Most "real" HDD manufacturers have an advance replacement policy for their customers' convenience. Why doesn't IBM? It is ludicrous to make me buy another drive to temporarily store any data I can recover, ship the old drive off, and wait 2 weeks to get a new one to transfer my data back, when I can just have a new one in my hands in 3 days, dd if=/dev/hda of=/dev/hdb, and send the duff drive off in the same packaging the replacement arrived in.
