running recalibration script has downgraded firmware rev

[Dennis Lee_5]

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.

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.
