[Gdal-dev] gdal_translate error

I'm trying to convert some adf files to ascii (AAIGrid format).  I am 
using the following command line:

./gdal_translate -of AAIGrid 

I get the following error everytime I try:

Input file size is 76056, 62770
0...10...20.ERROR 1: IReadBlock failed at X offset 0, Y offset 3405
ERROR 1: GetBlockRef failed at X block offset 0, Y block offset 3405

The adf files load fine in ArcMap.  The file is about 6.1GB when it 
dies, and I have plenty of space left on the drive.  I've ensured there 
is no LFS or large file problems on the linux system (as the 6.1GB file 
size should prove).  My guess is that gdal thinks the file is corrupted 
in some way, but since ArcMap is able to open it fine, I don't know how 
accurate that is.

Does anyone have some ideas or input as to what might be causing this 
problem?  Thanks,
