Abstract
Technologies are described herein for or enhancing error recovery procedures in a storage device by utilizing on-the-fly error type detection. After a read error has occurred, a number of read retries are performed through an adaptive read channel in the storage device. The current channel parameters of the adaptive read channel are then compared to a number of predetermined channel parameter sets, each associated with an error type, to determine the most probable type of error that occurred. Finally, an error recovery sequence is selected to recover from the read error based on the determined error type.
