shojisuka Posted July 18, 2006 Posted July 18, 2006 I was wondering if imgburn can do udf isos, like the ones from nero, so that i can burn files larger than 2GB.
LIGHTNING UK! Posted July 18, 2006 Posted July 18, 2006 Hard to tell what you're talking about here exactly... ImgBurn can BURN/WRITE images of any size really - depending on the size of your blank media of course! The next version of ImgBurn (version 2) can BUILD images from files on your hdd... yes it can do UDF only, and will allow you to create big images by splitting them (if needed) on FAT32 drives etc.
shojisuka Posted July 19, 2006 Author Posted July 19, 2006 Hi thanks for replying. I can't quite parse your sentence. Yes what i meant was if it can burn into a DVD, files larger than 2GB because supposedly iso9660 isn't specced for that. So do you mean that the current version of imgburn can burn single files larger than 2GB?
cornholio7 Posted July 19, 2006 Posted July 19, 2006 you should be able to build a file up to 4gb using iso9660 and imgburn will burn it
Darkfalz Posted July 19, 2006 Posted July 19, 2006 Nope, ISO9660 only supports a max of 2GB. Unfortunately the majority of UDF building programs are bugged (some support only 1GB max, ie. CDRWin).
LIGHTNING UK! Posted July 19, 2006 Posted July 19, 2006 Why would it be 2gb only? As far as I can remember, you're allowed to use 32bits for the file size, meaning 4GB is the largest. I certainly impose no 2GB limit.
Darkfalz Posted July 20, 2006 Posted July 20, 2006 Why would it be 2gb only? As far as I can remember, you're allowed to use 32bits for the file size, meaning 4GB is the largest. I certainly impose no 2GB limit. Because it's 32bit signed integer. Any greater than 2GB would give a negative number. I would have thought that would be obvious to someone like you.
LIGHTNING UK! Posted July 20, 2006 Posted July 20, 2006 Well yeah duh, it would be, but who says it's a 32bit signed integer?! I can see no mention of that anywhere. In fact, ECMA 119 specifically says the field, 9.1.4 - 'Data Length', is to be recorded according to 7.3.3 - 32bit numerical value. 7.3.3 - 32bit numerical value is defined as: 7.3.3 Both-byte orders A numerical value represented by the hexadecimal representation (st uv wx yz) shall be recorded in an eight-byte field as (yz wx uv st st uv wx yz). NOTE 14 For example, the decimal number 305419896 has (12 34 56 78) as its hexadecimal representation and is recorded as (78 56 34 12 12 34 56 78). Only for an 8bit field does it mention the word 'signed' or 'unsigned' - and they're the only 2 mentions of 'signed' in the entire document. So.... if you can tell me where you read it's a 32bit signed integer value (which, let's face it, would be pretty silly for a field they know would only hold a positive value!), I'd really like to see it for myself. (EDIT: Also, WinRar, IsoBuster, Windows 95 and Windows XP can all read ISO's with files > 2GB within them and report the full size correctly.)
cornholio7 Posted July 20, 2006 Posted July 20, 2006 if 4gb didn't work , why would a company as big as HP post a warning such as this?? NOTE: The limitation of 4GB for the size of a file is a limitation in the ISO9660 standard, therefore not a restriction imposed by HP-UX. source: http://docs.hp.com/en/B2355-90970/ch08s04.html
lfcrule1972 Posted July 20, 2006 Posted July 20, 2006 Thanks for reading around and clearing this up corn - nice to know that LUK! knows what he is talking about.....
kevdriver Posted July 20, 2006 Posted July 20, 2006 Thanks for reading around and clearing this up corn - nice to know that LUK! knows what he is talking about..... lfc, Never any doubt mate................
Kenadjian Posted July 20, 2006 Posted July 20, 2006 Thanks for reading around and clearing this up corn - nice to know that LUK! knows what he is talking about..... Well, yeah, DUH
cornholio7 Posted July 26, 2006 Posted July 26, 2006 i have just proven to myself that this works by making one big file over 2gb and converting it to iso heres the file heres the log I 20:47:22 Image Sectors: 1.545.112 I 20:47:22 Image Size: 3.164.389.376 bytes I 20:47:22 Image Single Layer Profile: DVD-R/RW (Media Capacity: 2.298.496) I 20:47:22 Image File System(s): ISO9660 I 20:47:22 Destination File: I:DVD ISO\vob iso.iso and heres the greater than 2gb iso i hope this clears up any doubt
lfcrule1972 Posted July 27, 2006 Posted July 27, 2006 I was never in any mate but sometimes hard proof works above anything else !
Darkfalz Posted July 28, 2006 Posted July 28, 2006 Okay. I remember trying with both CDRWin and mkisofs to make an ISO with file over 2GB and failing. Most likely limitations of the software (all my stuff has the 2GB limit also because of VB6 limitation). Anyone know a free (preferably open source) ISO builder with > 2GB support?
LIGHTNING UK! Posted July 28, 2006 Posted July 28, 2006 Ignoring the 'open source' bit, yeah ImgBurn!
cornholio7 Posted July 29, 2006 Posted July 29, 2006 oh yes it does - your version may not but it does build iso's. you can find out for yourself on the 1st.
Darkfalz Posted July 29, 2006 Posted July 29, 2006 Woohoo.............. I was going to add "yet" but didn't want to be presumptuous.
lfcrule1972 Posted July 31, 2006 Posted July 31, 2006 Being presumptious isn't the worst thing to be.......
