I will be using TI ver. 9.0 build 3677, but before I do that, please answer some questions of mine. I'm running a Sony VAIO Windows XP Media Center Edition. Internal HD is Maxtor 7Y250M0 (250GB,7200RPM, SATA, (C:NTFS) Used space: 16.8GB External HD is Maxtor 6Y080L0 USB Device (80GB, 7200RPM, Ultra-Ata (133) J: (FAT) Used space: 4.09 GB Should I convert the external drive to NTFS? If so, what will happen to my 4.09 GB of files that are on there ? (How do I do that ?) Also, is there any other points to watch out for ? Thank you for your answers.
