No, it isn't an issue of the file system drive formatting NTFS, Fat 32 etc. . It is the partition type. Drive management. Partition as GPT, Not MBR as MBR has a limit of 2 TBS. and ya can use any drive size as a storage drive with 7. Use NTFS as that is Windows. The sector size isn't important. Not the same as a systems,(C), drive. Ya can't use GPT easily for a systems drive with 7. Not really that confusing.
That was easy.
