System Block Device Random Read Test Failure Information

Group 7702

Device System Block Device

Provides testing for block based system storage that has only limited BIOS support during the pre-boot phase. Typically this will be embedded flash memory that does not connect via a traditional disk bus such as SATA, SCSI or USB. A typical examples might be eMMC in systems with a mobile form factor.

Test Number 402

Test Name Random Read

Exercises a drive's read capability using pseudo-random read addresses (these are randomly generated using a fixed computational process). A quick benchmark is performed on the device to determine a read rate. Success or failure of each read is monitored.

PARAM1: Duration

Time to run the test for in seconds.

PARAM3: Maximum Errors

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

ERRORCODES & TROUBLESHOOTING

The test cannot be executed because something is not supported. CODE="0x00/3FF"
TROUBLESHOOTING1: A program error, such as a memory allocation failure. Check for BIOS updates. The test was inconclusive.

Device_ID VALUE unknown (Exceeds array depth). CODE="0x01/3FF"
TROUBLESHOOTING1: A program error, such as a memory allocation failure. Check for BIOS updates. The test was inconclusive.

Device is too small to test. CODE="0x02/3FF"
TROUBLESHOOTING0: The device appears to be faulty.

Device read failed. CODE="0x03/3FF"
TROUBLESHOOTING0: The device appears to be faulty.
