9.0 Deviations from standard The device conforms to the referenced specifications with deviations described below. The interface conforms to the Working Document of Information Technology, AT Attachment with Packet Interface Extension (ATA/ATAPI-5), Revision 3 dated February 29, 2000, with deviation as follows: Standby Timer Standby timer is enabled by STANDBY command or IDLE command. The value in the Sector Count register shall be used to determine the time programmed into the Standby timer. If the Sector Count register is zero, then the Standby timer is set to 109 minutes automatically. Write Verify WRITE VERIFY command does not include read verification after write operation. The function is the same as WRITE SECTORS command. S.M.A.R.T. Return Status S.M.A.R.T. RETURN STATUS subcommand does not check advisory attributes. This means that the device will not report a threshold exceeded condition unless the prefailure attributes exceed their corresponding thresholds. For example, a Power-On Hours Attribute never results in a negative reliability status. Travelstar 48GH, 30GN & 15GN hard disk drive specifications 69
