Hello!  This thread is a dedicated thread for questions regarding which optical disc drives are compatible for dumping CDs to redump specifications. 

The most up-to-date list of which drives are eligible, can be found on the wiki: http://wiki.redump.org/index.php?title= … bility:_CD

The "New Dump & Verification Submissions" section includes drives that are confirmed eligible for both new discs and verifications.

The "Verification Submissions Only" section includes drives that are eligible for verifications, but not yet for new discs.  Over time and with continued testing and research, more drives may become eligible for new discs.  Please check the wiki page for the most current list.

As stated on the wiki, please remember, You must update the drives to the Required Firmware version and dump using Redumper build 610 or later (supported by MPF 3.3.2 or later).

If you have any questions about the updated lists, or whether your drive is eligible, please ask them here.  Thanks!

Q: I have an Asus / LG drive that is a JB8/JB9 drive and is eligible for cross-flashing to the custom ASUS BW-16D1HT firmware made by Ribshark.  Is this eligible for new discs?

A: YES.  For all intents and purposes, these drives (once flashed with the custom firmware) act just as the Asus BW-16D1HT eligible drives, and are thus eligible for new discs and verifications.  More information is found here: http://wiki.redump.org/index.php?title= … al_Details

Q: Are verifications (not new discs) of non-Audio CDs using DiscImageCreator and a good non-Plextor drive still allowed?

A: Verifications of non-audio CDs using DIC are only accepted if done with a known eligible Plextor drive.  Redumper (build 610 or later) is required for all other drives.  Redumper is still preferred and encouraged in all cases.

Q: The change in rules means that verifications of audio CDs are no longer restricted to good Plextor drives? Using only Redumper, of course.

A: Yes, Audio CDs can be verified with eligible non-plextor drives (as listed on the wiki: http://wiki.redump.org/index.php?title= … bility:_CD), if using Redumper build 610 or later.

I only have two questions:

1. Are verifications (not new discs) of non-Audio CDs using DiscImageCreator and a good non-Plextor drive still allowed?
2. The change in rules means that verifications of audio CDs are no longer restricted to good Plextor drives? Using only Redumper, of course.

Is there any good reason to phase out DIC like that on working drives?

Redumper has features that DIC lack. Also the former is in active development by a current Redump Moderator, while we aren't closely associated with DIC's creator anymore.

AFAIK DIC is also in active development, Sarami usually tries to fix things reported on github.
The features it lack should be related to extreme edge cases, otherwise there wouldn't be hundreds (thousands?) of discs that were dumped with DIC.
I don't have any issues with the fact that you guys prefer redumper over DIC, but only accepting verifications using DIC seems somewhat excessive. You're making it look like DIC has some sort of issue that makes its dumps faulty.

I think it is less about being associated with DIC or about active development, just that DIC does have three important differences with redumper:
1. Audio CD splits and write offset detection, which is why we only accept Audio CDs with redumper
2. There is a difference in how Redumper and DIC decide to descramble or not descramble certain invalid/unexpected data sectors. This only affects "edge cases", but it is important as some discs will not match redump hashes as a result (while the dump itself is fine, just post-processing is different). This is a design decision between the two programs, and we have decided to fix upon redumper's handling of it. DIC has changed how it handles different types of invalid/unexpected sectors over time.
3. For the new drives (Mediatek-based blu-ray drives), the leadout sectors are read using a cache read. DIC's current implementation of the cache read is prone to producing a bad dump, while redumper has fixed it (which is why these new drives have become acceptable for new dumps).

For Plextor dumps, DIC remains acceptable for dumps, with the above caveats. We therefore recommend using redumper as a "first step". In an ideal world, everyone could dump with both programs for self-verification, but we cannot force all dumpers to do this.
