I am new to Ext hard drives and just purchased a WD 250 GB portable drive which uses FAT32. I am not too familiar with the differences between FAT32 and NTFS but I think that I remember reading where NTFS is better. I am going to use this to backup 20GB of photos, music and maybe 10 GB of documents. Do I need to convert to NTFS? What are the differences/advantages of the two. Thank you in advance!
