For mounting USB HDD MSPE and automountdrives works in the same way. In my tests i like MSPE cos it can also mount hidden partitions by default and we can control it's behavior using command line switches. On the other hand Automountdrives didn't offers any command line switches and it can't mount hidden partitions. New MSPE is way better with numerous bug fixes. Only problem remaining is WD passport issue but that may got fixed in the next version.
