Also, because the new HDD is 160GB, it is too big to be formatted to a FAT32 file system. So I had no option but to format it to NTFS.
So...... to be compatible, I have to convert the original master HDD, Samsung 36GB, which is C drive, from FAT32 to NTFS.
Can I convert C drive from FAT32 to NTFS without backing up everything on the drive?
