I have a USB drive registered for KDL-40EX720. Now I would like to use again with a PC. I have unregistered the USB drive, but it is still inaccessible with PC. Meaning Vista does not assign a letter for it, is unable to format. Is the once registered disk always married with Bravia?
I would also like to partition the drive so that I can keep my backups in one partition, and use USB recording for the another partition. But if it's too advanced, I can manage without.
