Description Mateusz Albecki 2020-10-26 08:54:01 UTC 
When in AHCI mode AtaAtapiPassThru driver should recover any errors the port might signal. Error recovery procedure is covered by AHCI spec in section 6.2.2 of the AHCI spec 1.3.1.

It is possible to encounter a fata SATA port error during the boot and in such case it is possible that drive will become unresponsive and needs a SW assistance to make it work again. If we do not recover the port all subsequent commands to the port will fail.
