It must be the way it access the device, that causes the problem. I suggest trying the following: 1) Create a filesystem covering the whole disk, 2) Fill up the disk creating a file the size of the filesystem on it. 3) have bcwipe operate on the file instead of the raw device. I assume it does this. I am not familiar with bcwipe... Nikos
