1. An apparatus for recording and interpreting the interface signals on the Advanced Technology Attachment (ATA) interface or Integrated Drive Electronics (IDE) interface or substantially similar interface comprising:

  • (a) a recording means for recording said interface signals;

    (b) an interpreting means for interpreting said interface signals into their higher level categories of event type, register or address, and data value;

    (c) a communicating means for communicating information between said apparatus and a computer or human user;

    (d) a trigger comparison means for generating a trigger signal when said interface signals match a predetermined trigger pattern;

    (e) a control circuit for starting/stopping said recording means relative to said trigger signal;

    (f) a trigger selection means for user selection of the trigger pattern in said categories of event type, register or address, and data value, and translating the user selection into said trigger pattern to be used by said trigger comparison means, whereby a user may select a valid trigger pattern without a knowledge of the function of each of said interface signals;

    (g) a trigger mask means for masking portions of said interface signals from said trigger comparison means, whereby interface signals or certain of said categories or options within said categories may be ignored.
