nstgc Posted December 23, 2011 Posted December 23, 2011 (edited) I am trying to make BD augmented with R02 ECC data created with DVDiseaster. I first made the ISO using ImgBrun, then made the augmented ISO, then I burned the augmented ISO to disk with ImgBurn. However, I followed this guide to checking to ensure the data was implemented properly and it wasn't. As a further check, the resulting ISO image (from the read step) is too small to have the extra ECC data that I thought was going to be on there. Does anyone know if or how to get it to work? [edit] Sorry, forgot the log file. ImgBurn.log Edited December 23, 2011 by nstgc
LIGHTNING UK! Posted December 23, 2011 Posted December 23, 2011 It has burnt and verified whatever you gave it... so if something is missing, it must be in the ISO itself.
nstgc Posted December 23, 2011 Author Posted December 23, 2011 (edited) It has burnt and verified whatever you gave it... so if something is missing, it must be in the ISO itself. What do you mean? Are you saying the ECC wasn't present in the original ISO I burned from? If that is what you are saying, I've already addressed that possibility in my opening post -- the size of the ISO I burned and the ISO I made from the burned disk don't match. [edit] The ISO I ripped from the BD I burned is about 1.5 GB smaller than the ISO to the disk. Edited December 23, 2011 by nstgc
LIGHTNING UK! Posted December 23, 2011 Posted December 23, 2011 What I'm saying is that if 'C:\Documents\steam-BU\12-23-11.ISO' is the augmented ISO and its size really is 24,125,872,128 bytes (check its properties in Explorer), all the data is present on the disc. Without watching what you do every step of the way, I can't possibly know if you've done everything correctly. If the ISO you've read back from that burnt disc (your log didn't include that step) isn't also 24,125,872,128 bytes in size, something is going wrong.
nstgc Posted December 23, 2011 Author Posted December 23, 2011 (edited) I checked the ISO, and it is the proper size. Also I ran DVDisaster's verification on the augmented ISO and DVDisaster detected the ECC data embedded into the ISO. [edit] I used DVDisaster to rip the disk since that's what the guide said to do. Also, from a physical examination of the disk, its clearly not filled. I'm currently ripping it with ImgBurn and will update this post with the log. [edit2] I attached the log file for the ripping. Also I checked the ISO created using ImgBurn, and it has the ECC (which is shocking). However, the ECC is wrong or something. ImgBurn2.log dvdisaster.log Edited December 24, 2011 by nstgc
LIGHTNING UK! Posted December 24, 2011 Posted December 24, 2011 You can expect anything up to an additional 31 sectors of data (well, padding) on a BD-R disc as the ECC block size is 32 on BD media (it's 16 on DVD media). This data (padding) is added by the drive. So if you only burn 1 sector, the drive will write 32. If you burn 33, the drive will write 64.

So you are saying that sort of "error" is normal, to be expected, and harmless?
LIGHTNING UK! Posted December 25, 2011 Posted December 25, 2011 Yes. It's actually mentioned on the dvdisaster page too. http://dvdisaster.net/en/howtos91.html Look under 'Possible error causes and remedy:' -> 'Typical problem: wrong image size.'

I'm satisfied. I haven't checked to make sure that's the case yet, but I'm sure it is (I'll still check later). [edit] I checked and it does indeed match once I prune the padding. Thank you again.
