ATA driver gives absolutely no clue about the reason of the failure and just disconnects device. I'm curious why the driver behaves in this way. If SATA code is just raw, it definitely must be corrected to implement proper error recovery. If SATA specification is written so purely that proper error recovery is just impossible (I really doubt if it's so), then SATA hardware should be simply avoided in mission-critical applications.
