Emsa Disk Check: CD/DVD/HDD Disk Diagnostics Utility (859 words)
Emsa Disk Check is a dual-purpose utility, for disk checking (prescan and full disk reading) and also benchmarking.
What it does, is scanning/reading the entire contents of a disk (CD, DVD or hard drive; or even floppy) and show any read errors that may appear, but also show drive speed information, progress statistics etc. It was designed with simplicity in mind, but usefulness for the user.
Tip: You may want to try reinserting a disk and performing more than one check, for more accurate results of benchmarking, as different reads of same disk may be performed at different speeds by the same drive.
