It's probably best to assume that there's a significant chance that only a data recovery shop will be able to read a DDS1 tape if the drive dies and it was from the DDS1 era. That's not to say you can't transfer data with them, but since the road to failure generally starts with misaligned heads, tapes written at the end of a drives life are often bad. Having said that, modern helical scan devices are quite solid and my Sony DDS3 drive has survived much more time and use then the old HP DDS1s we used for backups in college. -- Brooks --=20 Any statement of the form "X is the one, true Y" is FALSE.
