    In the era of digital media where users create multimedia, and the size and number of media files increase, the importance of robustness of storage devices is also increasing. Even a fault in storage may lead to not only damage of a file but also cause fatal errors that affect the system. To prevent the storage systems from such errors, it needs to be tested for physical errors and analyze their failure behaviors to take appropriate actions to prevent them. SOAR is an independent fault injection system with an SATA multiplexer to inject faults to not only storages used by desktop applications but also CE devices. SOAR runs real-time on top of Linux. SOAR injects both physical and logical errors on storage devices or device driver layer depending on the type of errors user wants to generate, respectively. Along with SOAR, we designed three test frameworks for multimedia players, file system benchmark tools, and file system. As the case study of the usage of proposed fault injection system, we tested and verified five multimedia players with a CE device, two file system benchmark tools, and four file systems 

Keywords: fault injection, physical fault, logical fault, fault tolerance, fault robustness
