RAID problem

[Quintilo]

Hello

Some weeks ago I installed Windows Vista on my MSI neo2 P35 motherboard, with two harddisk of 320 gig each, in RAID 0. So in fact it can be considered as being one big hd. Windows is on the ntfs-partition, i also made a fat32 partition and free space for linux.

Then i installed linux fedora 7 one the empty part of the ""harddisk"". Untill yesterday i was not aware of any problem. But now i want to mount my fat32 partition in linux. So i used fdisk to inspect the partitions in a terminal. But when i inspect 'sda' it says it is 320 gig big and there is some partition information. When i inspect 'sdb' it also says it is 320 gig big, without partition information.

When i try to mount the fat32 partition i get an error. I think the problem may be that linux has problems with the raid 0 configuration. To me it is very strange that linux detects that i have to disks of 320 gig, i thought linux could not now that, shouldn't linux only see a big harddrive of about 640 gig?

hope someone can tell me how i can resolve this issue, in particular the mounting problem.

Linux seems to have problems with fat-32 and ntfs but nfat and vfat work also using a quick transfer to an extra drive would allow you to reformat everything to ext3 along with support files could allow windows to still operate whilst both are on the same partition the only thing is that since Linux acts as bridged within the motherboard I'd suspect that you may still See two drives, But someone told me that you can merge the two and get them to display properly using a merger application in Linux though I don't know of one of hand.

I've never had a problem w/ fat32 from Linux. Post the result of "fdisk -l" from Linux,
and also the result of "df"

Something is clearly wrong. Linux can use a bios raid0, no problem.
Ovbiosly Linux is NOT installed on an unpartitioned disk, so /dev/sda
and /dev/sdb are not the right names I think.

Is it a built-in hardware RAID controller on the motherboard?
The todays built-in "hardware" raid controllers are not exactly hardware ones. They are just ordinary sata cards with *software* raid. And this combination only works properly on *windoze*.

But real hardware RAID controller (costs more than 200$) however works perfect on both linux and windoze.

in all the years I have been using linux (right from RH5.2) ... i have never had a problem with linux and vfat (fat32) ntfs in later distros. but what is nfat?

seems to me if linux sees two separate hard disks, then clearly the raid configuration is not recognised. its prolly a windoze raid setup.
