Cheyenne's ArchServ provides file verification. I do not know if they
have "certified" their product for your version of UNIX. You can find
them at http://www.cheyenne.com/.
We have had a disaster on our DEC Alpha 400 involving this problem. It
appears that the 4mm tape drive was creasing the tapes on write in a
random way. Thus when they could not be read and used for backup. We lost
a lot of data and had to manually reconstruct our files. We are now
actively looking for a verification product that will work on our
platform. Any ideas any one?
