But if your computer came from an OEM manufacturer (Dell/HP etc) for example, you might have no information about what the drive can do apart from the fact you have a DVD Writer. If you know the full capabilities of your drive, it’s not a problem. It’s quite common for people to buy a spindle of blank discs without even thinking that they might not actually work in the drive because it doesn’t support that type of media. As you’ll probably know, writable optical media can come in two different types, -R and +R, and you can have drives that might read all minus types but not all plus types, or a drive might be able to read a dual layer plus disc but cannot write to it etc. Even though fast USB drives and online downloads have reduced the need for reading and writing from optical drives, they can still be highly valuable computer components.Īlthough not such an issue on newer machines because their DVD-RW drives can usually read most types of media, slightly older or cheaper drives sometimes have a few reading or writing capabilities missing such as the ability to write to a dual layer DVD disc or certain re-writable discs. If you’re really lucky you might have a drive capable of reading Blu-ray discs, and high end machines possibly have drives that can write BD-R media as well. Most desktop and laptop computers these days are equipped with some sort of optical drive, usually a DVD drive because they are no more expensive than CD only drives which have all but disappeared.
