My system iMac with internal HD, Lightroom 4.4 and two external drives for files/data ("My Book" and "My Book Backup")
These two drive are desktop drive. I have purchases a portable drive "My Passport" to be used with my iMac and MacBook.
I have copied on this portable drive named "My Passport" all folders with images and Lightroom folder with Catalogs.
To start Lightroom from the portable drive ("My Passport") I have double-clicked "Lightroom 4 Catalog.lrcat" on the external drive. Lightroom opened, however have not recognized the portable drive with name "My Passport" and nothing to see.
I have logoff the Lightroom, renamed "My Passport" to "My Book", the name, which Catalog knows is and everything is working. However I could not return to the portable drive its original name "My Passport" - no Rename available for the drive.
How I change the external drive temporary given name "My Book" to its permanent future name "My Passport" ???
Thank you for the help
