What is the actual size of a dvd??

[thilina]

I use nero to burn DVD's.I have noticed that even the size on the dvd is mentioned as 4.7GB,I can actually write only abt 4.2GB's.Why is this happening??

[gursimran_2006]

ssame as mine problem

[Pathik]

i can write 4.3 normally

perhaps the formatted and unformatted capacities. cuz 4.3 is the standard for DVD-R (single layer)

[sourav]

in manufacturing standards of hardisk 1 GB = 1000 MB.
So, when multiplied 4.3 GB * 1024 * 1024 * 1024 = 4617089843.2 bytes or 4.7*10^9 bytes (approx).

OK now divide (4.7 *10^9)/1024*1024*1024 = 4.3..

So you get 4.3 GB on the DVD or 4.7 GB of data as said my manufactures.

NB:- This may not be fully correct, i am sorry if i'm wrong. But I felt this correct as it works in HDD.

Actual Capacity of a single layered DVD blank media:

Blank Disc Capacity : [2,298,496 Sectors = 4.71 GB (4.38 GiB)]

cheerz

[Pathik]

@saurav i follow the same logic

[hemant_mathur]

Agreed with Saurav

[sysfilez]

saurav is right. even i get 4.3gb out of 4.7

[Pragadheesh]

even i can write 4.35GB in a dvd..

[jz2linkinpark]

everyone can write 4.35gb in dvd

[royal]

guys, I asked this elsewhere but got no answer...

has anyone actually overburned a DVD-R 4.7 GB ???

If so, please state the steps ...

Kalpik, perhaps you have done it ?

[prashanthnbhat]

I have observed that if you overburn a dvd, especially with nero, there will be no problem in the writing but during lead out will not be written properly. I'e lost two dvds trying to overburn

Isn't 4.35 GB sufficient at Rs 25-30 a disc. Laalchi

[kuldeep bhardwaj]

but i m able 2 burn it 2 4.5-4.55 GB. many times
