Ripping errors under EAC Secure Mode. What can I do?

[Jubei]

What can I do if I get ripping errors reported to me by Accurate Rip via EAC Secure Mode? The CRCs match, but Accurate Rip says otherwise according to their database. I tried ripping twice with same results.

I suppose my question is if I have only one disc drive, and EAC rips the CD with errors, what are my options?

There's nothing wrong. You just have a different pressing of the CD. The problem with the current AccurateRip implementation is that it assumes there is only one pressing of each CD. I'm sure this will change with the next version of AccurateRip, but until then, some CDs will rip fine but not match AccurateRip.

Ok. I wasn't clear enough. CD in question is Jeff Beck's Blow By Blow. 4 tracks ripped OK, 5 with errors. When it is a different pressing, all the tracks' CRCs don't match the ones in their database. So, I think I have a problem. The last track of a few of my CDs (esp. older discs) also tends to be ripped with errors according to Accurate Rip on this drive.

Listening to the tracks now . . . don't seem to hear any problems . . yet . . .

What's the condition of the CD? Any warping or scratches?

 

[Jubei]

CD is in OK condition. It is not brand new, I bought it back in 1991. Definitely no scratches and as far as I can see, no warping either.

Yes, you're right. You could try ripping in burst mode and *always* using test+copy; some people argue this is better than secure mode anyway. Beyond that, your only real option is to get a different drive.

That's because your drive doesn't reliably support reading into the lead-out. There's not a lot you can do about it, unfortunately, except moving to a different drive.

Its common for last tracks to have problems, especially if they are towards the outer rim of the disk and the disc is worn. If the last track is deep inside, it might be a manufacturing or pressing defect. I have noticed that EAC has a bad time right at the end of the last track in many of my CDs.

Also, I have theory that some different pressings may be 90% similar to another pressing which may lead to the wrong conclusion that the disc is bad, but its actually just a different pressing. I have a feeling many reprints possess such properties. I don't know anything about the details of printings, so all of this is based on my conjectures.

Thanks for all the input.

Wodgy: I normally rip in Burst mode first. If Accurate Rip says I have problems or if Test & Copy CRCs don't match, then I redo in Secure mode. The Lite-On drive I have is damn slow with Secure, so I more or less use Burst mode most of the time. I sort of suspected the solution would be getting a different drive.

Pedxing: alot of what I rip doesn't match what's on the Accurate Rip database as many of the CDs are Asian / local pressings, especially for more mainstream artists.

Use burst mode as much as possible - it decreases wear and tear.

I don't know if this is causing you grief, but sometimes liteon smartx feature takes over and causes EAC to rip at 2x-4x speed. This seems to happen to me almost 100% of the time when I turn on EAC's secure mode. Nero's CDSpeed (which is free) can temporarily deactivate the smartx feature by running the speed test for several seconds. EAC can then securely rip the CD at much faster rates. I have to do this each time I rip.

I have similar issues with accurate rip database too because I buy imports too. I be lucky if I find 3 or more users with the same CRCs.

You could always just download a FLAC copy of the album. Slower but since you own the CD, it would be legal.

 

[ChaseD13]

ehh it isnt legal (not if you use bittorrent where you generally upload as well as download, which is the only way i know that you can download flac files).

A lot of FLAC stuff gets posted to Usenet. I have rescued a couple of old CDs which no longer rip 100% that way. Some CDs are 20 years old now, and I have noticed that ones made around 1991 seem to be particularly bad.

If you can determine which tracks the problems are on, you can download only the ones you need. It's a shame EAC does not tell you how many samples had errors - to be honest one or two samples interpolated is not enough to really worry me.
