Accounting Policies [Abstract]
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	NOTE 2: SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Basis of Presentation The accompanying interim unaudited condensed consolidated financial statements of the Company have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim financial information. All intercompany balances and transactions have been eliminated. Certain information and footnote disclosures normally included in annual financial statements have been condensed or omitted. The Company believes the disclosures made are adequate to prevent the information presented from being misleading. However, the accompanying unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto included within the Company’s most recent Annual Report on Form 10-K filed with SEC on August 6, 2019, which includes the audited and consolidated financial statements for the Company’s fiscal years ended March 31, 2019, March 31, 2018 and March 31, 2017. The accompanying unaudited condensed consolidated financial statements reflect all adjustments (consisting only of normal and recurring items) necessary to present fairly the Company’s financial position as of December 31, 2018 and the results of operations, cash flows, and changes in stockholder’s deficit for the nine months ended December 31, 2018 and 2017. Interim results are not necessarily indicative of full year performance because of the impact of seasonal and short-term variations. Use of Estimates The preparation of these condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions. Certain accounting estimates involve significant judgments, assumptions and estimates by management that have a material impact on the carrying value of certain assets and liabilities, disclosures of contingent assets and liabilities and the reported amounts of revenues and expenses during the reporting period, which management considers to be critical accounting estimates. The judgments, assumptions and estimates used by management are based on historical experience, management’s experience and other factors, which are believed to be reasonable under the circumstances. Because of the nature of the judgments and assumptions made by management, actual results could differ materially from these judgments and estimates, which could have a material impact on the carrying values of the Company’s assets and liabilities and the results of operations. Fair Value Measurements The fair value of financial instruments is based on estimates using quoted market prices, discounted cash flows or other valuation techniques. Those techniques are significantly affected by the assumptions used, including the discount rate and the estimated timing and amount of future cash flows. Therefore, the estimates of fair value may differ substantially from amounts that ultimately may be realized or paid at settlement or maturity of the financial instruments, and those differences may be material. Accordingly, the aggregate fair value amounts presented may not represent the value as reported by the institution holding the instrument. The Company uses the three-tier hierarchy established by U.S. GAAP, which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value to determine the fair value of its financial instruments. This hierarchy indicates to what extent the inputs used in the Company’s calculations are Level 1: Unadjusted quoted prices in active markets for identical assets or liabilities. Level 2: Other than quoted prices that are observable in the market for the asset or liability, either directly or indirectly, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or model-derived valuations or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. Level 3: Inputs are unobservable and reflect management’s estimates of assumptions that market participants would use in pricing the asset or liability. New Accounting Pronouncements Adopted in Fiscal 2019 In May 2014 the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606 No. 2015-14, Deferral of the Effective Date No. 2016-08, Principal versus Agent Considerations (Reporting Revenue Gross versus Net) No. 2016-10, Identifying Performance Obligations and Licensing No. 2016-02, Narrow-Scope Improvements and Practical Expedients 2016-20, Technical Corrections and Improvements to Topic 606 No. 2017-13, Amendments to SEC Paragraphs Pursuant to the Staff Announcement at the July 20, 2017 EITF Meeting and Rescission of Prior SEC Staff Announcements and Observer Comments (SEC Update) No. 2018-18, Collaborative Arrangements (Topic 808): Clarifying the Interaction between Topic 808 and Topic 606 On April 1, 2018, the Company adopted Topic 606, using the modified retrospective transition method applied to those contracts which were not completed as of April 1, 2018. Results for reporting periods beginning after April 1, 2018 are presented under Topic 606, while prior period amounts have not been adjusted and continue to be reported in accordance with the Company’s our historic accounting policy. Adoption of Topic 606 did not have a significant impact on recorded revenue in the three and nine months ended December 31, 2018. See Note 5 – Revenue In November 2016, the FASB issued ASU No. 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash (a consensus of the FASB Emerging Issues Task Force In July 2017, the FASB issued ASU No. 2017-11, Earnings Per Share (Topic 260); Distinguishing Liabilities from Equity (Topic 480); Derivatives and Hedging (Topic 815): (Part I) Accounting for Certain Financial Instruments with Down Round Features; (Part II) Replacement of the Indefinite Deferral for Mandatorily Redeemable Financial Instruments of Certain Nonpublic Entities and Certain Mandatorily Redeemable Noncontrolling Interests with a Scope Exception 2017-11”). 2017-11 2017-11 2017-11 : Long-Term Debt Accounting Pronouncements Pending Adoption In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842) 2016-02”). An entity is permitted to elect certain optional practical expedients for transition to the New Lease Standard. The Company elected the package of practical expedients that allows it to not reassess 1) whether any expired or existing contracts are or contain leases, 2) the lease classification for any expired or existing leases, and 3) initial direct costs for any expired or existing leases. The Company will not elect the practical expedient to use hindsight when determining the lease term. The New Lease Standard also provides certain optional accounting policy elections related to an entity’s ongoing lease accounting, which can be elected by class of underlying asset. For real estate, vehicles, computers, and office equipment, the Company elected the short-term lease exception whereby the Company will not recognize a lease liability or right-of-use non-lease non-lease The adoption of the New Lease Standard resulted in the recognition of lease liabilities of $13.5 million and right-of-use 2016-02

Fair Value Disclosures [Text Block]	NOTE 7: FAIR VALUE OF FINANCIAL INSTRUMENTS The Company’s assets, measured and recorded at fair value on a recurring basis, may consist of money market funds which are included in cash and cash equivalents in the Condensed Consolidated Balance Sheets and are valued using quoted market prices (level 1 fair value measurements) at the respective balance sheet dates. No impairments charges were recognized for non-financial non-financial non-recurring Warrants and Warrant Liability The Company uses the Black-Scholes-Merton option valuation model for estimating fair value of common stock warrants. The expected life of warrants granted represent the period of time that they are expected to be outstanding. The Company determines the expected life based on historical experience with similar awards, giving consideration to the contractual terms, exercise patterns, and post-vesting forfeitures. The Company estimates volatility based on the historical volatility of the common stock over the most recent period corresponding with the estimated expected life of the award. The Company bases the risk-free interest rate used in the Black-Scholes-Merton stock option valuation model on the implied yield currently available on U.S. Treasury zero-coupon issues with an equivalent term equal to the expected life of the award. The Company has not paid any cash dividends on the common stock and does not anticipate paying any cash dividends in the foreseeable future. During fiscal year 2018, the Company began issuing common stock warrants in connection with the TCW Term Loan agreement. The warrants were initially accounted for as a liability and recorded at estimated fair value on a recurring basis due to exercise price reset provisions contained with the warrant agreements. As such, the Company estimated the fair value of the warrants at the end of each reporting period using a Black-Scholes valuation model. At the end of each reporting period, the Company recorded the changes in the estimated fair value during the period in other expense (income) in the condensed consolidated statements of operations and comprehensive loss. The table presented below is a summary of changes in the fair value of the Company’s Level 3 valuations for the warrant liability for the nine months ended December 31, 2018 and 2017 (in thousands): Warrant liability Balance, March 31, 2018 $ 272 Issuances 5,682 Settlements (176 ) Changes in fair value (942 ) Balance, December 31, 2018 $ 4,836 Balance, March 31, 2017 $ — Issuances 1,772 Settlements (1,063 ) Changes in fair value 33 Balance, December 31, 2017 $ 742 Long-term Debt The Company’s financial liabilities were comprised primarily of long-term debt as of December 31, 2018 and March 31, 2018. The Company uses significant other observable market data or assumptions (Level 2 inputs as defined in accounting guidance) that it believes market participants would use in pricing debt. The carrying value and fair value of the financial liabilities were primarily comprised of the following as of December 31, 2018 and March 31, 2018 (in thousands): As of December 31, 2018 March 31, 2018 Carrying Fair Value Carrying Fair Value Long term debt: (1) TCW Term Loan $ — $ — $ 90,424 $ 90,424 PNC Credit Facility — — 33,107 27,323 Senior Secured Term Loan 150,000 150,000 — — Total long-term debt $ 150,000 $ 150,000 $ 123,531 $ 117,747 (1) Fair value based on outstanding borrowings and market interest rates (level 2)

Commitments and Contingencies Disclosure [Abstract]
COMMITMENTS AND CONTINGENCIES	NOTE 10: COMMITMENTS AND CONTINGENCIES Commitments to Purchase Inventory The Company uses contract manufacturers for its manufacturing operations. Under these arrangements, the contract manufacturer procures inventory to manufacture products based upon management forecast of customer demand. The Company has similar arrangements with certain other suppliers. The Company is responsible for the financial impact on the supplier or contract manufacturer of any reduction or product mix shift in the forecast relative to materials that the third party had already purchased under a prior forecast. Such a variance in forecasted demand could require a cash payment for inventory in excess of current customer demand or for costs of excess or obsolete inventory. As of December 31, 2018, the Company had issued non-cancelable Legal Proceedings On July 22, 2016, Realtime Data LLC d/b/a IXO (“Realtime Data”) filed a patent infringement lawsuit against Quantum in the U.S. District Court for the Eastern District of Texas, alleging infringement of U.S. Patents Nos. 7,161,506, 7,378,992, 7,415,530, 8,643,513, 9,054,728, and 9,116,908. The lawsuit has been transferred to the U.S. District Court for the Northern District of California for further proceedings. Realtime Data asserts that the Company has incorporated Realtime Data’s patented technology into its compression products and services. Realtime Data seeks unspecified monetary damages and other relief that the Court deems appropriate. On July 31, 2017, the District Court stayed proceedings in this litigation pending decision in Inter Partes Review proceedings currently before the Patent Trial and Appeal Board and relating to the Realtime patents. That stay remains pending. The Company believes the probability that this lawsuit will have a material adverse effect on its business, operating results or financial condition is remote. In February 2018, two putative class action lawsuits were filed in the United States District Court for the Northern District of California against the Company and two former executive officers (the “Class Action”). The lawsuits were consolidated on May 16, 2018. The Class Action plaintiffs sought unspecified damages for certain alleged material misrepresentations and omissions made by the Company in connection with its financial statements for its fiscal year 2017. On December 25, 2018, the Court granted permission to plaintiffs in the action to file an Amended Consolidated Complaint. Before the plaintiffs filed their amended consolidated complaint, the parties met with a mediator to discuss a potential settlement of the case. On February 20, 2019, the parties reached a settlement in principal; under the terms of the settlement, the Company agreed to pay $8.2 million to plaintiffs. The amount includes all of plaintiffs’ attorneys’ fees, and the full amount will be paid by the Company’s directors and officers liability insurance carriers. A Stipulation of Settlement was signed by the Parties on June 28, 2019, and the Court granted preliminary approval on July 26, 2019. A hearing on final approval of the settlement has been scheduled for November 14, 2019. In May 2018, two shareholders filed litigation in California Superior Court for Santa Clara County on behalf of Quantum against several current and former officers and directors of the Company. A third action brought by a shareholder on behalf of Quantum was filed on March 4, 2019. These three lawsuits (the “Derivative Litigation”), which were consolidated by the Court, alleged, inter alia In February 2018, the Company received a document subpoena from the SEC requesting information pertaining to the Company’s financial statements for the period April 1, 2017 through the date of the subpoena. The Company responded to that subpoena. In August 2018, the Company received a second subpoena requesting similar documents for the period April 1, 2015 through the date of the subpoena. The Company understands that the SEC’s investigation relates to the facts and circumstances described in the Explanatory Paragraph and Note 2: Restatement Other Matters Additionally, from time to time, the Company is a party to various legal proceedings and claims arising from the normal course of business activities. Based on current available information, the Company does not expect that the ultimate outcome of any currently pending unresolved matters, individually or in the aggregate, will have a material adverse effect on its results of operations, cash flows or financial position.

SUMMARY OF SIGNIFICANT ACCOUN_2

SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Policies)	9 Months Ended
	Dec. 31, 2018
Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The accompanying interim unaudited condensed consolidated financial statements of the Company have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim financial information. All intercompany balances and transactions have been eliminated. Certain information and footnote disclosures normally included in annual financial statements have been condensed or omitted. The Company believes the disclosures made are adequate to prevent the information presented from being misleading. However, the accompanying unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto included within the Company’s most recent Annual Report on Form 10-K filed with SEC on August 6, 2019, which includes the audited and consolidated financial statements for the Company’s fiscal years ended March 31, 2019, March 31, 2018 and March 31, 2017. The accompanying unaudited condensed consolidated financial statements reflect all adjustments (consisting only of normal and recurring items) necessary to present fairly the Company’s financial position as of December 31, 2018 and the results of operations, cash flows, and changes in stockholder’s deficit for the nine months ended December 31, 2018 and 2017. Interim results are not necessarily indicative of full year performance because of the impact of seasonal and short-term variations.
Use of Estimates	Use of Estimates The preparation of these condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions. Certain accounting estimates involve significant judgments, assumptions and estimates by management that have a material impact on the carrying value of certain assets and liabilities, disclosures of contingent assets and liabilities and the reported amounts of revenues and expenses during the reporting period, which management considers to be critical accounting estimates. The judgments, assumptions and estimates used by management are based on historical experience, management’s experience and other factors, which are believed to be reasonable under the circumstances. Because of the nature of the judgments and assumptions made by management, actual results could differ materially from these judgments and estimates, which could have a material impact on the carrying values of the Company’s assets and liabilities and the results of operations.
Fair Value Measurements	Fair Value Measurements The fair value of financial instruments is based on estimates using quoted market prices, discounted cash flows or other valuation techniques. Those techniques are significantly affected by the assumptions used, including the discount rate and the estimated timing and amount of future cash flows. Therefore, the estimates of fair value may differ substantially from amounts that ultimately may be realized or paid at settlement or maturity of the financial instruments, and those differences may be material. Accordingly, the aggregate fair value amounts presented may not represent the value as reported by the institution holding the instrument. The Company uses the three-tier hierarchy established by U.S. GAAP, which requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value to determine the fair value of its financial instruments. This hierarchy indicates to what extent the inputs used in the Company’s calculations are Level 1: Unadjusted quoted prices in active markets for identical assets or liabilities. Level 2: Other than quoted prices that are observable in the market for the asset or liability, either directly or indirectly, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or model-derived valuations or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. Level 3: Inputs are unobservable and reflect management’s estimates of assumptions that market participants would use in pricing the asset or liability.
Recently Adopted Accounting Pronouncements	New Accounting Pronouncements Adopted in Fiscal 2019 In May 2014 the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606 No. 2015-14, Deferral of the Effective Date No. 2016-08, Principal versus Agent Considerations (Reporting Revenue Gross versus Net) No. 2016-10, Identifying Performance Obligations and Licensing No. 2016-02, Narrow-Scope Improvements and Practical Expedients 2016-20, Technical Corrections and Improvements to Topic 606 No. 2017-13, Amendments to SEC Paragraphs Pursuant to the Staff Announcement at the July 20, 2017 EITF Meeting and Rescission of Prior SEC Staff Announcements and Observer Comments (SEC Update) No. 2018-18, Collaborative Arrangements (Topic 808): Clarifying the Interaction between Topic 808 and Topic 606 On April 1, 2018, the Company adopted Topic 606, using the modified retrospective transition method applied to those contracts which were not completed as of April 1, 2018. Results for reporting periods beginning after April 1, 2018 are presented under Topic 606, while prior period amounts have not been adjusted and continue to be reported in accordance with the Company’s our historic accounting policy. Adoption of Topic 606 did not have a significant impact on recorded revenue in the three and nine months ended December 31, 2018. See Note 5 – Revenue In November 2016, the FASB issued ASU No. 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash (a consensus of the FASB Emerging Issues Task Force In July 2017, the FASB issued ASU No. 2017-11, Earnings Per Share (Topic 260); Distinguishing Liabilities from Equity (Topic 480); Derivatives and Hedging (Topic 815): (Part I) Accounting for Certain Financial Instruments with Down Round Features; (Part II) Replacement of the Indefinite Deferral for Mandatorily Redeemable Financial Instruments of Certain Nonpublic Entities and Certain Mandatorily Redeemable Noncontrolling Interests with a Scope Exception 2017-11”). 2017-11 2017-11 2017-11 : Long-Term Debt Accounting Pronouncements Pending Adoption In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842) 2016-02”). An entity is permitted to elect certain optional practical expedients for transition to the New Lease Standard. The Company elected the package of practical expedients that allows it to not reassess 1) whether any expired or existing contracts are or contain leases, 2) the lease classification for any expired or existing leases, and 3) initial direct costs for any expired or existing leases. The Company will not elect the practical expedient to use hindsight when determining the lease term. The New Lease Standard also provides certain optional accounting policy elections related to an entity’s ongoing lease accounting, which can be elected by class of underlying asset. For real estate, vehicles, computers, and office equipment, the Company elected the short-term lease exception whereby the Company will not recognize a lease liability or right-of-use non-lease non-lease The adoption of the New Lease Standard resulted in the recognition of lease liabilities of $13.5 million and right-of-use 2016-02
