With "badblocks", which writes some patterns and re-reads it. But it's 
of course annoying slow. At these servers I was lucky. Both were "only" 
73GB disks used in a RAID-1, so only 2 small drives to check. With a 
RAID of 8x750GB disks, it will take a *long* time to check, if you 
cannot simply replace all disks at once. At this customer from today, I 
would have to take one drive, check it, replace it, let RAID rebuild 
CRC, take the next... a new mainboard is less work, so I try this 
first.
