Swapping with grub prevents accessing FAT32 dos drive

[Burzek]

Hi,

Here is the list of my hdd and partition configs.

Primary Master HDD:
Total 20 gigs: has 2 partitions both Fat32
-   8 gb FAT32 is drive c:
- 12 gb FAT32 is drive e:

Primary Slave HDD:
Total 20 gigs: has 1 Fat32 partition  is drive d:

I installed Mandrake 8.1 as partitionless to Primary Master HDD to 8gig 
partition.
Grub is in charge of boot loading now.
I got my windows 98 in the Primary Slave HDD.

The problem is , when I boot and swap the harddrives with
map (hd0) (hd1)
map (hd1) (hd0)
I can see and access both drives;
drive C: that is hd0,0 and drive D: that is hd1,0.

However, even I see the drive letter "E" from dos programmes, I can
not access to drive E: that is hd0,1

It is a 12gb  FAT32 partition, dos Fdisk sees the drive logically as
e: but reports the logical drive filesystem as unknown.
THIS PROBLEM ONLY happens when drives are swapped with map method.
When I boot win98 via GRUB without swapping drives, I can access to my
drive e:

I tried to use the -unhide option and lots of stuff, but as a newbie could not
do anything.
One more thing when I get the geometry, the GRUB shows the partition
as hd0,4.
However, when I try to unhide hd0,4 , it says there is no such
partition...

Please help, what commands should I use to access my Fat32 partition?

Thanks...
