Pasta,

This was presumably a GeoBigTIFF.  There was a project in the last few
years to extend the TIFF format to support 64bit addressing and the
resulting format variant is called BigTIFF.  It is supported by
libtiff 4.x (still in beta really), and GDAL 1.7 and on.

In brief, GDAL transparently supports traditional 4GB limited TIFF
and BigTIFF which supports much larger file sizes.

Best regards,
