I see this with a WangDAT-3400dx and a bt946c controller. I increased the rewind/eject timeout in st.c and increased the "abort" timeout in bt742a.c. With timeout increases, if the system is quiet when you close/rewind the drive then nothing wild happens. If you use unmodified st/bt742a then the disks will all get bit sprayed every single time you rewind/close the tape. Regards, Mark Hittinger bugs@win.net
