Since you're to the point of reformatting and not worrying about data loss... having a raw disk isn't so bad... The thought of you having your root drive as NTFS and your slave as FAT32 might be an issue.. but I'm not sure about that... you can always goto Disk management and repartition and format the disk as it should be... One thing to remember is that once you format a disk NTFS, it doesn't like to be reverted back to FAT. If I were you, I'd just make them both NTFS. If you have trouble getting the partitioning or formatting to work.. try downloading the demo version of Partition Doctor Pro.
