fdhdfhdfhdfh Posted December 3, 2009 Share Posted December 3, 2009 (edited) Hi, I created 3 ISOs with ImgBurn. I have 3 DVD Burner in my computer (Intel Q9300 | 8GBRAM | 4 X 1TB HDD | -> Good Computer) I need to burn 3 ISOS at the sametime. 1st ISO to 1st dvd burner 2nd ISO to 2nd dvd burner 3th ISO to 3th dvd burner It's work, but IT'S EXTREMELY SLOW. When I burn 2 things at the sametime it's fast, but 3 or more -> SLOW. Do I need to change something in ImgBurn... or anywhere else ? Thanks !

LIGHTNING UK! Posted December 3, 2009 Share Posted December 3, 2009 There shouldn't be an issue if each image is on a different hdd. All drives should be SATA (or SAS). IDE wouldn't work very well due to the whole Master/Slave thing where 2 drives share the same cable/channel on the controller. Link to comment Share on other sites More sharing options...

LIGHTNING UK! Posted December 4, 2009 Share Posted December 4, 2009 Random access would be killing it then. Link to comment Share on other sites More sharing options...
fdhdfhdfhdfh Posted December 4, 2009 Author Share Posted December 4, 2009 Random access would be killing it then. Ok, so what I need to do ?? Change Transfer Length / Buffer size ?? Change Buffer Recovery Thresholds ?? Desactivate Random Access ?? With 1 ISO --> Speed is around 7X With 2 ISO --> Speed is around 3X (each) With 3 ISO --> Speed is around 1X (each) thanks Link to comment Share on other sites More sharing options...
Cynthia Posted December 4, 2009 Share Posted December 4, 2009 Perhaps another hard disk? Link to comment Share on other sites More sharing options...
fdhdfhdfhdfh Posted December 4, 2009 Author Share Posted December 4, 2009 Perhaps another hard disk? It's a new hard drive... and my computer already have 4 HDD + 3 DVD Burner, so no more SATA port available. I'm sure we can change something in the buffer to optimize multiple burning ?

Cynthia Posted December 4, 2009 Share Posted December 4, 2009 Aha, you already have the ISO's on different hard disks. Sorry. Link to comment Share on other sites More sharing options...
fdhdfhdfhdfh Posted December 4, 2009 Author Share Posted December 4, 2009 Aha, you already have the ISO's on different hard disks. Sorry. All my ISOs are in the same HDD. I have, like 65 Computer Recovery disk (converted in ISO in my HDD). Each Computer has like 2 or 3 Recovery. If I need "1 computer" recovery, I need to burn 2-3 recovery at sametime. So, now you understand why I need ONLY 1 Hard Drive. I'm sure the problem isn't there also, read iso and transfert data into buffer should'nt take all HDD bandwith, no ?? I think imgburn is just not able to manage the software buffer of something like that... I'm right or not ?? What should I do ? Link to comment Share on other sites More sharing options...
LIGHTNING UK! Posted December 4, 2009 Share Posted December 4, 2009 You just can't read the same image from the same hdd 3 times simultaneously, period. Unless you buffer the entire thing, there's always going to be a point in time where your hdd simply can't keep up as 3 different programs attempt to read from it. It's not about hdd (or interface) bandwidth, it's about hdd physics. Link to comment Share on other sites More sharing options...

Now, i'm sure it's the HDD the problem... Can we set something like that in Imgburn : I start the 1st ISO (buffering),then he start burning -> second ISO is buffering, then he start burning (the first continue to burn), the 3th start buffering, then he start burning and the 1st start buffering (so everytime ONLY one ISO will do the buffering). THanks PS: I saw this post and they said "Ones" support multiple burning... did you test it ?? : http://forum.imgburn.com/index.php?showtopic=2022 Link to comment Share on other sites More sharing options...
LIGHTNING UK! Posted December 5, 2009 Share Posted December 5, 2009 If you start each one going and wait until the buffer is full before starting the next one, all you're doing is delaying the point where the hdd has to start streaming 3 lots of data - so you'll still get buffer issues. (i.e. it's a waste of time) If you want to burn to multiple drives with ImgBurn then you need a faster hdd setup (i.e. RAID) or you need the image on multiple hdd's. Hell, you could even get some more RAM and make a virtual hdd in memory - then copy the image to it and burn from there. If you want/need to stick with the image on 1 hdd, use a program the can actually burn to multiple devices from within a single instance (as you know, ImgBurn can't do that). It'll only read the image file once and then you won't have a problem. Link to comment Share on other sites More sharing options...
