Looking at the Wikipedia article about Error Recovery Control, it mentions[1] the FreeBSD handles this better.
Just what do they do and could it be done in Debian? Or is somebody already working on something like this for the kernel? "In a software RAID configuration whether or not TLER is helpful is dependent on the operating system. For example, in FreeBSD the ATA/CAM stack controls the timeouts, and is set to progressively increase the timeouts as they occur. Thus, if a desktop disk without TLER starts delaying a response to a sector read, FreeBSD will retry the read with successively longer timeouts to prevent prematurely dropping the disk out of the array." 1. https://en.wikipedia.org/wiki/Error_recovery_control#Standalone_vs._RAID_considerations
