Method and system for providing storage device file location information

A method for managing a storage device, the method comprising:

• in a storage device having a memory and a controller, wherein the storage device is operatively coupled with a host, the controller:
• receiving data from a host;
• in response to detecting a signature in a cluster of the received data, storing for future retrieval or transmitting back to the host the logical address within the memory of where the received data was written;
• and
• subsequent to storing or transmitting the logical address, receiving from the host a file system data structure query, the file system data structure query based on calculations associated with the stored or transmitted logical address, for access to portions of the file data structure stored on the storage device related to the stored or transmitted logical address.

A storage device comprising:

• a memory storing host files and a file system data structure containing information on a location of clusters for host files in the memory system;
• and
• a controller in communication with the memory, the controller configured to:
• receive a plurality of clusters for a particular file from the host, wherein only a first cluster of the particular host file includes a signature;
• and
• transmit cluster location data from the storage device in response to receiving the first cluster of the particular host file with the signature, the cluster location data comprising information on only a location in the memory of the first cluster of the particular host file.
