For a small project I had almost 30 years ago (definitely a non-IBM 
project) I purchased an Overland Tape unit. It was SCSI attached. I also 
had a DVD writer attached to the PC and did a fair bit of coding to make 
software that would read a 9-track tape and write the data on DVD. 
Included were utilities to recover the data in a variety of formats and 
write a new 9-track tape if that was what was required. The goal was to 
help with "archived" data on 9-track tapes. An odd characteristic of the 
programming was to accept data blocks that caused read errors (after a 
number of retrys, of course) and write the data on the DVD with an 
appropriate flag in my header for the data record. While writing the 
programs I assumed this was an oddball feature, not realizing how many 
data errors we would encounter when reading "archived" tapes. In the 
locations where we used the "product" the old 9-track tapes were stored in 
appropriately controlled areas, etc, etc. No obvious customer sloppy 
storage or handling. 

You might want to give serious thought about handling a fair number of 
errors when reading old old old tapes! The Overland Tape unit worked well, 
especially if the programming was such that it did not need to stop 
between records. I did not associate the data errors with a drive problem; 
it handled "newer" data tapes without problems.
