My dvd recordable(RW)has it total space 0b.i bought it from a specialty shpo so whats the problem with it???

Answer 1

the re-writable disks require an initialization or formatting before recording can begin. this is different from the regular record once disks which can start recording off a blank disk.

Answer 2

When you put it in your dvd burner it should automatically format the disk. Maybe it has no space because it has alreay had all the space used up. Try erasing it.
