Thanks for your fast reply. :)
Is FATXplorer the best soft (faster, reliable) to mount 360 HDD partitions in windows (viadirect sata connection) to backup/restore data?
I did a previous restore via ftp and it take overnight to complete for "only" 200 GB of a 256 gb HDD... now for a 2tb HDD it...
Can i add the hddx partition and compatibility folder to it in a working 2tb hdd (a lot of games installed) in rgh'ed 360 WITHOUT backup and restore all the data in hdd1 partition?
I mean is backup and restore mandatory?
