I'd like to use a Toshiba (USB powered) portable hard drive to back-up/transfer some recordings. This is formatted NTFS and looking at the disk under Windows 7, it can be reformatted to exFAT (no sign of FAT32) or default NTFS only. Will Easeus Partition enable me to reformat the disk to EXT3 for it to be used to transfer recordings, including some larger than 4GB? If I choose to later, can I reformat the disk back to NTFS (losing the data of course).
