? about DVD-R size

[mossmadness]

Why is it that if my Ritek DVD-R says it has a capacity of 4.7 GB, i can only burn 4.38 GBs. I'm trying to burn 4.6 GBs onto it using CopytoDVD. Is there a software that will let me burn 4.6 GBs worth onto the DVD.

4.7GB is 4.38 computer GB(1 kbyte=1024bytes).

So 4.6 computer gigabytes wont fit on a dvdr/w.

People who manufacture media and drives have special dispensation to call one billion bytes a gigabyte.

So they mean that the disc has 4,700,000,000 bytes on it.

To find out how many gigabytes that is in "computer gigs", you divide by 1024^3.

So 4,700,000,000 / 1024 = 4,589,842.75 Kilobytes

4,589,842.75 / 1024 = 4482.25 Megabytes

4482.25 / 1024 = 4.377 Gigabytes

See how this works? Same reason your 120GB hard disk only formats to about 112 gigs.

Blank DVD-R 4,489MB 4,706,074,624 bytes or 4.383GB
Blank DVD+R 4,483MB 4,700,372,992 bytes or 4.377GB

Nice.

Now the DVD-R vs DVD+R can really be an argument of "mine's bigger than yours".

LOL....try updating your site on DVD-Ram and maybe you can join the party.

Actually you really have to. Great site but the info is not accurate.

Tough to quote your site. Great effort but.....it seems like one big picture.

"As a person who has never owned or used a DVD-Ram drive. I will make this brief....

"Ram discs were written in cartridges at one point, though I believe many of them still exist as stand alone media these days. You must break the cartridge to remove the old discs."

Dude...wrong. Yeah maybe years ago. But relevant?

I applaud you for all of your hard work.

Not too sure I'm even tracking on the ATI stuff actually.

My information on DVD-RAM is what I've been able to verify from fairly reliable sources. If it's wrong, rewrite what you think it should be (then e-mail or PM it to me), and I'll look into it as time allows.
