Why do you want to do the tar then the split and then the copy.
What's wrong with tar cv2 <filename.or.directory>
(Assuming 2 is the proper number in your /etc/defaults/tar file)
Passed the media size and blocking factor tar will gracefully put
everything you need out there.
There is a tarskip program on the net (a year or so ago) allowing
you to go past any bad files.
As to floppy errors, use good quality floppies, and backup often.
You could also re-read the floppies to make sure they were okay.
I do this on archiving. I tar them off, read them back in on
another machine. When I know the floppy is readable I remove the
originals. If it is an important file I make two copies.
