Why only 4.4G on a 4.7G disc...?

[808smokey]

If this is a dumb question it's cause I'm tired. Or if it's in the wrong forum I apologize I just thought of this...

Why can I only burn 4.4G on a 4.7G DVD+R?

I use Maxell Brand Discs (the ones at wallmart, multi color discs) the software I use is DVD Decrypter, DVD Shrink and Copy to DVD Sometime DVD Xcopy Xpress. I have an NEC-1300A burner. I read some where in these forums earlier today about overburning, I can't even full burn Is it my burner or the software I'm using? Just wondering.

Thanks

It's 3.38 (and change)actually.
Marketing bullshit. Bigger numbers always confuse and awe the ignorant. (I guess the reverse would apply if your were making small things)

In the computer world of ZERO and ONE , 1024 is (a thousand) equated to 1000 . Example a 1.44Mb floppy is really 1.38 ish Mb of volume.

Maybe Princos.
My discs can hold 4.38

OH ..... and while we are here.....

* 17 " monitors ARE NOT 17" (measured corner to corner) but typically ~16" viewable.
* 80Gb hard drives...... aren't 80Gb
* 480 M BIT/sec is NOT fast as it is only 480/8= 60Mb/sec
* AND ..... maybe it is my imagination.......but the volume in beer bottles has decreased.



We have a winner here : 128Mb ram = 1024*128 --> 131072 (computer Mb)

DOH - TYPO
Correct 4.38 ...... 4 missing on the keyboard

"AN IMPORTANT NOTE ON UNITS – GB versus Billion Bytes

A single layer recordable DVD typically holds 4.7 billion bytes (G bytes), not 4.7 gigabytes (GB). It only holds 4.38 gigabytes (GB). A double-sided, dual-layer DVD holds 17 billion bytes, which is only 15.90 GB.

The confusion arises because the SI prefixes kilo, mega and giga normally represent multiples of 1000. However, when used in the computer world to measure bytes these same prefixes generally represent multiples of 1024 (in the binary world, 2^10 =1024). This means that a kilobyte = 1024 bytes, a megabyte = 1,048,576 bytes, and a gigabyte = 1,073,741,824 bytes. So 4,700,000,000 bytes = 4.38 gigabytes.

Unfortunately, most DVD figures are based on multiples of 1000, which means that your computer operating system and your DVD are using the same prefix to mean different things. This is an extremely important distinction to keep in mind when preparing the files for your DVD.

To make things worse, data transfer rates when measured in bits per second are almost always multiples of 1000, but when measured in bytes per second are sometimes multiples of 1024. For example, a 1x DVD drive transfers data at 11.08 million bits per second (Mbps), which is 1.385 million bytes per second, but only 1.321 MegaBytes per second. The 150 KB/s 1x data rate commonly listed for CD-ROM drives is "true" kilobytes per second (multiple of 1000), since the data rate is actually 153.6 thousand bytes per second. "

True. 5.7MB less (about 5 seconds movie)

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
(mrbass.org)

However I've never had a problem copying a DVD-R to DVD+R.
They daren't write a very full DVD-R disc!

Interestingly, I seem to recall reading quite a few years ago (when hard disks first became big enough that people noticed a substantial loss to this accounting discrepancy) that the manufacturers of storage media had managed to get permission from the government to market using MB = Million Bytes, GB = Billion Bytes. Otherwise they'd be liable to be sued for false advertising.

Don't feel bad for asking the question....EVEN software companies screw it up.

IC7 reports the wrong file size in the program. However if you add up the files sizes by hand and then divide the result by 1024 you will get the correct size of the file after processing. Now I'm not sure if their file size is measured in bytes and that's why it's wrong or what, I've not investigated it that far.

Nope. I drank a lot of beer last night and this morning *everything's* loud!

trhouse, thanks for your excellent explanation. i knew it was related to terminology, but the details were a bit murky.

[Metaluna]

In case anyone's interested, there are actually international standards to distinguish between power of 10 abbreviations (giga, mega, etc.) and power of 2 abbrevations. If you mean powers of two, there are new abbreviations like gibibyte (GiB), mebibyte (MiB), etc. It's all explained here:

Hardly anyone seems to use them though (they do sound kind of funny).

[Gurm]

They're coming into style. Bit Torrent uses MiB and KiB.

Anything to do with 7 inches equaling almost 18 centimeters ?

OOPS- wrong forum.

Dear Penthouse,
I never thought this would happen to me..........


Larger DOES "sound" more impressive !!!

[jdizzy40]

Whats a picture of my wife doing under your name?

[jtommyj]

I get a lot of compliments on the old ladies pic. That's one of those glamorshhot deals. She's 31 ,I'm 42. Get it while you can, I guess !!

[Coaster Queen]

you guys are all hard drive and RAM. Its all about keeping your firmware updated.

Me, me, me, my firmwares, OS, Nero, RecordNow, DVD Decrypter, DVD Shrink, DVD2one,..... and OTHERS are UP to date!

[jtommyj]

Someone told me that there is a little blue pill you can put in your DVD burner to keep it's firmware up . Any truth to that ?
Said they saw Bob Dole on a commercial or something.

No. That blue pill leads down a whole different path. Take it at your own risk. You have been warned.

Thanks for clearing that up.

:c) No problem.

Thats true too because when I bought my 2x160GB Maxtors I thought I got ripped at first when I went into Windows and saw 152 GB.
