I have;
-tried booting, the computer hangs after bios, and after initialising the raidcontroller.
- booted mandriva linux 2011 from dvd, and ran diskdrake, its main hdd utility. Upon starting tis it told me that the partitions on sda and sdb were too currupted, and could not be restored.

I have not tried fsck, as the drives arent recognised as beeing partitioned. I have used "dmraid -a y" command, but that didnt work either.
And im affraid i cannot use datarecovery tools as the data is stripped over two disks and they cannot be seen as one as long as raid isnt working.
So judging from here i guess the datas is lost than..
Or could running fsck still work?

Its a win7 system, i guess using ntfs.
