My best guess is that like Gr\'egoir's CD-ROM, your wangtek is claiming to support a speed it cannot. We find this out in DV, but not until we've gone through all the error paths. The quick fix is simply to set the bios to whatever the tape eventually configures with (although you'll need the current patch set to make that work properly). James
