Optical Butterfly Seek Test Failure Information

Group 6202

Device Optical

This group provides tests optical media devices. Optical device that can be tested are CD-ROM, DVD or Blu-ray drives. There are tests to cover both the mechanical and data read capabilities of the drives from the pre-boot environment. If required, data write tests are available in the Windows diagnostics suite.

Note: Requires suitable data disc media appropriate to the drive type and operating mode to be tested (CD, DVD or Blu-ray).

Note: 'ROM' Data Only Media must be used and ideally of near total capacity to ensure full travel of the device head during tests.

Test Number 403

Test Name Butterfly Seek

Each Butterfly Seek test iteration consists of two seeks: one seek is lower than (below) the middle sector and one seek is higher than (above) the middle sector. After each iteration, the lower seek position increases and the higher seek position decreases by the same amount.

PARAM1: Duration

Time to run the test for in seconds.

PARAM2: Coverage

Percentage coverage.

PARAM3: Maximum Errors

Continues to test until the maximum number of errors is reached, only errors directly associated with reading the drive.
