Method to write information to an information storage medium using a network attached storage device

An article of manufacture capable of communicating with an information storage medium, comprising a computer readable medium having computer readable program code disposed therein to write information to said information storage medium, the computer readable program code comprising a series of computer readable program steps to effect:

• opening a file with write permission;
• locating a first Extent Descriptor associated with said file, wherein said Extent Descriptor comprises a physical block staffing address;
• determining if said physical block starting address comprises a fictitious address which does not point to allocated physical storage blocks comprising a contiguous region of data;
• operative if said physical block starting address comprises a fictitious address that does not point to allocated physical storage blocks comprising a contiguous region of data, allocating one or more first storage blocks to said file;
• and
• writing said file to said one or more first storage blocks.

A computer program product usable with a programmable computer processor and encoded in an information storage medium, wherein said computer program product is disposed in a network attached storage device capable of communicating with said information storage medium, comprising:

• computer readable program code which causes said programmable computer processor to open a file with write permission;
• computer readable program code which causes said programmable computer processor to locate a first Extent Descriptor associated with said file, wherein said Extent Descriptor comprises a physical block starting address;
• computer readable program code which causes said programmable computer processor to determine if said physical block starting address comprises a fictitious address which does not point to allocated physical storage blocks comprising a contiguous region of data;
• computer readable program code which, if said physical block starting address comprises a fictitious address that does not point to allocated physical storage blocks comprising a contiguous region of data, causes said programmable computer processor to allocate one or more first storage blocks to said file;
• and
• computer readable program code which causes said programmable computer processor to write said file to said one or more first storage blocks.
