CUSIP No. 74758R109                SCHEDULE 13D

Item 1. Security and Issuer.

     Except as expressly restated and amended below, the Schedule 13D as filed
on behalf of BKF Capital Group, Inc. and Steven N. Bronson with respect to the
shares of common stock, no par value per share (the "Common Stock") of Qualstar
Corporation, a California corporation, with its principal offices located at
3990-B Heritage Oak Court Simi Valley, CA 93063 (the "Issuer") remains in full
force and effect. The Issuer recently reported that as of February 10, 2012, the
Issuer had 12,253,117 shares of Common Stock outstanding.

Item 2. Identity and Background.

     (a) This Schedule 13D Amendment No. 3 is filed on behalf of BKF Capital
Group, Inc. ("BKF Capital") and Steven N. Bronson.

     (b) BKF Capital and Mr. Bronson's business address is 225 N.E. Mizner
Boulevard, Suite 400, Boca Raton, Florida 33432.

     (c) BKF Capital is a publicly traded corporation and Mr. Bronson is the
Chairman and President of BKF Capital. Mr. Bronson is the sole owner of BA Value
Investors, LLC, a Florida limited liability company.  Mr. Bronson is also
President of Catalyst Financial LLC ("Catalyst"), a broker-dealer registered
under the Act.  Catalyst's offices are located at 225 N.E. Mizner Boulevard,
Suite 400, Boca Raton, Florida 33432.

     (d) During the last five years neither BKF Capital nor Mr. Bronson have
been convicted in a criminal proceeding (excluding traffic violations or similar
misdemeanors).

     (e) Neither BKF Capital nor Mr. Bronson have, during the last five years,
been a party to a civil proceeding of a judicial or administrative body of
competent jurisdiction and as a result of such proceeding was or is subject to a
judgment, decree or final order enjoining further violations of, or prohibiting
or mandating activities subject to the federal or state securities laws or
finding any violation with respect to such laws.

     (f) BKF Capital is organized under the laws of the State of Delaware and
Mr. Bronson is a citizen of the United States of America.

Item 3. Source and Amount of Funds or Other Consideration.

    Not applicable.

Item 4. Purpose of Transaction.

    On February 15, 2012, BKF Capital sent a letter (the "Feb. 15th Letter") to
the Board of Directors (the "Board") of Qualstar Corporation ("Qualstar"). In
the Feb. 15th Letter, BKF Capital advised the Board that Qualstar's business was
underperforming and its shares of common stock were trading below net tangible
book value. Moreover, BKF Capital requested the Board to take action to maximize
shareholder value. Specifically, BKF Capital asked the Board to consider the
following courses of action: (1) to divest Qualstar's unprofitable Tape
Libraries business; (2) to distribute Qualstar's excess cash from the sale of
marketable securities held by Qualstar to its shareholders; and (3) to focus
Qualstar's resources on the generally profitable Power Supply business. In a two
sentence letter, dated February 24, 2012, the Board responded to the Feb. 15th
Letter stating that it would consider the issues raised in the Feb. 15th Letter,
but the Board failed to address any of the matters asserted in the Feb. 15th
Letter.

     Based on the Board's inaction, BKF Capital has determined to withhold its
votes for Qualstar's proposed slate of directors at Qualstar's 2012 Annual
Meeting scheduled for March 21, 2012. On February 28, 2012, BKF Capital issued a
press release containing an open letter to the Shareholders of Qualstar
informing them of BKF Capital's intention to withhold its votes and to urge all
of Qualstar's shareholders to also withhold their votes for directors proposed
by Qualstar at Qualstar's 2012 Annual Meeting scheduled for March 21, 2012.
Attached hereto as an exhibit to this Schedule 13D is a copy of BKF Capital's
open letter to the Shareholders of Qualstar.




      BKF Capital acquired and holds the shares of Common Stock for investment
purposes. BKF Capital may: (i) increase or decrease its beneficial ownership of
Common Stock or other securities of the Issuer, (ii) sell all or part of its
shares of Common Stock in open market or privately negotiated sales or
otherwise, or (iii) make further purchases of shares of Common Stock or other
securities of the Issuer through open market or privately negotiated
transactions or otherwise. BKF Capital has not reached any decision with respect
to any such possible actions. If BKF Capital does reach a decision to undertake
any of the above described possible actions, it will, among other things, timely
file an appropriate amendment to this Schedule 13D.

Item 5. Interest in Securities of the Issuer.

     (a)(b) BKF Capital owns an aggregate of 1,855,591 shares of the Issuer's
Common Stock, representing approximately 15.1% of the total shares of Common
Stock deemed outstanding. Steven N. Bronson as the Chairman and President of BKF
Capital may be deemed to be the beneficial owner of the shares of Common Stock
held by BKF Capital. Mr. Bronson, as the sole owner of BA Value Investors, LLC,
beneficially owns an additional 57,700 shares of Common Stock, as to which he
possesses voting and disposition power. Accordingly, Mr. Bronson may be deemed
to beneficially own an aggregate of 1,913,291 shares of the Issuer's Common
Stock, representing approximately 15.6% of the total shares of Common Stock
deemed outstanding.

     (c) Not applicable.

     (d) Not applicable.

     (e) Not applicable.

Item 6. Contracts, Arrangements, Understandings or Relationships with Respect
        to Securities of the Issuer.

         None

Item 7. Material to be Filed as Exhibits.

         None


        After reasonable inquiry and to the best of my knowledge and belief, I
certify that the information set forth in this statement is true, complete and
correct.

February 28, 2012

Dear Fellow Qualstar Corporation Shareholders:

With its ownership of over 15% of the outstanding stock of Qualstar Corporation
("Qualstar" or the "Company"), BKF Capital Group, Inc. is the Company's second
largest shareholder. We intend to withhold our votes for the Company's directors
at the upcoming Annual Meeting of the Company's shareholders on March 21, 2012,
and we strongly urge you to do the same.

The Company's shareholders are being asked at the Annual Meeting to elect the
full board, consisting of William J. Gervais, Stanley W. Corker, Lawrence D.
Firestone, Carl W. Gromada, Robert A. Meyer and Robert E. Rich. With the
exception of Mr. Firestone, who was appointed to the Board last May, each of the
directors has been on the Board for at least the last six years. During that
period of time, and since 2003, the Company has not once been profitable.

Other than Mr. Gervais, none of the directors have a meaningful stake in
Qualstar. According to the Company's proxy statement for the Annual Meeting,
excluding Mr. Gervais, the directors collectively own only 1.3% of the Company's
outstanding stock (not taking account of stock options). Meanwhile, Mr. Gromada
sold 40,700 shares last year at prices ranging from $1.75 to $1.80 per share.
This price range represented a discount to Qualstar's cash and marketable
securities per share at the time of sale. To us, this is indicative of a Board
that, with the exception of Mr. Gervais, is financially disengaged from the
Company and lacks confidence in its prospects.

BKF believes that shareholders must send a firm message to the directors that,
in their view, the Board is not discharging its fiduciary responsibilities and
is not working towards maximizing shareholder value.

o    Qualstar's share price is depressed by many fundamental and relative
     performance measures.

o    There does not seem to be a sense of urgency by the Board to setting
     Qualstar on a course to profitability.

o    Over the past decade, the Board has made no attempt to redeploy Qualstar's
     assets in order to maximize value.

o    There does not appear to be any strategic direction on the part of the
     Board to respond to the changing financial and business realities affecting
     Qualstar's business.

The Company's legacy Tape Libraries segment is a case in point. On the Company's
earnings conference call of February 14, 2012, Mr. Gervais stated that the
market for the Tape Libraries products had decreased from a peak, presumably in
the early 2000s, of approximately $1.5 billion annually to its present level of
approximately $600 million. There were 35 industry competitors at the peak
versus 8 today, which seemingly indicates that other players have made the
economically rational decision to get out of this business. Qualstar's Board, in
contrast, has simply sat by with this money-losing business, offering no
indication whether the segment will ever result in positive earnings, in the
near-term or long-term, and just "throws good money after bad."




On February 15, 2012 we sent a letter to the Qualstar Board, which we attached
as an exhibit to our Schedule 13D filing on February 21, 2012. In the letter, we
suggested three steps that the Board can and should take to maximize shareholder
value.

1.       Divest the unprofitable Tape Libraries business.
2.       Distribute excess cash from the sale of marketable securities to the
         shareholders.
3.       Focus Qualstar's resources on the generally profitable Power Supply
         business.

We also asked the Board to present a strategic turnaround plan to Qualstar's
shareholders. While developing and implementing a plan to refocus operations may
take some time, the Company should immediately be returning to shareholders a
majority of Qualstar's excess cash from the sale of its marketable securities.
Thus far, the Board has responded to our letter with only a terse
acknowledgement of its receipt, saying it will "carefully consider" our
suggestions.

We are not seeking at this time to oust the Board or change control of the
Company; however, we do wish to send a strong message to the Board that
shareholders are no longer satisfied with the status quo. We insist on a
profitable, dynamic company that is run to generate earnings for the benefit of
the shareholders.

By withholding votes for the directors at the Annual Meeting, shareholders will
be voicing their dissatisfaction with the current operations of Qualstar and
will be making an unmistakable call for change.

We strongly urge all shareholders to vote "Withhold" in the election of
directors at the 2012 Annual Meeting of Qualstar Shareholders to be held on
March 21, 2012.

Sincerely,

/s/ Greg Heller

Greg Heller
