
Is there a way to increase this ripping speed but not compromise the accuracy? I would like to see it at 12-16X is my gut feeling, but of course accuracy is way more important to me than speed when it comes down to it. Any advice would be appreciated!

Full Version: EAC ripping - slow drive speed
Without addressing some type of configuration problem, use Burst mode with Test & Copy (F6).
Re-rip any tracks that don't give matching Read and Test CRCs in Secure mode with features as detected by EAC except without C2 error reporting.
Regardless of the speed, I believe this scenario guarantees the best accuracy in the majority of circumstances.
About your slow speed:
Assuming that your config is ok, 4x is not all that unreasonable to see. It depends on the drive.

While it may generate a lot of controversy, reading through a few threads here will let you see that many people recommend Burst mode, using Test and Copy, rather than Secure mode. I won't enter into the debate about accuracy except to say that wherever the CRC checksums match (which is almost always), everything I've listened to after extraction to hard drive has sounded very good. The extraction rate on my drive is almost 10X faster in Burst mode, so that even with the extra Test step, things move along much better.
I have a new Lite-On drive and an older Plextor. For convenience I have been extracting with the Lite-On set up for Burst Mode and the Plextor set-up for Secure mode. For those infrequent tacks with problems, I move the disk from the Lite-On to the Plextor, where everything was resolved -- until lately.
I recently extracted a very difficult 13 disk audio book (supposedly brand new). Every disk had several or more tracks that did not work very well. Those tracks with mismatched CRC checksums had severe problems: many large clicks and frequent missing segments. The last track, and frequently the one or two immediately preceding it, were total loses from every disk. Extraction slowed to 0.1X and the data recovered was quite useless. After a while I just told EAC to skip the track when those symptoms appeared.
Trying the disks on the Plextor in Secure mode was no better. The bad tracks started off extremely slowly and got worse. EAC said it was operating at 0.1X but I not sure it was always doing anything at all.
The Plextor came with the application suite Plextor Manager 2000. One of its applications is Audio Capture 2000, which is a DAE program. It has no controls or settings except an "Error Correction" slider that goes from 0% to 100%. The only documentation is that higher error correction assures greater accuracy but operates at a lower speed. I've never used it except at 100%. Extraction speed often approaches the drive's maximum 40X.
Anyway, trying this application on the bad tracks gave me apparently perfect extraction on every one. Speed was only 3X to 4X on the worse tracks (although much faster on some tracks), but that is a lot better than 0X. The program provides no report but listening to the tracks, and visually scanning them in CoolEdit, gave no hint of any problems.
Comparing Audio Capture 2000 (at the 100% error correction setting) against EAC in Burst mode (simple Copy rather than Test and Copy) on a number of good condition music CDs always found EAC taking longer. I've never heard anything to complain about on albums extracted with Audio Capture 2000, although the reporting information from EAC is nice to have. Of course, one supposedly needs a Plextor drive to use it, but it seems happy enough operating the Lite-On.
Not only is Audio Capture 2000 cooperative about extracting from the Lite-On drive, the results always sound good.

I am not using an after market drive, but rather the drive that came with the Dell XPS PC. I will check the drive itself when I get home to confirm its specs. I assumed it ought to be reasonably fast as it is the latest that Dell puts in their midrange PC's...(that assumtopn might be my first mistake!)
I also was looking at Accurate Rip software which works with EAC and using known CD's does some kind of calibration. I don't know that much about it.
I guess I'll look through the forums a bit and see what info I can find about burst mode, but judging from the posts above, that will probably get me thoroughly confused. All that aside, if 4X is not too far off the mark in terms of performance, I guess I can live with it. (This will be awhile as I have about 2500 cds to rip)

I always find any laptop drive slower than its desktop equivalent, despite its speed. Plus they are less robust, and prob more likly to fail sooner due to heat. I'd recommend getting a cheap 5.25 inch external and a caddy for cheap.
I can rip ~25x secure on my desktop drive.

FWIW, I agree with AndyH-ha's point of view and way of doing things.
I'm not familiar with Audio Capture 2000, but I am with PlexTools Professional and I use it the same way: as a trustworthy alternative to EAC, though I wouldn't be trusting it if I wasn't also using a Plextor with a Sanyo chip and I still rip twice and compare results using some type of CRC checking such as sfv or md5.

Actually the XPS 400 is a desktop, not a laptop. It came with dual optical drives (DVD RW and DVD ROM - both rated at 16X).
I'll Give AndyH suggestions a try and see what happens.

You can always use Test & Copy in Burst mode, and then rerip tracks that don't match CRCs in Secure mode. Would be faster that way, and probably just as secure, if not moreso.
ah, i didn't realise it was a dektop, doh!
Even quicker would be just burst mode, no test and copy at all. instead setup eac with accuraterip. That way, you'll get fast speeds, verification, and also help populate the db more. For those cd's that aren't in accuraterip, simplu do a t+c for your own verification

I switched the setting to burst mode and it immediately went to 10X plus! THanks for your help everyone!
I am going to try AccurateRip next for the CRC comparison.
Now the only issue I am running into has to do with trying to rip CDs that were burned/copied. The drive slows to almost 0X on some songs. Are there any settings I should check that might be different for burned disks as opposed to retail versions? I guess this might be related to the above posts whereby another ripping program might not encounter the same problems as EAC?

Make sure you choose test & copy when choosing the extraction method, because burst mode alone isn't sufficient.
Thanks for pointing that out Firon. I just went through each of the options pages (EAC, Drive, and compression) but was unable to find where to check T&C. The choice for burst is only that. I must be missing something, but where can I select the T&C setting??
Edit: OK, I see that it is not a setting, but you choose it upon extraction...silly me <sheepishly>

Aye, Test & Copy Selected tracks under Action.

...or F6.If you are interested in saving time, do what kritip suggested. Rip in Burst mode by pressing F5 and check the AccurateRip results. If it can't verify the results as being accurate, test the tracks that are in qustion by pressing F8. For the checksums don't match switch over to Secure and press F6.
It's probably pretty clear that I'm a proponent of Burst T&C (either with F6, or F5 followed by F8), but I've been trying to think about this as critically as I can. Considering that comparing CRCs is not the same as doing a bit for bit comparison, I don't believe that I would be right in referring to this process as secure.
As naive as some may suggest, I still feel comfortable putting my faith in a number that contains no more information than what is used to represent 1/44,100 of a second of CD audio data.
When EAC reads a sector twice in secure mode and compares them, is it doing a bit or checksum comparison? The EAC homepage uses the phrase identical so can we assume this is a bit for bit comparison?

The chance of the CRC-32 algorithm failing is pretty neglible compared to the chance of getting matching CRCs on a bad rip because of consistent errors...
AndyH-HA, Plextor Manager 2000 is obsolete and has long been superceded by PlexTools Pro.
