I am Running Windows 2003 Std with Netbackup 6.0 MP3
So far it has run faily consistenly however just this week the jobs have all been failing due to "The request could not be performed because of an I/O device error". Netbackup is just simply not writing to the tapes anymore. I thought it may be a bad drive but I've tried numerous tapes even new ones and cleaned the drive. The tape drive is a standalone Dell Powervault 114T LTO3. I've called tech support but so far no luck.

Please send any remedies my way!

Try upgrading the firmware on the tape drive itself and that should fix it.

Try using the builtin ntbackup utility. If that doesn't work get the drive serviced.

The problem may be resolved by isolating the tape device on an Integrated Drive Electronics (IDE) controller in the computer. For example, if the tape and a CD-ROM are connected to the same IDE controller on the motherboard, move the CD-ROM to a secondary IDE controller.

I/O error is usually hardware.

Make sure the Removable Storage service is disabled on the media server.  it interferes with NBU (although I usually saw 'rewind caused by external event' errors).

Other than that, I too would be pointing to a hardware issue.  Either the drive, the SCSI controller or the cable.  rindi suggested using the inbuilt ntbackup - if it fails, you've proven a hardware or driver fault. if it works ok, you've proven it's likely a NBU fault.
