Notification: Replacement Procedure for Classified RHDDs

Pursuant to the requirements of U. S. Code of Federal Regulations (CFR) 1-101, and Executive Order 12829, as implemented under the National Industrial Security Program, governing receipt and storage of classified material, General Dynamics C4 Systems (GDC4S) is prohibited by law from receiving removable hard disk drives (RHDDs) that contain or were used to process information classified by the Government as SECRET, TOP SECRET, and/or SPECIAL ACCESS. Consequently GDC4S cannot physically evaluate such RHDDs for potential repair or replacement under the CHS-4 Warranty or otherwise.

However, Army users of RHDDs purchased under the CHS-4 contract may obtain warranty support for "classified" RHDDs through the following procedure: 

1. call the CHS-4 Warranty HotLine [877-247-7711] to open a Repair Order

2. physically remove and destroy the RHDD platters from the RHDD container in accordance with Army policies and procedures

3. return the empty RHDD container to a GDC4S Regional Support Center (RSC) together with a letter certifying that "The accompanying RHDD, purchased under the CHS-4 prime contract, was used to process information classified by the Government as Secret and/or Top Secret. Due to the failure of the RHDD the internal platters were removed and the empty container is being returned for RHDD replacement under warranty

Upon receipt the RHDD General Dynamics will process the Repair Order and replace the RHDD at no cost to the Army within 60-days.
