This file contains a batch file and the devcon utility which you can use to uninstall and reinstall your eSATA card drivers with one command from the command line. Or, you make an icon to run it also. Occasionally for reasons the chip makers can not explain, on certain systems, eSATA drives will “pop” off-line. You can install these files in a directory of your choice and run the Rscan.bat file to uninstall and reinstall your eSATA drivers. THIS ONLY WORKS with Silicon Image chip based eSATA controller cards. Run from your command line. CAUTION! This script is not well tested and should only be used by technical or experienced users.
