A non-copyable data storage disk (NCDisk) that may be used in a secure data storage system. Stored data items on the NCDisk may only be used through the data storage system, and cannot be copied to and used by any other devices. Digital data written to the NCDisk is automatically converted to a new format by the NCDisk itself before being stored on it. Similarly, when reading a data item out from the NCDisk, the NCDisk itself automatically converts the stored data item to a new data format that a reading device can recognize. Data conversion does not involve the computer operating system. The data conversion unit may include a chipset level 2 secure key management module that generates and manages the keys used for the data conversion.

Objects stored in a storage system (such as a file server system) are protected by multiple levels of validation. Each chunk of an object is associated with a chunk validator, and an object validator is computed for the object based on the chunk validators. The object validator is stored in the storage system and may be used at various times to validate the object, for example, upon a startup of the storage system, upon taking a checkpoint or “snapshot” of the status of the storage system, or at other appropriate times.

For protecting data within a data storage system, such as a hard disk drive, security enable mode is entered. In that mode, initialization data is moved from a first area of a disk to a second area of the disk with a location of the second area being randomly generated. The initialization data is then erased from the first area. Also, a first cipher for firmware and a second cipher for a disk are both changed into a randomly generated value. Later, access to the initialization data from the second area is granted in the security enable mode if the first and second ciphers are the same.
