via sata problem

[memorex]

I have 2 sata drives.

the mobo is MSI PT880 Neo.

All worked fine, but today i decided to re-install windows.

I did it with norton ghost, but it screwed up my drives.

Even my ide drive is unreadable!.

So I decided to do a fresh install.

when the raid bios is on, sometimes it recognizes 1 drive,

but when i continue with XP install and press F6 for loading the

VIA driver from floppy, it ends with NO drives !!!.

sometimes it the pc recognizes NO sata drive.

is there a way to test that the sata drives are connected the right way ?.

If the mbr and so is screwed up, is there a way to renew that ?.

And at last: the driver which is loaded after F6, where is it put and how can

I manually delete that ?.
