Can't back up ISOs larger than 4 GB - Club CDFreaks

SciFer · 31-03-2004

Hi, I'm not a newbie but I've never tried doing this until now. I created 8 different movies with Ulead DVD Workshop 2.0, I saved them on my hard drive as *.ISO. I've noticed that when I try to back up the actual iso (to a dvd-rw) that is 4.0 gb or larger, that it doesn't backup correctly. All the others that are under 4.0gb have no problem (verified iso after burn). When using "My Computer" and click once on Dvd drive it's in, on the left side (WinXP), under details, it will state the actual size of the file that it should be. But when you look inside to click on it once and view its detail, it shows ALOT smaller. Extracting it from the dvd-rw to hard drive gives me errors. I tried burning this in CDFS & UDF 1.02 file systems.

I'm assuming this is file system limitation like FAT. Is there anyway to do this with splitting it up? Is there another file system that can handle this?
If I do have to split it up can it be done in the iso format so that I can burn from the iso image off the dvd-rw media?

Thanks in advance

you have to install an NTSF partition that support much bigger files ,i thought that there isn"t even any limit on the file size with NTSF parition.

Let me clear it up a bit. I want to store it on a DVD-RW media not my hard drive. The file system on the DVD-RW media has the issue. I don't believe you can format a DVD-RW with NTFS? Is there a UDF version that will support this correctly (that is 1 file that is 4gb or bigger)?

Actually there is dvd image format that splits files under 2 gigs. Format is global-image. At least Stomp Record Now Max can handle these images.

I don't know if you can mount these images with Daemon Tool or similar if that is the case.
