Hmm, depending on the problem the disk has and how the controller is implemented the behavior on fatal errors can be unpredictable, especially when DMA is involved (some controllers just lock the bus completely so our timeout code wont get a chance). If you switch the disk to PIO mode, does that help any ? -- -SørenReceived on Wed May 11 2005 - 11:28:15 UTC
