Will not verify faster than burn speed.

[Relentence]

Using another CD recording program, I burned on ISO to a 4x CD-RW disc. The burn completed and then the program automatically verified the disc taking a couple of minutes. It reported the read speed on verify as 24x speed.

 

Using Imgburn 2.3.2.0, I burned another ISO to the same type of 4x CD-RW disc. The burn completed and then Imgburn automatically verified the disc at 4x speed taking almost 20 minutes.

can you post a log please?

[Relentence]

After I made the original post, I burned another CD to pay closer attention to what was going on. The verify took about 15 minutes. I found that for almost the entire verify, the rate was 4x. Then for the last ten seconds, the speed jumped up. The log is posted below. It includes creating an ISO image from an original, burning the ISO to disc and the automatic verify.

This might well be part by design, part not.

 

Go into the settings and look on the verify tab for the option about setting the read speed.

[Relentence]

"Set Read Speed" is unchecked and the grayed out "Read Speed" is listed as "MAX". All other boxes are unchecked except for "Enable SpeedRead DVD (Plextor)". These are probably the defaults.

Sorry, when I said 'look', I meant go and enable it.

 

Without that, the program doesn't issue any commands to set the read speed - i.e. it'll use whatever the drive defaults to.

 

I've made some changes in that department since 2.3.2.0 so the next version might be better for you anyway. That said, I don't recall seeing this issue myself when I burn CDs so maybe not all drives suffer in this way.
