Hi Even,

This is not related to disk space. I just monitored with df and there 
were no problems, and not even a close call on space.

gdalwarp creates the file and actually writes some to it:

$ gdalwarp --config CPL_TMPDIR . -t_srs EPSG:900913 -of GTiff -co 
TILED=YES -co COMPRESS=JPEG -co PHOTOMETRIC=YCBCR Saraji_South.ecw 
Saraji_South-900913.tif
Creating output file that is 34551P x 32332L.
Processing input file Saraji_South.ecw.
0...10...20..ERROR 1: Could not perform Read/Write on file

ls -l Saraji_South-900913.tif
-rw-r--r--  1 woodbri woodbri  57130007 2012-12-17 17:43 
Saraji_South-900913.tif


I renamed the file and run the command again, it creates another file of 
exactly the same size.

-rw-r--r-- 1 woodbri woodbri  57130007 2012-12-17 17:57 
Saraji_South-900913a.tif
-rw-r--r-- 1 woodbri woodbri  57130007 2012-12-17 17:43 
Saraji_South-900913.tif

And they appear to byte for byte identical using cmp.

Thanks,
