First of all....
HAPPY NEW YEAR to everyone.

I'm hoping someone can help me on something I have been working hours to get
a solution, with no results.
I'm trying to download some songs ... to DVD-RW (and to DVD-R).
On the DVD problem I'm having, it shows that the disk has 4488.06 MB ... and
it should show as near as 4.7 GB !!!!! It shows this on ANY DVD I have tried.
On CD-RW and CD-R, it is shown that the disk space is 702 MB.
I have tried using NERO, Roxio Easy Creator, and CDBurnerXP Pro 3.
How come the disk space for the DVD's is lost down to 4488 MB ???

Thanks for any assistance or suggestions.

Disk drive capacities are measure in 'decimal' megabytes/gigabytes
where a megabyte is 1,000,000 bytes.

So 4.7GB = 4,700,000 'decimal' bytes

To convert it to what the computer understands you divide by 1024 to
convert to 'binary' megabytes/gigabytes so:

4,700,000 / 1024 = 4589.84375 bytes.

There's also a bit of a loss for the system giving the figure you are
seeing.

It's confusing, I don't know how it started but I suspect the marketing
people played their part 🙂

4488 MB = 4.6 GB
And there's the overhead.

Programmers work in powers of 2.

2^10 = 1024 (and the SI unit is Ki not K)
2^20 = 1024 x 1024 (1 048 576 and the SI unit was Mi not M)
2^30 = 1024 x 1024 x 1024 (1 073 741 824 and the SI unit is Gi not G)

Windows and Dos were written before Ki, Mi, and Gi were invented so used K, M, and G.

Also a sector is 512 bytes formatted but is 576 bytes unformatted. That is the drive itself uses 64 bytes for every 512 the operating system can use. These are timing bytes so the heads know when to start reading.

Take your standard 2 meg floppy. First of all 64 th / 512th (ie 1/8th) is being used by the drive electronics. More is used by the structures that allow an OS to find stuff on a disk. The end result is a 1.44 Mb floppy in the PC world. For the older 3 1/3 in disks a PC would format to 720K while a mac could save 800K due to the difference is OS overhead.

If I've understood correctly then it is correct to refer to a hard disk
as 1 GB but for memory it should be 1 GiB?

I've never seen those SI units in use though.

Only hard disk manufacturers use decimal. Everyone else uses binary. Everything about disks is reported in binary except from manufacturers. All the K, M, and G in Windows are really Ki, Mi, and Gi. But for compatability they still use decimal symbols.
