Hi, I've run both -set and -dir backups on a Dell PV100T DAT72 drive. During the backup, I get 'afio: x bytes written. The operation was successful.' But after that, I see 'mt: /dev/st0: Inappropriate ioctl for device'
I get the same error when I try to restore. And whatever I try to restore doesn't appear to be written back onto the disk. I don't know if this helps, but if I do -toc, I get an error, but '-toc all' will show the tape contents.
