It also fails with 2.4.20-8. > I tested cpio and dd in my system with 2.4.28 without finding any problems (both variable block mode and fixed block mode with 1024 byte blocks). Some additional information may help to solve your problem: - Fixed or variable block mode? What blocksize if fixed block mode? (Output of 'mt status' tells these.) - Tape drive and SCSI adapter make and model - Any tape messages in system log? - Debugging output from st. (You can enable debugging in st by editing the driver source (change '#define DEBUG 0' to '#define DEBUG 1') and recompiling the kernel/module. -- Kai - To unsubscribe from this list: send the line "unsubscribe linux-scsi" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
