I have been unable to write to 600A tapes in my Archive Viper 2150S.  I
have had mixed results trying to READ 600A tapes in the same drive --
I suspect it is a Unix problem rather than a drive problem -- the troubles
involved tar and cpio, but dd worked OK.  I have been using 6150 tapes
on a regular basis.
