4.6.2 HDD
 DiskBadBlksTest (SP): Searches for bad blocks on a device (usually a disk partition).
 DiskCntlrTest (SP & PP): Verifies the random data written to disks remains unchanged. It
verifies only IDE and SCSI controllers that are associated with mounted file systems. Disk
controllers associated with read-only mounted file systems are not verified.
4.6.3 Memory
 MemCntlrTest (SP & PP): Randomly writes to areas of memory, then reads the memory
back to ensure the written values remain unchanged.
 RandomMemoryTest (SP & PP): Performs stress testing on the memory subsystem. This
test is effective in finding intermittent and non-deterministic faults. The problems in other
hardware areas such as overheating CPU, out-of-specification power supply, and so on can
cause memory faults.
 MemBandwidth: Measures the ability to copy, read, and writer data over a varying set of
sizes.
 MemLatency: Measures the time taken by the memory to respond with the data for read-
request.
4.6.4 OS
 MemSepTest (SP & PP): Ensures that user space programs cannot read and write to areas
of memory utilized by items such as Video RAM and kernel code.
 SupervisorInstrTest (SP): Ensures that the enforcement of the property that privileged
instructions should only be in supervisor mode is still in effect. The set of privileged
instructions tested to confirm this is architecture dependent.
 DmesgCheckTest (SP & PP): Checks for user given keywords in the kernel dmesg logs.
