Subtest￿02￿ODD￿

The￿ODD￿test￿runs￿on￿IDE￿CDROM/DVD-ROM￿&￿CD-RW.￿It￿will￿check￿the￿ODD￿driver’s￿functionality￿and￿performance.￿

1.￿ Controller￿Test￿

Check￿the￿CDROM￿controller’s￿status.￿

2.￿ Data￿Transfer￿Rate￿￿

Check￿the￿data￿transfer￿rate￿of￿the￿ODD￿drive.￿It￿will￿read￿data￿from￿the￿ODD￿disc￿ and￿calculate￿the￿data￿transfer￿rate.￿This￿test￿needs￿a￿data￿CD.￿￿

3.￿ Data￿CD￿Butterfly￿Seek￿

Check￿the￿seek￿function￿of￿the￿ODD￿drive.￿It￿will￿perform￿a￿serial￿of￿seeking￿ operations.￿First,￿locate￿the￿minimum￿LBA￿address,￿then￿the￿maximum,￿the￿sub- minimum,￿the￿sub-maximum￿and￿meet￿at￿center￿point.￿This￿test￿needs￿a￿data￿CD.￿

4.￿ Data￿CD￿Random￿Seek￿

Check￿the￿random￿seek￿function￿of￿ODD￿drive.￿Random￿access￿will￿reflect￿the￿ performance￿of￿the￿heads’￿random￿movement￿and￿seek.￿It￿tests￿for￿1000￿times.￿

5.￿ Data￿CD￿Sequence￿Seek￿

Check￿the￿sequential￿seek￿function￿of￿ODD￿drive.￿Perform￿location￿test￿to￿CD- RW￿under￿LBA￿mode￿with￿the￿location￿address￿increasing￿in￿sequence.￿

6.￿ Tray￿Eject￿Test￿

Check￿the￿eject￿function￿of￿the￿ODD.￿It￿will￿eject￿the￿ODD￿and￿ask￿the￿user￿to￿ confirm￿if￿the￿operation￿succeeds.
