Re:   Verdisys, Inc. (formerly Reconstruction Data Group, Inc.)


Ladies and Gentlemen:

We were  previously  the principal  accountants  for Verdisys,  Inc.  (formerly,
Reconstruction Data Group, Inc.), and we reported on the financial statements of
Reconstruction  Data Group,  Inc. as of December 31, 2002 and 2001,  and for the
years ended December 31, 2002 and 2001. On September 25, 2003,  our  appointment
as  principal  accountants  was  terminated.   We  have  read  Verdisys,  Inc.'s
statements  included under Item 4 of its Form 8-K, dated September 26, 2003, and
we agree with such statements.


Yours truly,


/s/ Cordovano and Harvey, P.C.
