Exact Audio Copy >EAC & LAME Quickstart >


So you managed to setup Exact Audio Copy and now want to share your settings with other users. Well, you've made it to the right place! This page will help you collecting all information needed for the User Reported Drive Features Database. Of course you don't need to provide all required information as some items may be difficult to determine or take a lot of time. But just try to submit as much as possible information... I've spend many hours (understatement) in creating this EAC tutorial, so please be gentle and take some time too to help other users who may not be as fortunate as you and were not able to determine some settings. If you have followed the EAC tutorial step by step you'll already gathered most of the information wanted.

Another goal of the User Reported Drive Features Database is creating an overview of drives so it's easier to see which drives are suited best for EAC.

Mail this information to The Coaster Factory. Thanks in advance!



This doesn't need much explanation I think. Just specify the brand of your drive. For example Plextor. If you know the website of the manufacturer you may also submit it.


The drive model and speed rating. For example: CD-R PlexWriter 8/20 (PX-R820T), where CD-R means that the drive is a CD-writer, PlexWriter the model or name of the drive, 8/20 the speed rating meaning 8x writing and 20x reading speed and PX-R820T the type number. The name or speed rating is often printed on the tray or front of the drive, or can at least be found in the manual or on the box the drive came in. Note that not every drive has a name. But obviously, all drives have a speed rating of course. The type number is displayed in EAC in the top left drop down box. The type number of the PlexWriter 8/20 is thus PLEXTOR CD-R PX-R820T. Please, also specify whether the drive is a CD-ROM, DVD, CD-R (CD-writer) or CD-RW (CD-rewriter).

Firmware Revision

The firmware of a drive can be compared with the BIOS of a motherboard. It's a small piece of software in a chip that controls the hardware. Most modern drives have a flashable firmware. This means the firmware can be updated by simply running the flash update program. Updated firmware versions often improve performance, add new features or fix bugs of the previous firmware.

EAC does not display the firmware revision so we'll use a third party tool for that: CDR Identifier. Download this small freeware tool. CDR Identifier is meant to retrieve the actual manufacturer of a CD-R disc, but it also displays the firmware revision of the drives in your system.

The left screenshot shows CDR Identifier. The third column Revision in the top list box displays the firmware revision. In our example the PlexWriter 8/20 has firmware revision 1.07.

Accurate Stream

Make sure you select correct drive from the top left drop down box in Exact Audio Copy and select Drive Options... from the EAC menu  or press F10. On the Extraction Method tab you can find the needed information. Of course, the information is only correct if you did the EAC Drive Configuration. Sometimes the Drive has 'Accurate Stream' feature may be checked but grayed out (when Drive is capable of retrieving C2 error information is enabled). In this case still report Yes for Accurate Stream. 

Audio Caching

See the setting of Drive caches audio data.

C2 Error Retrieval

See the setting of Drive is capable of retrieving C2 error information.

Read Command

The Read Command can be found on the Drive tab. Again, this information is only correct if you properly did the EAC Drive Configuration.

If your drive needs any of the advanced options on that tab for correct audio extraction you may report that too.

Read Offset Correction

The read offset correction can be found on the Offset / Speed tab. Note that the combined read/write offset correction is not usable since it only applies to your reader/writer combination. Make sure you have read Determining The Offsets carefully. Another interesting read is The Truth About Offsets. Many people report an incorrect offset because they do not really know what they have determined.

Overreading into Lead-In and Lead-Out

Also something you should read Determining The Offsets and The Truth About Offsets for. In the Determining The Offsets tutorial is explained into detail how you can detect the overreading capabilities of your drive. Specify whether the drive is able to overread into the Lead-In (I), Lead-Out (O) or both (I/O).

Read CD-TEXT Information

CD-TEXT is extra data written on an audio CD containing CD title, track title and artist information. Certain drives can retrieve CD-TEXT information. Exact Audio Copy is not able to auto detect this, thus you'll have to lookup the drive's manual or manufacturer's website.

Gap/Index Retrieval Method

This can be found on the Gap Detection tab. Like with most of EAC's options it's only correct if you followed Configuring Gap Detection.

Gap Detection Accuracy

Can also be found on the same Gap Detection tab.

EAC Write

Is the drive able to write with EAC? Not every CD-writer is already supported. Read the Detecting The Write Features tutorial to find out whether or not your CD-writer is able to record with EAC. This is of course not applicable for CD-ROM or DVD drives so report n/a if your drive is not a recorder.

Write Offset

The write offset is detected in the Determining The Offsets Part II article.


See Detecting The Write Features.

Write CD-TEXT Information

See Detecting The Write Features.

Average EAC Reading Speed

This is a rather easy test, but it may be time consuming if you have a slower drive. The goal is to get the average reading speed so people considering a new drive can see in the User Reported Drive Features Database what drives are fast and which are not.

To perform the test you need a CD with as close to 74 minutes audio on as possible. Then extract the whole CD to your harddisk as an image by choosing Copy Range... (not Copy Image & Create CUE Sheet... to avoid the time consuming gap detection process) from the Action menu or pressing F7. After the extraction finished write down the Speed displayed on the Extracting Audio Data dialog window below the progress bar. Make sure you use a clean pressed CD because rereads due to read errors may noticeable drop the extraction speed.

Overwriting into Lead-In and Lead-Out

This may not be confused with overburning! For more information about overwriting into Lead-In and Lead-Out read The Truth About Offsets.

At this moment I haven't found a 100% secure method to determine the overwriting.
