Unable to read TIFF file with raster2pgsql

I am having some trouble with the raster2pgsql function (on a Windows 7 in the OSGeo4W shell). I am receiving the error "Unable to read raster file". I can import shapefiles, ok using org2org so I know that the connection works, it just does not work for the raster2pgsql function.

To retrace my steps, I first changed the directory from m:/> to the folder containing my raster:

cd M:UsersuserIDDocumentsRKoala_Projkoala_datakoala_information_basehabitat_suitability

I then check the files within the directory using >dir to see what the raster is called. From this, I receive a list of the one raster in this folder and the affiliated files, such as:
koala_raster.tif

I then try to use the raster2pgsql to import this raster to the above directory in postgresql:

raster2pgsql -s 4283 -I -C -t 100x100 koala_raster.tif public.khsm │
psql -h localhost -p 1234 -d koala -U postgres

I have also tried:

raster2pgsql -s 4283 -I -C -t 100x100 *.tif public.khsm │
psql -h localhost -p 1234 -d koala -U postgres

From these queries, I receive the error "Unable to read raster file".

However, rather than the file that this error refers bring named "koala_raster.tif" it prints "._koala_raster.tif". I am not sure what the "._" at the beginning of my raster refers to, or how to fix this problem I am having.

I have looked for fixes in

• Uploading raster format(*.tif) to postgis through raster2pgsql
• Cannot upload an IMG file into PostGIS using raster2pgsql
• and the help files

However, I still have not found a solution that fixes my problem.
