How much capacity does a disc actually have?

[doctorjellybean]

I have an ISO which I need to burn, and windows reports its size as 766MB. If I put a 800MB CD-R in the burner and try to burn with ImgBurn, ImgBurn displays the following:

 

 

Disc Information:

Status: Empty

Erasable: No

Free Sectors: 359,847

Free Space: 736,966,656 bytes

Free Time: 79:59:72 (MM:SS:FF)

Supported Write Speeds: 16x, 24x

Try overburning it - CDs can usually overburn.

Those 90/100 minute cds still report all the disc info as if they were a standard 80 minute one.

 

So just 'continue anyway'.
