Question about single layer DVD capacity

Two programs I have keep showing a single layer DVD as having 7.95GB capacity. Both SmartBurn and CDCheck show this, and only DVDInfoPro, is showing 4.38/4.71 GB. The SmartBurn even recognizes it as single layer. I’ve never used any of this software before so I am curious as to why it was showing that.

Only after I bought some blank DVDs off of eBay, did I hear about the fake ones. These are supposed to be Taiyo Yuden Silver Thermal Lacquer 8x DVD-Rs. The code on the bottom does read GG00…, but I was concerned about this.

Thanks for any help.

If it’s a single layer disc its capacity is 4.38gb.

Try this for explanation.

I think xrs77 knows this. But he’s wondering why two programs are erroneously showing the wrong capacity.

This has been posted about many times, try search for more threads, the correct size is 4.38 GiB/Gibibyte (a bit less for +R) the reason is some people use the wrong number base when working with computers its always base 2 or binary, not denary (base 10).

I remember when doing my degree one of the proffs would hit the roof if you said MB for MiB or GB for GiB and so on.

Thanks for all the responses.

Is this about the 4.38/4.71 that I posted? The problem I was having was with the first two software showing 7.95 GB as the capacity.
