Abstract
A method is provided in which a volume allocation table (VAT) is constructed in a system memory on the basis of those files stored on a plurality of disks. In constructing the VAT of the system memory, contiguous (i.e., single run) files are first allocated to a first set of locations on the disks, and then non-contiguous (i.e., multiple run) files are allocated to a second set of locations on the disks. Upon building the VAT of the system memory, copies of it are written respectively to the disks so that the contiguous and non-contiguous files can be allocated to the first and second set of locations, respectively.
