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 ra te. 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 cen ter 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 moveme nt and seek. It tests for 1000 times. 
5. Data CD Sequence Seek 
Check the sequential seek function of OD D drive. Perform location test to CD-
RW under LBA mode with the locati on 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.
