Last time I called, the Recovery tool was NOT a tool provided/made by Buffalo... They will require you to Mail in your LS-X unit to have it reset.
this thread is also in the SOLVED forum, IE no-one really looks here..
If you really want the tool, just Google lsrecovery (should also work for forum searching), then again, they are adamant about removing the links because 1, its not a buffalo provided tool, and 2, its a huge security risk for company's, and 3, there have been posts where people claim it wiped their entire unit...
Russian roulette at your own risk!
