碩士 === 國立臺灣大學 === 電機工程學研究所 === 92 === Because of rapid development of inter-net and multi-media data bases, need for a big storage system becomes more and more important. The advanced storage system must provide rapid data processing ability and stable storage environment in order to avoid data losing. For the purpose mentioned above, many fault-tolerant methods are derived. We hope that information can be transmitted and stored correctly by some methods using software or hardware when there are disturbances, like heat noise, broken machine, noisy transmitting channel and so on. Error control coding is the most important method within all error concealing methods. Different error correcting codes are designed in different environments in order to avoid error losing. In the thesis, we will use Reed Solomon Code which is designed according to properties of advanced RAID system to handle two disk failures in RAID system. Therefore, the failed data in disks can be recovered and system still can work as usual without broken.
