How can I erase data on a DVD+R disc?

Unfortunately once it is written it can not be erased, but if you are concerned about someone taking the data, you could drag it across the road, this will make the data un-readable.

in the adventure that your computer has a venture examining the documents there's a powerful danger it is so corrupt that no one will examine it, yet because it is not a DVD+RW you will not have the skill to delete something on it... it is readable not re-writable. examine the make/kind of your truthfully hardware (the DVD force) and on the manufactureres website they furnish you with a itemizing of reported extra properly suited discs to apply as not all are finished properly suited with all writers. my very own DVD writers fails every time i attempt to apply ipaq discs for documents backup... yet tesco's maximum inexpensive ones i ought to locate paintings great.

Open start menu. Click computer. Find the disk the drive is in. The right click the disk. Then formatt to FAT32

You can't. You can only erase from RW discs.

dvd+r media, once written onto, can not be erased.

nope, once you write to the disk it is there forever
