Embodiment Construction

[0019] As noted above, storage devices may attempt to protect files from deletion by designating files as read-only or hidden. However, under this protection scheme, files can still be corrupted. To improve protection of files, a storage device may designate files as part of an event partition in response to determination of an event. As discussed in more detail below, events may be based on data generated externally of the storage device. When the storage device is notified of an event (either by a command received by the host device or by a determination by the storage device), files may be designated as part of the event partition.

[0020] An event partition may include a different set of access rules than other partition(s) in storage. For example, writing to and / or deletion of files designated as part of an event partition may be disabled or may be allowed only in limited circumstances. An example of a limited situation may include analyzing the age of the storage dev...

Abstract

A system and method are disclosed for an event lock storage device. The storage device includes a user partition and an event partition (which may be associated with an event). The storage device receives data from a host device, and stores the data in the user partition. In response to receiving an indication of an event, the storage device may designate the data as part of the event partition. The event partition may include a set of access rules that is different from the user partition, such as more restrictive rules for modification or deletion of a file containing the data.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of US Application No. 14 / 292,047, filed May 30, 2014, the entire contents of which are hereby incorporated by reference. technical field [0003] The present application generally relates to managing data in storage devices. More specifically, the present application relates to storage devices restricting access to files or deleting files in response to the occurrence of predetermined events. Background technique [0004] The storage device may store files using a file system. When it is desired to protect a file from deletion, the file system can set the file to be read-only or hidden. In this way, files are less likely to be accidentally or intentionally deleted. However, under this protection scheme, files may still be corrupted, such as by altering file system tables. Contents of the invention [0005] Systems and methods for event-locking storage devices are disclosed. Ac...
