Can I specify the truncate size?


Recommended Posts


I am burning an audio cd from mp3 files utilizing the write mode using the cue sheet.  I add files which take up more space than the CD can hold.  I am presented with the option to overburn or truncate just before burning.  I choose truncate.  However Imgburn seems to overburn anyway.

It is my understanding that truncate writes as much as the disc reports it will hold.  

Before I burn the disc, Imgburn reports the free space as: 736,960,512 bytes.  

After choosing truncate, the disc ends up with 759,498,752 bytes written to it.  I have tested this twice to ensure I was selecting truncate.

When I play my CD, at then end of the CD the player errors by continuously seeking (I hear the head continuously seeking).

My question is can I select or specify the truncate size to prevent this from happening?

My guess is I won't get a reply from this user given the age of the post. but I am curious as to whats the specific brand those CD-R's? ; because if they are Verbatim I am reasonably confident you can go to at least 82:14:66 (82min15sec) and have a successful overburn and music will play without the clicking issue you experienced at the end of the standard music CD-R as I noticed in the past when I overburn too far on other random CD-R's they react the same, at least in some of my CD players if I recall correctly. but the Verbatim (CMC Magnetics Corp) 80min CD-R I have are easily the furthest I overburned successfully as I would guesstimate on any random brand of CD-R's nowadays you can probably get at least 30sec to maybe a minute or so over the 80min mark, but much beyond that your rolling-the-dice and it could easily fail. so when I got 2min15sec over successfully I was a little surprised since prior to that happening I figured 1min15sec to 1min30sec was pushing it really hard on any random CD-R brand.

but if yours is Verbatim brand that probably means I am very close to the failure point (from my best guess without knowing the exact cut off point) as 82:14:66 works but your 82:26:49 fails, which probably means the overburn failure point is somewhere between 2min15sec to 2min26sec over the usual 80min normal limit. it's possible I could try pushing over the 2min15sec limit to maybe 2min20sec at some point in the future but I only burn standard Audio CD's occasionally and getting a CD-R to very close to say 2min20sec over the 80min limit might not always occur as I mainly use overburning so if I go a little over the 80min limit I don't have to remove any songs.

who knows, if I did not mind wasting a CD-R I could say try burning 2min30sec over the usual 80min limit (so about 82min30sec), and assuming it fails, I could probably put it into a CD player and watch the time on the last song and see at what seconds left in that song it fails and from there I should be able to get a very close estimate as to the true limit of it by subtracting the time difference of when it failed to where it should have finished and then be slightly conservative from there. so for example... say the song playing failed at the 82min23sec mark (as the CD player starts the clicking and gets out of whack), which if it was 82min30sec that means it would have failed with about 7 seconds to go on the last song before it stopped normally, which that probably means I would have to have it so it's even less than that for the CD-R to close etc from a rough guess so the CD player does not do the clicking issue and will stop like is normally expected in a normally functioning CD-R.

p.s. I never tried the truncate option though since in my case ill always either overburn (like if it's a bit past 80min) or make sure it will fit within the usual 80min limit by removing song(s).

I don't know the brand.  They were CD-R's I got from a thrift store with no branding on them, however Imgburn reported the manufacturer as "Manufacturer: CMC Magnetics Corp."  They came in a stack of 100 and are white, with no markings whatsoever.

So what I was saying does not really apply to you or you to me since yours are from a random manufacturer as they might only overburn a minute or so over the usual 80min limit, but it's hard to say for sure without testing as we only know you can't do '82:26:49'. because I imagine with the 'CMC Magnetics Corp' how far one can actually overburn will probably vary from manufacturer to manufacturer. so in that case only way I can know the rough cut off point of mine in particular is to waste a CD-R and say try burning 82minute30sec or more just to see if it works or not as if not as when playing I can get a rough idea of where the cut off point is.

but thanks for the info as I did not expect to get a reply given the age of this post and you only had one post until now ;)
