Even these utilities aren't foolproof, because some high-quality disc manufacturers have sold master stamping dies to other companies, whose discs are identified as coming from the company that produced the stamping die rather than the company that actually produced the discs.
The best way to determine disc types is to use DVD Identifier ( ) or CD-R Identifier (no web site search Google). In general, the best discs are made in Japan or Singapore and the worst in Taiwan and Hong Kong. It's also common for spindles of different capacity 25, 50, or 100 all with the same brand name, to contain discs made by different companies. It's quite possible to buy two apparently identical spindles of discs, sometimes with the same SKU, and find that one was made in Japan and the other in Taiwan, by different companies. Some companies put their own brands on discs from different manufacturers. Some companies manufacture discs that are rebranded by several other companies, and may or may not also be sold under the manufacturer's brand name. There is little relationship between the brand name of a disc and the company that made it. Assuming the drive is installed and configured properly initially, it should be problem-free throughout its service life. Optical drives generally work or they don't.
