This Windows program doesn’t need to be installed, so you can run it from any type of media. Copying it to a USB flash drive, for example, lets you carry it around to check several computer setups. An interesting feature of Emsa DiskCheck is the ability to see other statistics about the ​CD or DVD you’re working on. The statistics section, for example, shows you how many files are on the disc and how much space they take up. You can also measure your drive’s ability to read the disc by looking at the speed statistics. CDCheck can also be used for comparing folders and files, which is a useful feature if you want to compare the files written to disc with the source files usually stored on your hard drive. CDCheck can also double as a file recovery tool to recover files from a disk that Windows can’t read. Overall, a great utility to install to keep a check on all your media. This one is a fantastic option for helping you pinpoint exactly where a problem may occur. Brasero is the default GNOME DVD burner, but it also can check your discs to make sure that they’re working correctly. The interface is straightforward, and you can perform a scan in seconds.
