I downloaded WinMFS and unzipped, and turned off PC. Removed HD from TiVo and installed in PC. Restarted PC, launched WinMFS. Clicked on file, select drive. But there are no drives shown in wither the A drive or B drive sections. I tried several times shutting the PC off, and disconnecting/reconnecting the SATA and power cables. Even tried all the available SATA connections on motherboard (Dell Dimension 9100). Any suggestions?
