My friend has a system with dual boot: Windwos XP Home, Windows 98. His hard drive (one only in the system) is partitioned into many partitions:
C: Win98 - installed with Windows 98 (FAT32)
D: App98 - installed applications under Win98 (FAT32)
E: 98Data1 - data files for Win98 (FAT32)
F: 98Data2 - data files for Win98 (FAT32)
G: WinXP - installed with Windows XP Home (NTFS)
H: AppXP - installed applications under WinXP (NTFS)
K: XPData - data files for WinXP (NTFS)

He boots in WinXP. If he deleted (just press DEL key) a file from E, he can't find it in the Recycle Bin. I tried that and even dragged the file into the Recycle Bin on the desktop. The file disappear in E drive but not shown in the Recycle Bin.

However, I did the same for files in F:, I can see the files shown in the Recycle Bin.

If anyone has any clue on this strange situation, please advice me, thanks.
