• This FID can be presented if a Write command is issued to a WORM tape cartridge that is at a point on
the tape that was already written once.
• This FID can be presented for an invalid and unsupported SCSI command or parameter, which is a SCSI
application program software problem. Sense data is sent to the host.
• This FID also can be presented for a drive operator procedural problem.
The service representative must look in the drive error log for any ATTN DRV messages (which might
cause the FID FF to be sent to the host with sense data). If any of these ATTN messages are present in the
error log, use that data to complete further isolation for the FID FF cause.
Suspected microcode problem
1. Press Reset on the service panel.
2. From the service panel, press Change Mode .
3. Select CE Offline Mode > Verify Fix/Diag > Test Device.
4. Load a CE scratch tape when you are prompted to load a tape cartridge.
5. If you get a FID, go to "FID entry point" on page 6 to analyze the FID.
6. If the drive tests successfully complete, the problem might be a microcode problem or an intermittent
hardware problem.
Go to "Problem determination" on page 182 or "FID 83 or E5 - Microcode problem" on page 239 for
problem determination.
7. If the failure still occurs, collect as much information as you can from the customer, and contact your

Trap Taken message is displayed on the operator panel. If an FID 83 or E5 occurs, it might overlay the
ATTN DRV message. The dump icon is still displayed, with the ATTN DRV message that exists behind the
dump icon.
Note: Normal error match traps are volatile and are lost if you press Reset, power OFF the device, or the
microcode recovery occurs (with Check-1, FMR, and so on). Saved error match traps cannot be lost by
completing a reset, and requires a special procedure for removal. See the "Removing the error match
trap" on page 247 procedure for details.
