I reformatted it using EASEUS patition master 9. also, when I did boot from disc (the xp install disc) and chose which partition to use, I also formatted it again for good measure, both times in NTFS.
Yes, explorer.exe. I went into the windows system folder and chose to open it with explorer.exe. The weird thing is the box for "always open with this program" is greyed out, no matter what program I choose.
As double clicking leads to the pop up about not knowing how to open it, I can simply right click and choose "explore" and it will open as it normally should, with some folders that have been there sitting there like I expect. I have no problem accessing, adding, or deleting the data on that partition.
I am not at that computer at the moment, but I will update with the last 2 requests soon.
