I am getting error messages that don't make much sense. They would lead me to beleive that the tape is bad... I guess. Yet, I have a hard time beleiving that the two out of four tapes is bad. issuing an 'mt erase' it get an input/output error. below are the kernel messages. could two tapes suddenly just become 'bad'? Since these are ait tapes and have a 64k ram buffer, I'm wondering if there may be some bad data there and if there is a way to clear it... The tape unit is a sony sdx300c. I've updated it to the latest firmware. Its attached to an adaptec 2940wide. Any advice would be greatly appreciated. =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D dmesg =3D=3D=3D=3D=3D=3D=3D=3D= =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D =20 =2E.. lots of stuff deleted ...
