It surely is.  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.

All the best,
Stefan Hübner
