FYI: This is the 3rd tape device...Seagate has sent this problem started after a Windows Update!
The Tape device model TC4200-091 DDS-4 has all the dip switches in the default position, ON. It's attached to a standard Adaptec 29160 scsi card and the scsi cable has the proper terminator on the last connector.
I have installed the latest 29160 card drivers from Adaptec. Uninstalled the tape device several times, installed two hot fixes from Veritas , downloaded and installed the newest device drivers from Veritas.
Can we attached screen shots? The problem is that the diag utility test electronically ok but fails on the read/write. In the removable storage the drive has a red X says it's not present yet it test out electronically and the cleaning tape works. Also in the Backup exec app the device show up as ready to use.
Thank you any ideas would be appreciated. Alex
