I used to do this, wasting time and increasing wear on my tape drive, 
until I discovered that LTO tape drives (hopefully other modern drives 
as well), read the data back as it is being written (the read head is 
positioned behind the write head). If an error is detected, it writes a 
second copy of the data. These will appear as rewrite errors in the 
drive error log.
