afmonter de 2 diske i raid , hvis de er "mirrored" burde de jo være ens
hvis du ikke har slettet for meget.

brug evt. sysrescd eller anden live/boot CD for at rode, jeg kan
heller ikke se

start med at lave fuld sektor backup af begge diske/partitioner (selvom det fylder),
så kan du gå tilbage hvis du kommer til at lave noget mere forkert.


jeg  antager det var software raid i linux du anvendte , ikke
en avanceret hardware-raid controller.

svaret i den tråd er vist at du nok har tabt det meste indhold.

De firmaer du henviser til er mest ved hardware fejl.
software fejl kan man bruge diverse værktøjer, men desværre
findes de kun til  windows.

I linux kan man prøve en fsck.ext3 på partitionerne, men lav
som ovenfor nævnt først en sektor-backup!
tabte filer kan så måske findes i lost+found/, men
måske kun med nodenr som navn, ikke det oprindelige navn.
(det afhænger lidt af hvad der er fundet)
