Bob,
Thanks for the speedy reply. I'm going to try and get the original scan files, but unfortunately they are on some obsolete tape media (the scans are pretty old), so that's going to be a process.
Let me ask you about the likelihood of the two scenarios given that there are two other scans with the same problem. One of the scans was given on the same date and the other was given about five months later. I just want to make sure that there is a hearty chance that our original data has potential before I go looking for appropriate tape readers.
Thanks again
