I tried tarring a bit to my TZ87, giving the following results:

------ Write errors log page ------

Corrected errors without substantial delay:  0 
Corrected errors with possible delay      :  0 
Total errors                              :  11 
Total errors corrected                    :  11 
Total times correction algorithm processed:  0 

------ End of write errors log page ------

------ Compression log page ------

Read compression ratio (* 100 %)       :  0 
Write compression ratio (* 100 %)      :  100 
Total host Mbytes reads                :  0 
Total host kbytes read residual        :  0 
On tape Mbytes read                    :  0 
On tape kbytes read residual           :  0 
Host requested Mbytes written          :  1169 
Host requested kbytes written residual :  854016 
On tape Mbytes written                 :  1169 
On tape kbytes written residual        :  0 

------ End of compression log page ------

The error rate is quite different as you can see. I'm studying the
firmware spec to see if I can get more info from the drive. 

In fact I am sure it can be done, it's just that I have to find out
how to get a 'scsi' script to do it. 

In the meantime you might also be interested in trying 'DLTTOOLS' from
the Quantum website. You should be able to test the drive a bit more.
(It's a DOS tool, sorry 'bout that)
