Nucleus Name
DS_HDD_LinearSurfaceScan
Nucleus Number
2109
Description
Perform a linear surface scan so that most of the disc is covered.
Technical
-
Initialise the HDD connection
-
Get the user input
-
Generate a sequence of test sectors according to the user input
-
For every sector in the sequence do
-
Read the sector and measure the time to perform this action
-
Update a list of statistics about the measurement
-
Display statistical information about the test sequence
-
If more than 1% above 100 ms and/or more than 0.1% above 200 msec and/
or requests above 300 msec make the result of the test fail.
Execution Time
Depending on the user input x times 30 seconds
User Input
parameters in the next format:
<SECTORS> <STEP> <LOW> <HIGH> <GRAPH>
- SECTORS: Specifies the number of sectors to read in each access
- STEP: Specifies the step (in sectors) between each access.
- LOW: The start sector address of an explicit range of LBA addresses to be used
for testing. If no value is entered LBA 0 will be used
- HIGH: The end sector address of an explicit range of LBA addresses to be used for
testing. If no value is entered the maximum LBA will be used.
- "GRAPH" optional to print out the measured read scan graph
