Rapid development of computer is followed by development of digital storage device. One common problem of digital storage device is data loss. The problem of data loss could be solved by using file carving techniques, for example. File carving techniques could be performed using carving tools, such as PhotoRec and Foremost. This research was conducted to know and to compare performance of carving process from PhotoRec and Foremost based on three parameters, which are the number of return files, file validation, and the rate of process. The research used simulation methods. The process of file validation uses hash algorithm SHA1 to make sure the similarity between original and return files. The result of this research shown with table that PhotoRec has a higher performance than Foremost. PhotoRec have return files less than Foremost, but PhotoRec has a higher percentage of valid files than Foremost. Additionally, the rate of carving file process done by PhotoRec is higher than Foremost. Finally, the research reaches the conclusion that PhotoRec is better than Foremost.
