A method, executed by a computer, for recording data includes splitting a file into sequential extents, reordering the sequential extents into non-sequential extents, writing the non-sequential extents to a storage medium, writing dummy data to the storage medium, and writing extent placement information corresponding to a placement for the non-sequential extents to the storage medium. A computer program product and computer system corresponding to the above method are also disclosed herein.
