I see. It seems the way the driver Areca offers on its download page does this is wrong, then, as all I did was I ported the feature from there. > But this really needs an explanation on why you'd need a configurable > timeout to start with. A colleague of mine has experienced problems with disks not supporting TLER performing lengthy error recovery, hitting a timeout. He has mitigated this problem by configuring the timeout to be long enough to allow for the error recovery to finish. And again, the driver offered by Areca supports this feature, so it seems they have their reasons as well.
