running recalibration script has downgraded firmware rev

hi there,
i ran a device analysis test using the HP L&TT. it suggested i run the recalibration script. the test ran successfully, but i think the script has also downgraded the firmware. i was just wondering if anyone else has encountered this, and if upgrading the firmware (again) to the newest revision will have any effect on the recalibration.
thank you.
-Dennis

additional info:
drive: C1537A
firmware rev: L005
backup software: veritas backup exec 8.6
symptoms that led to running recalibration script: got following message in backup log

Re: running recalibration script has downgraded firmware rev

The process of recalibration does write a new firmware image to the drive. There is one particular firmware image associated with recalibration - thus it is possible to have your firmware downgraded as a result of recalibration. I will investigate this further and post an update.

It should be safe to update the firmware back to the latest after the recalibration is completed.
