Hacking Windows XP and DVD-R. Bad combo?

[Aijelsop]

So I am trying to add folders to my DVD-R (note this is my only one left) and I get files on it using ImgBurn. Now I can't format OR delete those files...? I am trying to add an ISO to it (not a Wii ISO) and it won't let me do anything. It's telling my Disc Not Empty.

I figured this would be an appropriate place to put this considering back-ups use DVD-R...

How do I format it?

DVD-R is only writable ONCE. I think you're looking for DVD-RW.

 

[Aijelsop]

Dang... Well, thanks.

Any reason why it is writable only once?

Also, are DVD-RW compatible with Wii? I've heard DVD+R is bad, so are DVD-RW good to use like DVD-R?

 

[Strider]

Yes, the reason is the Media is physically altered. CD-R and DVD-R really have material BURNED inside.

... if you ... ah..never mind... GET TO KNOW YOUR BASICS.

 

[Aijelsop]

Really ...Are DVD-RW or DVD+RW compatible with Wii?

-RW : Only with some modchips.
+RW : Maybe without modchips if you can force the booktype to -R

I don't know if we can force DVD-RW booktype.

The data burns in there?
That must be why they call it burning, all makes sense now.

yes, it's literally melting the plastic with heat (250 degrees Celsius).

RW are not using the same physical structure (not a hole/plain system), but a reflective modification of a crystallization layer (25% 15% reflectivity).

OMG how can the computer produce 250 Degrees Celcius

So if the data is burnt in there, how is it read?

what you need to understand is that all the data in informatic/fax/numeric TV, optic fiber, etc. are coded in 2 different state :
Electricity or no electricity = light or no_light = 1 or 0 = hole or plain, etc.


virgin DVD : -------------------- (000000000000)
burned DVD : ---____-_-_-___

Data a series of dips on the surface of the CD/DVD. Its read by a laser which can tell when there is a dip in the surface and when there isn't, this makes binary code which it reads as files. Burning is done using the same laser with the power turned up so it can actually melt the plastic a bit and create the dips.

CDs are like records made at the smallest scale possible to fit as much data in as possible.

Thanks, it's nice to understand these things.
