DVD storage size?

Why does nero's disk space bar go yellow after 4500MB? My DVD says it can store 4.7GB, that's over 4700MB, so it's not filled yet.

Re: DVD storage size?

In binary 1 Kilobyte = 2^10 bytes = 1024 bytes.
In binary 1 Megabyte = 2^20 bytes = 1048576 bytes.
In binary 1 Gigabyte = 2^30 bytes = 1073741824 bytes.


In decimal 1 Kilobyte = 10^3 bytes = 1,000 bytes.
In decimal 1 Megabyte = 10^6 bytes = 1,000,000 bytes.
In decimal 1 Gigabyte = 10^9 bytes = 1,000,000,000 bytes.


4.7 Gigabytes = 4,700,000,000 bytes in decimal Or 4,700,000,000 / 1073741824 = about 4.3772 actual computer Gigabytes.

Three simple rules:

1. Never Change the Deal
2. No Names.
3. Never Open the Package.

Re: DVD storage size?

The megabytes and gigabytes are defined differently.

Windows (and probably Nero) defines 1 MiB = 1024 * 1024 Bytes and 1 GiB = 1024 MiB.

The definition on the DVD packaging is 1 GB = 1000 MB = 1000^3 Bytes.

A DVD has just over 4,700,000,000 Bytes available space, which is 4.7 GB or 4.38 GiB or 4482 MiB.

EDIT: platinumsword was quicker.

So why does Nero go yellow when the DVD isn't filled up yet?

4,700,000,000 / 1024^2 = 4482MB (ish)

Drat! too slow

Re: DVD storage size?

When I burn DVDs, is it safe to fill it near the limit?

Depends on the quality of the DVD media you use and on whether it has been damaged near the outer edge.

The part near the outer edge is the first to get damaged by handling, it's most likely to be problematic on cheap low quality DVD media, and if you burn at a high speed, the outer edge is also the part that is burned the fastest with highest risk of burning problems.

So it's a question with no clear answer.

Re: DVD storage size?

I would stop at the limit, remember that you burn from the middle to the outside of the medium, so the closer you get to the outside edge the more susceptible it is to damage.

Re: DVD storage size?

So what do you recommend filling the DVD up to?

I use Verbatim Taiwan DVDs.

Which limit? The 4482MB? Is that all the way to the outer edge?

So what do the yellow marker and red marker for Nero do?

Also, if I stop at anywhere before 4464 MB then I'm totally safe?

Edit: To rephrase my question, is it safe to go all the way up to the official limit of 4464 MB? Not the overburn limit.

Re: DVD storage size?

Whatever software that you decide on using, use the defaults and you will be safe. That why they are there.

If you decide to over burn the limits in a general sense be it a dvd or a cd and go to far there is a change that the player in question might have a difficult time reading the disk. Like what was said, it is not a straight clear answer.

Man, "the limit" is set by you used media and filesystem, here 4482mb!
If you need more, use a DoubleLayer/DualLayer.
