| 1. A method, comprising:
tuning error recovery in a storage device by:
receiving a user command to set an error recovery level of the storage device;
propagating the user command down the layers of the input/output stack;
as the user command is propagated, selectively modifying the user command;
when the command indicates one state, enabling limited error recovery for failed input/output operations; and
when the command indicates another state, enabling a higher level of error recovery for failed input/output operations.
