摘要： A method and apparatus are provided for implementing secure erase for solid state drives (SSDs). An encryption key is used to encrypt data being written to SSD. A controller identifies a key storage option, and responsive to the identified key storage option, stores a key for data encryption and decryption. The controller deletes the key within the SSD responsive to the identified key storage option, ensuring that once the key is deleted, the key is not recoverable and data is effectively erased.

摘要： Patterned-media magnetic recording disks are made from a master template that has nondata regions that contain a pattern of one or more discrete nondata islands and discrete gaps, with the pattern representing a scrambled number. All disks made from the master template, or from replica molds made from the master, will have the same patterns. When the disks are DC-magnetized so that all the nondata islands are magnetized in the same direction, these patterns will include one or more of discrete magnetized nondata islands and discrete nonmagnetic gaps that are scrambled in a pseudo-random manner. During operation of the disk drive the patterns are detected by the read head and interpreted within the disk drive using knowledge of the pseudo-random scrambling function, so that reading and writing of data can occur in the conventional manner. If the disks are copied in an attempt to replicate the master template, the resulting disks will be inoperable in a disk drive because of the scrambling.
摘要翻译：图案化介质磁记录盘由主模板制成，该主模板具有包含一个或多个离散非数据岛和离散间隙的图案的非数据区域，其中图案表示加扰数字。由主模板制成的所有磁盘或从主模块制作的副本模具将具有相同的模式。当磁盘被直流磁化使得所有的非磁盘岛都以相同的方向被磁化时，这些模式将包括以伪随机方式加扰的离散磁化非磁盘岛和离散非磁性间隙中的一个或多个。在磁盘驱动器的操作期间，通过读取头检测图案并使用伪随机加扰函数的知识在磁盘驱动器内进行解读，从而以常规方式发生数据的读取和写入。如果复制磁盘以复制主模板，则由于加扰，生成的磁盘将无法在磁盘驱动器中运行。

摘要： A verifiable security mode is provided for securing data on a storage device, such as a hard disk drive. When the verifiable security mode is enabled, only authenticated accesses to data stored on the storage device are permitted after entering a password. An end user is prevented from disabling the verifiable security mode. The verifiable security mode can be set to allow or disallow an administrator from disabling the verifiable security mode. The verifiable security mode can be implemented, for example, in firmware on a hard disk drive (HDD).

摘要： A shingled magnetic recording hard disk drive that uses writeable cache tracks in the inter-band gaps between the annular data bands minimizes the effect of far track erasure (FTE) in the boundary regions of annular data bands caused by writing to the cache tracks. Based on the relative FTE effect for all the tracks in a range of tracks of the cache track being written, a count increment (CI) table or a cumulative count increment (CCI) table is maintained. For every writing to a cache track, a count for each track in an adjacent boundary region, or a cumulative count for each adjacent boundary region, is increased. When the count value for a track, or the cumulative count for a boundary region, reaches a predetermined threshold the data is read from that band and rewritten to the same band.
