Field: Computer technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 0:
1. A method, comprising:
determining a data storage device to decompose and recompose;
setting, responsive to determining to decompose and recompose the data storage device, a flag indicating that flushing a virtual-to-physical (V2P) mapping table of the data storage device is unnecessary for a next reset command;
downloading a firmware update to the data storage device, wherein the data storage device includes a plurality of non-volatile memory devices;
activating the firmware update in the data storage device;
receiving the next reset command at the data storage device, wherein reset commands normally include flushing the V2P mapping table from a volatile memory in the data storage device to at least one non-volatile memory device of the plurality of non-volatile memory devices in the data storage device;
determining, prior to executing flushing of the V2P mapping table for the next reset command, whether the flag is set;
forgoing, responsive to determining that the flag is set and execution of the next reset command, flushing the V2P mapping table to the at least one non-volatile memory device; and
completing the reset command without flushing the V2P mapping table, wherein:
the V2P mapping table is cleared from the volatile memory by a power cycle of the reset command; and
a provisioning time of decomposing and recomposing the data storage device is reduced.
