EXPLANATORY NOTE: This Amendment No. 1 on Form 10-K/A to the MTI
Technology Corporation (the Company) Annual Report on Form 10-K for the year
ended April 5, 2003 (the Original Filing) is being filed to correct footnote
6 to the Summary Compensation table included in Item 11 of the Original
Filing (incorporated by reference to portions of the Companys definitive Proxy
Statement filed in connection with the solicitation of proxies for the
Companys Annual Meeting of Stockholders to be held August 21, 2003).

Footnote 6 to the Summary Compensation table incorrectly stated that
Keith Clark, the Companys Executive Vice President, Worldwide Operations, was
paid in Euro, when it should have stated that Mr. Clark was paid in British
pounds sterling. While the Company does not believe this error to be material,
the Company is amending footnote 6 of the Summary Compensation table to
correct the error. The entire Summary Compensation table is included herein
for convenience, but no changes to the table are made other than the above
described amendment to footnote 6. No further revisions have been made to the
Original Filing, and unaffected items (including portions of Item 11 other than
the Summary Compensation table) have not been repeated in this filing.




ITEM 11.

COMPENSATION OF DIRECTORS AND EXECUTIVE OFFICERS AND OTHER INFORMATION

The following table sets forth for each of the Companys last three
completed fiscal years the compensation of Thomas P. Raimondi, Jr., the
Companys Chairman, President and Chief Executive Officer, and the four most
highly compensated executive officers as of the fiscal year ended April 5,
2003, other than Mr. Raimondi whose total annual salary and bonus for the last
fiscal year exceeded $100,000 (collectively, the Named Executive Officers).
