Re: Partition Number Ambiguity
You can only have 4 primary partitions on a hard disk. To use more than that, msdos/windows fdisk create an extended partition when then gets carved up into smaller partitions.
When you installed windows, it made your primary NTFS in the first available primary partition slot (which linux sees as hda1). When the Fat32 drive was created, dos/windows makes an extended partition by default which covers the rest of your hard disk, and takes part of it as the fat32 (linux sees this as hda5), the next partitions then are created as hda6 hda7 hda8 and so on.
Hope that helps :-)
