How to check RAID1 parity

Hi.

I have 2 500 GB harddisks as RAID1 in my XPS700. Normally, the nVIDIA RAID controller only reports errors when the files are accessed. Can I tell the nVIDIA RAID controller to make a check of the data integrity, i.e. make it compare the complete content of both disks?

Usually, hardware RAID controllers offer a funktion called "parity check", which checks the complete RAID array for errors. I case there's a problem, the faulty disk can be replaced.

Is that also somehow possible with the nVIDIA RAID controller?

Thanks,
