Abstract
A peripheral device (which is preferably a disk drive) can automatically collect trace data upon detecting certain error conditions. The peripheral device has the ability to selectively alter the range of state data collected in a trace depending on the error type. Preferably, the device includes a programmable processor executing a control program. A set of trace switches, each enabling a corresponding set of trace points, can be independently set by the control program. An error trace identification table identifies, for each error type, a corresponding set of trace switches. If an error is encountered, the trace switches corresponding to the error type are determined from the table, and the switches are set accordingly. In another invention aspect, a set of trap switches in the device can be set to trap on the occurrence of a specific error type, thereby supporting a more detailed error analysis.
