Run the Apple Hardware Test (AHT) from a external drive possible?

Hi my DVD drive is dead and i need to do a hardware test now but my macbook pro spits the dvds out., does anyone have experience with running AHT from external drive ?

What are you using AHT for specifically? Could you instead use a utility like Rember for checking RAM, which does a better job IMO than AHT?

i got it back from a authorized apple center that replaced the logic board and video card but now my dvd drive does not work and i can not test it with the original dvds, it was a recall on apples part for a faulty video card.
i want to test the v card as well as anything else i can do to see if someone snatched the original dvd drive becuase this thing was working before i took it there

How do I run the Apple Hardware Test? Its not on my DVD and the Internet-connected version tells me my computer isn't supported!

I have a mini - late 2010 2.4 ghz core 2 duo - that just started black-screen crashing and failing to wake from sleep. Up to a few dasy ago this was a really bulletproof machine! When trying to restart it afer a crash it sometimes emits three weak beeps (sometimes more).
Apart from spontaneous motherboard failure (??) I can only guess that the RAM failed (an 8GB upgrade installed last fall). I pulled one 4GB RAM board and the mini booted again! But it still sometimes fails to wake from sleep, and sometimes give the three beeps. I've run REMBER (a memory test program) on one of the RAM boards and it passes the test. My next step is to test the second one -- but whether it passes or fails there seems to be something else going on.
I'd love to try the Apple Hardware Test but:
- pressing D on startup has no effect (even when starting up with the original install DVD)
- pressing Option-D brings up an Internet-loading screen that brings up a Hardware Test screen then tells me my computer is not supported.
Is the AHT simply unavailable for my model of Mac? And/or is there any way to test my hardware?

The 2010 Mac Mini's came with a 2 DVD set, a Mac OS X Install DVD (22691-6657-A) and an Application DVD (22691-6658 -A). The Apple Hardware Test is on the Application DVD (22691-6658-A).

How long should the Apple Hardware Test (AHT) run?

II'm running the AHT on a 2012 quad core i5 iMac 16gb/3TB .....the progress bar moved quickly to about 7/8 done, about 4 minutes, but now has been sitting there for 40 minutes.
can anyone provide experience or input as to how long I should expect it to sit there?
thanks

If you run AHT in extended mode it can take over an hour to run, one factor is the HD capacity.

The error code 4MOT/4/4000003:HDD-1393 has shown up from the apple hardware test. What should I do about this?

My iMac has been running a little hot, it was suggested to run the Apple hardware test (AHT), as heat can cause problems witht he hard drive.
The AHT revealed the error code 4MOT/4/4000003:HDD-1393 which I assume means a hard dtrive problem. But, what do I do. Is this a critical error or a minor fault. Everything is running as normal, but the machine is getting a little hotter than usual.

This indicates problem with HD fan.
Exact nature of the problem is only known to Apple.
We have no way to interpret this error code.
Keep a backup of your data.
When you get a chance, take the Mac to the nearest Apple store to have it tested.
Best.

Apple Hardware Test AHT

Hi,
I would like to run the Apple Hardware Test (AHT) on my MacPro(2,1) and since I have upgraded from Panther through Leopard to Snow Leopard, I have misplaced the original installation disks that came with my Mac Pro. Is there anyway to run AHT without those original install disks? Is there somewhere to download the images that I need?
TIA .... Jon

You will have to call AppleCare and arrange to purchase replacements. There are no alternative sources for the AHT for your Mac Pro.

HT201257 Can I reinstall the Apple Hardware Test?

After an OS reinstall, with a Macintosh HD erase, I've lost the ability to run the Apple Hardware Test directly from my drive.
Now when I try to run it, it only does so from Internet Recovery Mode, which does not sit right by me, once it used to do so without requiring an internet connection and no official Apple article, specifically, warns you that any OS reinstall process can lead to this situation (at least none that I have discovered...)
Is there any way I can get back that feature, which I presume would be installed in a Recovery partition?

I was actually responding to your statement "I've lost the ability to run the Apple Hardware Test directly from my drive." and provided the link (see the Use Apple Hardware Test section) so that you can make sure you were performing the test correctly.
Sorry, that the Article was of no help to you.

I can"t open the apple hardware test from the applecare support website

i received the applecare training program for my birthday and while exploring the applecare service source website i found a image file of the apple hardware test (AHT) for each model along with a pdf of the service manual and a pdf of the AHT service codes. The problem i'm having is, i cant open the image of the AHT.

After downloading that image, open it and it will show up mounted in your desktop. Then, open Disk Utility (in /Applications/Utilities), right-click your Apple Hardware Test image in the sidebar and burn it to a DVD. Finally, start your computer from the disc, holding the C key, so Apple Hardware Test should start, always that you have the correct version for your computer.
You have Apple Hardware Test in the Applications disc that came with the computer. In that case, hold the D key while your computer is starting

Yet another pointless question about the practically non-existent iMac G5 Apple Hardware Test (AHT) disk.

I have a 17" iMac G5 (iSight model) also known as model A1144, PowerMac12,1 or MA063LL/A.
Where do I download the Apple Hardware Test (AHT) disk for this machine? Apparently nowhere. However, it would really help me on my quest if I knew what I was looking for.
Does anyone know what AHT version is compatable with my machine? 2.2.1? 2.3.1?
How about the part number on the disk? I have some Intel disks that say 2Z691-5734-A that (obviously) won't work.
Is the AHT on Disk 1 or Disk 2? I'm starting to think there never was an AHT for this model.
Where do I get those ASD disks the so called "geniuses" have?

Disk 1: 2Z691-53179-A
Disk 2: 2Z691-5493-A
Compatible with eMac (2005), iBook G4 (Late 2004), iBook G4 (Mid 2005), iMac G5 17-inch (ALS), iMac G5 20-inch (ALS), iMac G5 (17-inch iSight), iMac G5 (20-inch iSight), iMac (Early 2006 17-inch), iMac (Early 2006 20-inch), Mac mini, Mac mini (Late 2005), Mac mini (Early 2006), MacBook Pro, Power Mac G5 (Early 2005), Power Mac G5 (Late 2005), PowerBook G4 (15-inch Double-Layer SD), PowerBook G4 (17-inch Double-Layer SD)

AHT I think was on a seperate CD.
Thanks Kappy, if v2.2.1 then search for...
018-1680-A.dmg

Is there a download for the Apple Hardware test 3A126?

Is there a download for the Apple Hardware test 3A126? I get a gray screen for several minutes until start up, Tried holding down the "D" key but no test, there is a disc stuck in the superdrive so I can't use the install DVD.

You can only run the Apple Hardware Test from the correct Disc that came with your system. see > Intel-based Macs: Using Apple Hardware Test
Have you tried the following > The ultimate guide to ejecting a stuck disc
or > Eject a stuck disk from your Mac DVD super drive to get the stuck disc out?

G4 that will not boot from any disc EXCEPT the Apple Hardware Test CD

We have a DP 1ghz Quicksilver PowerMac G4 that will not boot from any disc EXCEPT the Apple Hardware Test CD that came with the machine.
We were in the process of installing 10.4 Tiger before placing it for sale.
The Mac was originally OSX Server 10.1 that we later converted to a worksation running 10.3 Panther.
It has 1 GB of memory, 80GB hardrive, 250MB Zip Drive and a Radeon 7500 video card.
Since this machine only has a CD-R drive and not a DVD-R, we installed Tiger using another Mac via Target Disk Mode. The installation process went well, but when I tried to reboot I got a Kernel Panic right after startup screen with the grey Apple logo.
On some reboots we get to the blue startup screen, others it stops at the grey Apple logo, others a black box like the a Kernel Panic - but with no text. Twice it went directly into Open Firmware.
We have done the following during our troubleshooting:
- Reseat RAM, Video Card, Hard Drive, Zip & CD-R connections
- Remove RAM 1 stick at a time and reboot
- Replace RAM with RAM from another working Quicksilver
- Replace Video Card with one from another working Quicksilver
- Zap PRAM
- Reset CUDA switch
- Unplug the MAC and remove everything (RAM, Battery, etc) for 30 minutes and try to reboot
- Tried booting from the Macintosh Server G4 Software Restore CD
- Tried booting from Mac OS X Server CD
- Tried booting from AppleCare Protection Plan CD with TechTool
- Tried booting from Diskwarrior CD
- Tried booting from an external FireWire drive with a disk image of Tiger OS Install
- Tried booting with the hard drive disconnected
The Mac WILL boot from the Apple Hardware Test CD and will pass ALL of the extended tests.

Conventional wisdom says that any Mac that will not boot up from a System/Install CD OS 9 or an Install CD Mac OS X, has a Hardware problem.
The diagnostic CD is a red herring because it uses a very primitive method of reading the CD, and so does not properly represent the machines general ability to read CDs.
I would look at the CD drive cables, etc, and see if another drive gives different results.
You have not mentioned using the Startup Manager (option key at Startup) to do any checking:

How can i get or download the apple hardware test for a macbook pro made in 2012 running Mavericks 10.9.3

Does anyone know how can i get or download the apple hardware test for a macbook pro made in 2012 running Mavericks 10.9.3. Thanks.

Sean and Andy -
I have to agree with Andy here. I am having the same problem on a mid 2010 MBP (6,2). I have already read the AHT info provided by Sean's link, and they are less than helpful. I'm sure they will be helpful to those who find that they work, but they are confusing if this is not the case. For example, my MBP(6,2) came with ONE (not two) installation disks, so the instructions don't work for me. Another issue is the instructions confound the descriptions related to the MBP, the original (delivered) software (OS X version), and the current installed OS X upgrade software.
So here's what does NOT work for me...
     (A) I cannot install 'Disk 2', since I never received this with my original (new) purchase in mid 2010.
     (B) I have checked my firmware versions and they are all up to date, as per Apple's information.
     (C) As suggested in another thread, I looked for /Library/Core Services/.diagnostics and it was NOT present. I followed his instructions, downloaded the correct (I believe) dmg, and installed it. It is in the correct place, and I can see all the invisible files using Pathfinder.
     (D) When I re-start holding down the D key (immediately), it just goes through the normal boot routine; no evidence of AHT.
     (E.1) When I re-start holding down OPT-D, I get a spinning globe, and then it prompts me for a network (wi-fi) connection.
     (E.2) For some unknown reason, the prompt identifies between 2 and 5 of my --neighbors'-- routers, but does not show mine. (??!!)
     (E.3) The routers are listed alphabetically; however, my router SHOULD be at the top of the list by this criterion, but it is nowhere to be seen.
     (E.4) The 'internet recovery' process then allows me to enter a network name AND password. I do this, for my current wi-fi router, and the process rejects it as an incorrect login ID. It is NOT an incorrect login ID!
So, now asking Sean and Andy (or anyone else) for further suggestions... ??? As Andy suggested, many people ask questions here because they have -already- worked through the 'official' recommendations, and have found them to be inadequate.
Any advice would be appreciated! TIA.

Apple Hardware Test (AHT) Hard Drive Full Read Fail But SMART Status OK

I have a Mac mini Server from Mid 2010 running Snow Leopard Server.
Ocassionally, it'll freeze up with the spinning beachball wheel for a few minutes. This usually happens when opening an app or performing an app function from the menu bar. It's a pretty clean system—there are not many apps installed.
I suspect it's a hadrware issue. I ran Disk Utility's Permission and Disk Repair. All good. SMART Status is verified. So I ran the Apple Hardware Test. Everything passes except for the Hard Drive's "Full Read"—it fails because "Reading took longer than the average time". The Hard Drive "Short .. test" and "Check SMART Status" pass.
Does anyone have an idea of what's going on here? Is the hard drive the issue? I don't understand how there can be a read issue (or hard drive issue), when the SMART Status is verfied.

S.M.A.R.T isn't perfect. Neither is AHT for that matter, but if it is reporting that reading is taking longer than it should then an impending failure is likely. The occasional "wait cursor" appearance supports that diagnosis.
Consider yourself fortunate in that you still have the ability to back up anything important, and you can plan a convenient time for its replacement.

Apple Hardware Test (AHT), buzzing noise, fan blows loud, & AHT crashes

Hi there,
I've finally had it with some hardware issues that I've had since day 1 of owning this G5 Dual 1.8.
Running10.4.9 OSX...
Nothing that has affected my day to day working-yet, but growing problems, fans get loud, awful buzzing noise from inside the tower comes and goes and grows in volume when it's happening. I believe it's coming from the internal drive bays... Both of which are filled with 2 new SATA Seagate internals that don't appear to be slowing up or spinning a processing error when I'm working...
When I run an Apple Hardware Test, The AHT disc crashes each time at the 5 minute and :12 second mark while "In Progress" on the "Mass Storage" test, it freezes and the fan gets loud. I do a hard restart to get up and running ok each time afterwards.
I've never received a complete AHT result of tests summary, ever, so I don't know what's really wrong, ever. But I know something is not right. Using Disk Utility is a joke, SMART status is always "verified" of course, no obvious system software errors.
I'm using the disc that came with my G5 "Additional Software Apple Hardware Test":
AHT Version 2.2.2
Disc Version: 1.1
I've scoured Apple knowledge base for anything on this version-but nothing.
Any suggestions please. IS there any hardware testing software out there besides the faulty AHT disc software Apple provides? The nearest Apple store is over an hour and half away, I just don't have time to drive there to hear the same thing I already know, and if I could pinpoint the problem myself with proper software, I can handle doing the maintenance....
Please help!
Thanks!
DAve

Some G5s had a firmware update that caused problems with the version of Apple Hardware Test that shipped with the G5. The Latest G5 Apple Hardware Test is 2.2.5
Call Apple and see if you can get it.
Another hardware test is TechTool Pro

Meanwhile, try testing with some of the RAM removed. Try different combinations of RAM modules and slots. Always use them in pairs.

Cannot start-up to the Apple Hardware Test — MacBook Pro & Lion

Whenever I try holding the D key before and throughout all of the start-up process, it simply makes the grey screen appear for longer, and slow the whole process... but never beings the Apple Hardware Test.
I'm following Apple's official instructions:
To start up your computer in Apple Hardware Test:
Press the power button to turn on your computer.
Press and hold the D key before the gray startup screen appears. An Internet-enabled connection via Ethernet or Wi-Fi is required to use this feature.
Note: Some Macintosh computers that shipped with OS X Lion support the use of Apple Hardware Test over the Internet. These computers will start up to an Internet-based version of AHT if the hard drive does not contain AHT.
Why doesn't it work?
My MBP was shipped as follows:
For Apple computers that shipped with Mac OS X v10.5.5 to 10.6.7, Apple Hardware Test is located on the Applications Install Disc 2 and should be included with your computer.
But I have upgraded to Lion! Do I need the disk still? If so, why am I to lumber around a disk from a previous OS... good that I didn't throw it out!

I'm trying to find the answer to a similiar question. Here's my thread.
