There are many more than 4 cases in a month, one could earn a living from it - thank you very much harddisk producers. What we need: setting Error Recovery Control timeouts upon assembly of RAIDs on ATA-disks. Then the normal disks behave like the raid-edition disks from some vendors (i.e. Hitachi even documents on it for the 7K2000 Deskstar drives - well, only between the lines). But this feature is pretty hard to implement - you'll have to guess and test if a disk understands ATA.
