General question when updating the audiophile versions on the original USB disk. Is it normal to run the update on the original BIAB2015 USB disk version?

I ask as normally it's best to keep the original update media as delivered but as it happens I prefer to use the original USB disk so all the WAV files don't need to be copied to my PC HDD.
I did my updates direct on the original USB disk for BIAB2014 but thought I'd ask this time in case this time around I corrupt the original USB media.

I can make a back up of the original media to my NAS drive but not everyone has this option so curious as to the PG Music recommendation for audiophile users.

Thanks for any guidance smile
