Test Estimated completion time Description

Short Random Multi-block 2 minutes Performs a threaded, random

multi-block read of random

ranges of the target hard drive.

This is not a full surface scan,

but it will cause rapid seeking

and reading of hard drive

blocks. If a block can’t be read,

an error occurs.

This test is available for hard

drives, not solid-state drives.

SSD Threaded Media Scan Not available Scan’s the entire accessible area

of a solid-state drive.

This test is available for solid-

state drives, not hard drives.

SSD New Drive SMART Data Not available Checks the SMART status of a

solid-state drive.

This test is available for solid-

state drives, not hard drives.

Memory Tests

All memory tests are categorized here.

Simple Memory Tests

AXD Mac OS X memory tests test the rst 2.5 GB of memory. All multicore memory

tests listed in AXD EFI tools are run.

Even though these tests don’t test all memory, run these tests to detect intermittent

memory issues.

After the rst 2.5 GB of memory is tested, the memory test then tests for ECC errors.

When an ECC error occurs, memory catches the problem and xes it. The test detects

the number of memory xes and reports them.

Note: The time required to complete memory tests correlates to the size of memory

being tested. These estimates are based on testing 1 GB of memory.

Test Estimated completion time Description

Simple Test 12 minutes Runs all multicore memory tests

listed in AXD EFI tools, reports

the number of ECC errors, and

then resets the count.
