How do I rip successfully? (Not Accurate & Insecure)

[damian291]

I've tried searching in the forums for this but can't quite find a solution that matches my needs.

I'm currently ripping my CD collection and have so far completed 70+ CDs successfully. They have either all been in the Accurate database, or have ripped securely. I have come across three CDs however which are in the Accurate database, but I cannot match them. Nor can I get a secure rip. Everytime I rip (burst or secure mode) I get a different CRC. Additionally, there are always a random number of frames that are attepting to be re-ripped when I try in secure mode.

I have also tried with and without C2 error detection; Burst and secure modes and the following two different drives (with both having the same effects):

Drive 1: MATSHITA DVD-RAM UJ-850S ATA (Internal)
Drive 2: SAMSUNG TSSTcorp CD/DVDW SH-S182M USB (External)

Offsets appear to be set correctly as the other 70+ CDs rip fine and match the Accurate DB where applicable.

The CDs in question are:

Gorillaz: Demon Days
Avril Lavigne: Let Go
Sarah McLachlan: Afterglow

I can only assume it's some kind of copy protection as the CDs are in perfect condition.

I have tried listening to snippets of the rips and they sound fine, but how can I get a secure rip? They appear in Accurate (with at least 5) so some people are managing to rip these successfully.

Any suggestions are appreciated!

Thanks,
Damian.

CDs which look perfect can have manufacturing defects which effect certain drives.

Aha... that might well be it then. Thanks!
