Debt Disclosure [Abstract]
Debt	4. Debt On March 8, 2012 (the “HGST Closing Date”), the Company, in its capacity as the parent entity and guarantor, Western Digital Technologies, Inc. (“WDT”), a wholly owned subsidiary of the Company, and Western Digital Ireland, Ltd. (“WDI”), an indirect wholly owned subsidiary of the Company, entered into a five-year credit agreement (the “Credit Facility”) with Bank of America, N.A., as administrative agent, swing line lender and letter of credit issuer, and certain other participating lenders (collectively, the “Lenders”). The Credit Facility provided for $2.8 billion of unsecured loan facilities consisting of a $2.3 billion term loan facility and a $500 million revolving credit facility. The only borrower under the term loan facility is WDI and the revolving credit facility is available to both WDI and WDT (WDI and WDT are referred to as “the Borrowers”). The Borrowers may elect to expand the Credit Facility by up to an additional $500 million if existing or new lenders provide additional term or revolving commitments. The obligations of the Borrowers under the Credit Facility are guaranteed by the Company and the Company’s material domestic subsidiaries, and the obligations of WDI under the Credit Facility are also guaranteed by WDT. During the three months ended September 27, 2013, WDT borrowed $500 million under the revolving credit facility. The term loans and the revolving credit loans may be prepaid in whole or in part at any time without premium or penalty, subject to certain conditions. As of September 27, 2013, the term loan facility and revolving credit facility had a variable interest rate of 2.18% and a total remaining outstanding balance of $2.4 billion. The Company is required to make principal payments on the term loan facility totaling $230 million a year for fiscal 2014 through fiscal 2016, and the remaining $1.3 billion balance (subject to adjustment to reflect prepayments or an increase to its term loan facility) is due and payable in full on March 8, 2017. The outstanding amount of the revolving credit facility is also required to be repaid by March 8, 2017. The Company intends to repay the revolving credit facility within one year; therefore, the outstanding balance of $500 million under the revolving credit facility is classified as a current liability on the condensed consolidated balance sheet. The Credit Facility requires the Company to comply with a leverage ratio and an interest coverage ratio calculated on a consolidated basis for the Company and its subsidiaries. In addition, the Credit Facility contains customary covenants, including covenants that limit or restrict, subject to certain exceptions, the Company’s and its subsidiaries’ ability to incur liens, incur indebtedness, make certain restricted payments, merge, consolidate or dispose of substantially all of its assets, and enter into certain speculative hedging arrangements and make any material change in the nature of its business. Upon the occurrence of an event of default under the Credit Facility, the administrative agent at the request, or with the consent, of the Required Lenders (as defined in the Credit Facility) may cease making loans, terminate the Credit Facility and declare all amounts outstanding to be immediately due and payable, require the cash collateralization of letters of credit and/or exercise all other rights and remedies available to it, the Lenders and the letter of credit issuer. The Credit Facility specifies a number of events of default (some of which are subject to applicable grace or cure periods), including, among other things, non-payment defaults, covenant defaults, cross-defaults to other material indebtedness, bankruptcy and insolvency defaults, material judgment defaults and a change of control default. As of September 27, 2013, the Company was in compliance with all covenants.
