Exhibit (a)(7)


                              QUANTUM CORPORATION
                    VOLUNTARY STOCK OPTION EXCHANGE PROGRAM
                         PROMISE TO GRANT STOCK OPTION

     In exchange for your agreement to cancel a stock option covering _______
shares of Quantum's common stock ("Old Option") granted by Quantum Corporation
("Quantum"), Quantum hereby promises to grant you a stock option covering
_________ shares of Quantum's common stock on January 7, 2002 (the "New
Option"), which is the same number of unexercised shares subject to the Old
Option which you tendered for exchange and which was cancelled on July 5, 2001.
The exercise price of the New Option will be the closing price of Quantum's
common stock as listed on the New York Stock Exchange on January 4, 2002.

     The New Option will have the same vesting schedule as the corresponding Old
Option you tendered for exchange.  However, the vesting of the New Option will
start over on the date of grant of the New Option.  For example, and except as
described below, if you elected to cancel an Old Option that was scheduled to
vest monthly over four years, your New Option will be scheduled to vest monthly
over four years from the date the New Option is granted. Because the vesting
schedule for the New Option will not begin until the grant date of the New
Option, you will lose the benefit of all vested shares under the Old Option that
was cancelled.  Upon the grant of the New Option, you will receive credit
towards the New Option's vesting schedule for the approximately six-month period
between July 5, 2001 and January 7, 2002. This will have the effect of
shortening the date the New Option is scheduled to fully vest by approximately
six months.

     For performance-accelerated options (PASOPs) only, the New Option will have
the same vesting schedule as the corresponding Old Option you tendered for
exchange.  Upon the grant of the new PASOP, you will receive credit for vesting
accrued prior to the cancellation of the old PASOP and you will receive credit
for the approximately six-month period between July 5, 2001 and January 7, 2002.
Therefore, for PASOPs only, you will not lose the benefit of shares that have
vested under the Old Option that was cancelled.

     The New Option will otherwise be subject to the standard terms and
conditions under Quantum's Supplemental Stock Option Plan (the "Plan"), a new
option agreement between Quantum and you, and if you are an employee or resident
in the U.K., a joint election whereby you agree to accept the transfer of the
whole of the National Insurance liability related to the New Option.

     In order to receive the New Option, you must be an eligible employee of
Quantum or one of our subsidiaries as of January 7, 2002.  This promise to grant
does not constitute a guarantee of employment with Quantum or any of our
subsidiaries for any period.  Your employment with Quantum or any of our
subsidiaries remains "at-will" and can be terminated by either you or Quantum at
any time, with or without cause or notice, subject to the provisions of local
law.  If you voluntarily terminate your employment with Quantum or any of our
subsidiaries or if your employment is terminated by Quantum or any of our
subsidiaries for any reason whatsoever before January 7, 2002, you will lose all
rights you have to receive the New Option.

     This Promise is subject to the terms and conditions of the Offer to
Exchange dated June 4, 2001, the memorandum from Michael Brown dated June 4,
2001, and the Election Form previously completed and submitted by you to
Quantum, all of which are incorporated herein by reference.  These documents
reflect the entire agreement between you and Quantum with respect to this
transaction.  This Promise may only be amended by means of a writing signed by
you and a duly authorized officer of Quantum.
