Ayrat,

Everything else looks like it might work though you might want to set
STATUS to DEFAULT to make sure that old chestnut isn't the issue.  But your
world file is all messed up.  If you want a raster with 0-600 extents in each
dimension you should be using the following coefficients:

1
0
0
-1
0.5
599.5

The 1 is the size of a single pixel in X, the -1 is the size of a single
pixel in Y, the 0.5 is the X location of the center of the top left pixel.
The 599.5 is the Y location of that center of pixel.

Good luck,
