Happens when you try to record on the system disk / system partition or on a partition of the first (Master) HD. This error also occurred when an old SCSI driver (1999) has been installed by Windows 98 itself, and no update was run.- Copy the session to a different (non-system) drive- Do not use a partition of the primary master HD (e.g. master HD has been partitioned into C:\ and D:\, where C:\ is the system partition and D:\ is an extended partition)- Update your SCSI driver
