When you attach two IDE ATA/ATAPI devices as master and subordinate IDE devices on a Windows XP-based computer, the following event may be logged in the System event log:
Event ID: 26 Source: Atapi Type: Warning Description: The driver has detected that device \device\IDEport0 has old or out-of-date firmware. Reduced performance may result.
This issue occurs because the Enable Operation command of Self-Monitoring Analysis and Reporting Technology (SMART) is not sent to the correct device. This command is always sent to the master device for each device.
