Filling up a DVD-R

[racketboy]

I'm trying to backup some of my data on to some DVD-Rs.

I'm using Nero 6.

A DVD-R should hold 4.7GBs, right?

Well Nero tells me that I can only burn about 4.5GBs on the disc.

What gives?

 

[Curtis]

4.7 is probably some kind of pre-formatted or TOC exclusive value. Like a 80gig HD holds 76.4 (or whatever).

 

[racketboy]

Well CDRs can hold 700MBs like advertised

 

[Arakon]

dvd-r media hold 4.3 GB. as mentioned above, it's the same thing as with HDs.

 

[racketboy]

Well it looked more like 4.4 or 4.5 on Nero.

Why are CDs different?

 

[Pearl Jammzz]

I would like to know as well....I thought they were just like cds...

 

[Scared0o0Rabbit]

you may be able to go higher with it finalized or something. I haven't done much burning with my dvd burner yet.

The reason you get different sizes is because CDR's use the 1MB = 1024KB = 1024 x 1024 Bytes way of measuring space. DVD-R's and HD use the 1MB = 1000KB = 1000 x 1000 Bytes. It's sort of unofficial move to properly realign the whole damn byte sizing thing.

4.7 x 1,000,000,000 = 4,700,000,000

4,700,000,000 / 1073741824 (1024 x 1024 x 1024) = 4.3772161006927490234375 or about 4.38

See. Nero just uses the older 1024 method of figuring out KB, MB and GB.

 

[Gallstaff]

Yeah I always hated how it didnt round off to a nice number like how a meg was 1,024 kilos instead of 1000 and the like

 

[racketboy]

well that stinks considering it's a few 100MBs less than I was expecting to fix on it.

 

[Gallstaff]

And what might that be prytell?

 

[racketboy]

that I'm fitting on a disc?

well I'm in the process of backing up a lot of my data and moving stuff from CDs to DVDs.

This includes:

My Sega disc images

TV Divx Episodes

MP3s

Lossless compressed CDs.

Hi-res scans of personal photos

 

[Curtis]

How personal, racketboy? Just how personal are we talking?

 

[Gallstaff]
