I'll look at that manual page too. After the post, we did some more tinkering and we got T-ATT SCT to work and it appears we're able to see all of the data on the tapes.
I'm glad you mentioned dd. We were trying to dd the tape to an image, but were running into some unusual results. Maybe you could help with what we may have been missing? We were using this command: dd if=/dev/st0 of=/tmp/tape.dat bs=16384 We basically got a message saying 3 records in, 3 records out. When we looked at the "tape.dat" file, it was only 48kb in size. When we T- ATT that file and did a T-READ it only showed the accounts that the filesave on the tape created. Any suggestions?
