  Item 5.03.     Amendments to Articles of Incorporation or Bylaws: Change in
                 Fiscal Year.
  
       (a) Not applicable.
  
       (b)  PerfectData  Corporation,  a  Delaware  corporation  (the  "Company"),
  pursuant to a board  resolution  adopted on March 29,  2005,  changed its fiscal
  year end from March 31 to June 30.  Because  the  Company  has  already  filed a
  Quarterly  Report on Form  10-QSB  for three  months  ended  June 30,  2004,  no
  transition report will be required for the period April 1, 2004 through June 30,
  2004.  The  Company  will file a  Quarterly  Report on Form 10-QSB for the three
  months ended March 31, 2005,  and an Annual Report on Form 10-KSB for the fiscal
  year ended June 30, 2005.
  
       The foregoing action assumes that the previously reported  transaction with
  Sona Mobile,  Inc. ("Sona") is not consummated prior to June 30, 2005 or at all.
  As  previously  reported,  the Agreement and Plan of Merger dated as of March 7,
  2005 by and among the Company,  its  wholly-subsidiary  ("Merger  Sub") and Sona
  provided  that, if the Merger of Sona with and into Merger Sub ("the Merger") is
  consummated, then at the Effective Time (i.e., when the Merger becomes effective
  through the filing of a  certificate  of merger in the State of  Delaware),  the
  Company  will change its fiscal year to December 31 to match that of Sona.  This
  change will be reflected in the  Company's  Current  Report on Form 8-K in which
  the audited  financial  statements of Sona are filed.  In such event there is no
  transitional  period to be reported.  In a Schedule  14F-1 being  simultaneously
  filed,  the Company  reported that it and Sona curently expect to consummate the
  Merger  transaction  on April  15,  2005,  although  fulfillment  of  conditions
  precedent could delay the closing.

       Pursuant to the  requirements  of the Securities  Exchange Act of 1934, the
  registrant  has duly  caused  this  Report  to be  signed  on its  behalf by the
