Abstract: Systems and methods are provided for performing diagnostics on a removable media drive. An example system includes a monitoring unit configured to collect information about a media access to the media drive and a media access to a removable media contained in the media drive. The example system also includes a storage unit having a threshold table with at least one threshold value for the media access to the media drive. A processing unit is configured to compare the collected information of the monitoring unit to the at least one threshold value contained in the threshold table. The processing unit is also configured to determine diagnostic data relating to the removable media drive in accordance with the comparison.

Abstract: Disturbance detection is used to detect anomalies in the behaviour of the data signal. The data signal may for example be a readout signal in an optical drive. An upper and a lower envelope signal value for the data signal are determined in a determined time interval (&Dgr;(m−1)). During the following time interval (&Dgr;(m)) a difference value is computed by subtracting from each other the values of the lower from the upper envelope signals. A disturbance is detected in case the difference value is smaller than a predetermined border value.
