Apple Hardware Test: HDD

Hello there,
I own an iMac 27" (late-2009).
A few days ago, when I pressed the power button (voilà), it returned my a kernel panic gray-screen, with ACPI driver error log.
Just tried to (archive) install the OS X (Snow) again but no success. Then, formatted and seems to workin' good.
2 days later, same error... But Archive+Install worked fine.
Today I've fired the Apple Hardware Test and it showed the following error:
4MOT/4/40000003: HDD-1278
I've done my insanely Google search, but no success.
Does anyone knows what means this error? May I have to change the Hard Drive Disk ?
Thanks so much,
-D

For the 27: Optical drive 998 rpm, hard drive 1100 rpm and CPU fan 938 rpm
There are some temps reflecting computers mostly at idle in this thread. They could go somewhat higher.

Unless you see some really wacky HD fan speed, can't really tell whether it's the drive or the HD fan. Needs to be diagnosed by Apple or some tech.

What are the meanings of Apple Hardware Test error codes 4m0t/4/40000003:hdd-1300 and 4m0t/4/40000003:hdd-1308?

what are the meanings of Apple Hardware Test error codes 4m0t/4/40000003:hdd-1300 and 4m0t/4/40000003:hdd-1308?

Thanks - Even though I'm years out of warranty I got chat help from Apple (I said they should help me since the codes aren't published.) We covered three different questions, and although I didn't get a specific decoding of the error code, I got confirmation of what other comments here imply - it might have helped that I indicated I'd already been here - and useful links to how to do back ups, including to CD(s). (I don't have a lot of data on this computer yet)
Now I need to figure out how to decide how hot-to-the-touch is "too hot" for the metal frame at the top of the iMac to decide whether I'm getting adequate fan performance or insufficient. While chatting I initially reported it was cool at the bottom and warm at the top. Apple hadn't asked, but their response prompted me to feel it again, and I'd say the top was hot, not warm - I updated but Apple didn't comment further except to conclude after addressing the other questions that I should take it in for further assessment - don't really want to bother with that.

Apple Hardware Test on a late 2008 MBP new HDD

Hey Community!
I own a Mac Book Pro - Late 2008 shipped with OSX 10.5.5. Currently I a new 500GB HDD and a 265 SDD are running in my MBP. The Super Drive is in an external USB Housing. Current OS X is version 10.7.1.
I need to run the Apple Hardware Test, because sometimes the system seems to freeze for at least 30 seconds.
What I've already tried:
*) Holding down "D" at the startup -> nothing happens, normal startup
*) setting start volume to external fire wire optical drive, insert 10.5.5. Installation disc, restart, holding down "D" -> startup with installation wizard
*) same with 10.6 Installation disc
*) same with choosing the Backup Partition when holding down "Alt" at startup and then pressing "D"
Always, I was connected via WIFI and Ethernet.
Can someone give me an advise how to run the Apple Hardware Test, or how to reinstall it on the new SDD Harddrive, where my system is mounted?
Thank u and greetings from Austria
Claudio

Try using your disk utility to read the drives. I'm not at my computer now but if you go into utilities->disk utility you might be able to solve it from there.
Also try holding down the C key on boot or esc.

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.

HT4543 Hi guys, I got this error code when I did my apple hardware test. 4MOT/2/40000004:HDD-1379 does anyone have an idea of what this could mean? Please Help .

You can buy and install the hard drive you want to. However, on Late 2009 and newer iMacs the temperature sensor is in the hard drive, so if you replace it with a hard drive that has not got a temperature sensor you will have serious fan problems.
You have got an Early 2009 iMac, so do not worry about this. You can buy a hard drive at OWC > http://eshop.macsales.com/shop/hard-drives/3.5-SerialATA/ Follow these steps > http://www.ifixit.com/Guide/iMac+Intel+24-Inch+EMC+2267+Hard+Drive+Replacement/9 028

2008 iMac running beautifully untill recently. Screen glitches and freezing. Apple Hardware test showed error code 4MOT/2/40000004:ADD and I have not seen others with this code. Guessing it is a fan issue based on the ODD and HDD error codes

computer felt hot and while running apple hardware test the screen glitches covered the screen and it froze. Now computer wont boot up. Again AHT code is 4MOT/2/40000004:ADD and I have just seen ODD and HDD codes discussed on other threads.Those were hardrive or superdrive fans, so I am guessing this is a fan issue and then it fried by graphics card. Any help as to whether this is game over or worth repairing would be very appreciated.

You need to take it to your local Apple Store or AASP for a professional evaluation. Apple does not publish the codes from AHT, you can Google the code you got and see if you can determine what it means however the best method is to let a pro handle it.

Files/Folders Sticking to Mouse Pointer - Not Releasing (Reset PRAM & Apple Hardware Test Fail to Run)

I've been having two issues with my Late 2008 MacBook Pro 15-inch - Running OS X 10.8.5 (Mountain Lion). Unable to Reset the PRAM and Run Apple Hardware Test (AHT).
On a random basis - File/Folder icons are Sticking to the Mouse Pointer - Not Releasing. I've done everything from trashing finder preferences, making sure Universal Access preferences are off, Restoring Defaults in the Energy Saver System Preferences, Resetting the System SMC. Another post mentioned that this is being caused by the Graphics Driver not working correctly - and mentioned to put the MBP to sleep, then wake it up, and the files/folders are no longer sticking to the mouse pointer. This works for me and released the sticking items in the Finder.
OK, Good this is a simple fix, BUT, what is really causing this issue, and how may it be fixed or repaired?
I also tried to Reset the PRAM and Run the Apple Hardware test (AHT), and these both fail to run on my MacBook Pro with OS X 10.8.5.
1) Resetting the PRAM:
Shut down the MBP, press the power button, and hold down at the same time <option><command>-P-R. The Reset PRAM process never starts up, but rather I receive the Padlock/Password Login which logs me into the Restore System Utilities. I'm unable to Reset the PRAM.
2) Apple Hardware Test (AHT):
Shut down the MBP, press the power button, and hold down the "D" key, the system boots up as normal and does not enter the AHT.
The File/Folder Finder sticking to the mouse pointer issue is very annoying. Does anyone have a solution to resolve this issue?
- Cheers

HI Barbara,
It sounds like the hard drive is failing or has failed. Boot from your Mac install disc and if you can run Disk Utility in case the startup disk needs repairs.
Insert your install disk and Restart, holding down the "C" key until grey Apple appears.
Go to Installer menu and launch Disk Utility.
Select your HDD (manufacturer ID) in the left panel.
Select First Aid in the Main panel.
*(Check S.M.A.R.T Status of HDD at the bottom of right panel. It should say: Verified)*
Click Repair Disk on the bottom right.
If DU reports disk does not need repairs quit DU and restart.
If DU reports errors Repair again and again until DU reports disk is repaired.
When you are finished with DU, from the Menu Bar, select Utilities/Startup Manager.
Select your start up disk and click Restart
While you have the Disk Utility window open, look at the bottom of the window. Where you see Capacity and Available. *Make sure there is always 10% to 15% free disk space*
If you cannot boot from your install disc, try booting in Safe Mode
What is Safe Mode

Built-In Apple Hardware Test

From my understanding, all new Macs have Apple Hardware Test built in directly to the EFI. Does this also apply to the Mid-2009 MacBook? I tried holding 'D' on startup but just ended up with a white screen. Is there a different keystroke?

How to run hardware diagnostics for an Intel Mac
Boot from your original OS X Installer Disc One that came with your computer. After the chime press and hold down the "D" key until the diagnostic screen appears. Run the extended tests for a minimum of two or three hours. If any error messages appear note them down as you will need to report them to the service tech when you take the computer in for repair.
Some "common" error indicators:
SNS - sensor error
MEM - memory error
HDD - hard disk drive error
MOT - fan error

Apple Hardware Test won't start from original Apple DVD

I'll make this one short and to the point, and here're what I did to try to start the Apple Hardware Test - and failed:
1) Disconnected all connected network and hardware except the bare essentials (Apple USB keyboard and mouse).
2) Insert DVD#1 of the original iMac media (then OS X v10.5.2)
3) Shut off iMac. Start, holding 'D' key (with the iMac DVD#1 in the drive)
4) Keep holding 'D' key, AHT didn't start, instead the DVD disc ejects, and the grey screen shows folder with question mark, nothing happens thereafter.
5) Repeated 10x, no difference.
Somebody knows what's wrong?

Holding down C key does start the Mac OS X installer; in which I was able to "partially" diagnose that my HDD is toast by using the Disk Utility. It formats (erases), but as soon as I finished erasing, I tried to verify the disk, and it says it already has problems and cannot be repaired.
I am thinking if during the loading of AHT (from DVD), it tries to cache some files onto the internal hard drive. Since my drive is no good - thus the reason for my using AHT, which is to find out if I get a 4HDD/11 type error - the AHT simply cannot load under my circumstances.

Graphics card/logic board issues: Macbook Pro Freezing during Apple Hardware Test!

I have a macbook pro that was working fine then the screen started acting funny. It would sometimes "tile" up where you would see the same issue repeated over and over on the screen and then computer would freeze. Sometimes the screen would start to have a strobing look and then freeze. I thought the computer was crashing but once the screen froze but the processor was still running. I knew the computer was still processing because I was streaming a video online and the audio from the video continued to download and play event though the screen was frozen.
I went to the apple store and they said they think it sounds like failure of the hardrive, graphics card, display, logic board. A new hard drive was just put in the computer about 4-6 weeks ago, and if it is the other issues could be $500-$800+ to repair. I tried to use the Apple Hardware test (non-extended test) but it keeps freezes at 2 min 32 secs every time when it starts "testing the main logic board"....
Has anyone seen anything like this and have another way to test what the problem could be? Thanks!

I know you're in denial, but it really does sound like the motherboard or graphics board which is integrated with the motherboard. Yes, fixing these things will cost almost as much as a new MacBook Pro. Get a new one, take the HDD out of your old one, and start over again.

Apple Hardware Test for iMac

I recently ran the Apple Hardware Tests. The extended test showed the following code: 4M0T/40000004: HDD - 1332. Does anyone know what this code means?

It means there is a fan issue (4MOT) on the hard drive (HDD). The 1332 is the fan speed, as I recall. It means the fan is running outside of the parameters the system thinks it should be running at. If you don't have it already, you can download iStat Pro to monitor your hard drive temperatures. It may be an issue, or something to keep an eye on, and may require a service visit.

Anyone Know what this apple hardware test error means?

Hi I've been experiencing some problems with my mac it gets to hot fans nerver go up not even with smc fan control installed and some times it freezes so i decided to run the apple hardware test that comes with the machine and during the memory part it showed me this error code
4MOT/1/40000003:HDD
Does any one know what this means or have any idea with what part of the machine it can be related to
Thanks hope sombody answers

If I had a hardware error detected by Apple Hardware Test (which in my experience misses the minor things) then I would be raising a case with AppleCare right away.

You shouldn't have to deal with hardware failures on a Mac this young.

Apple Hardware Test automatically runs?

Hello everyone,
When I turned on my 13" macbook pro today, it ran the Apple Hardware Test. I ran the test and found no errors.
Is it normal for macs to automatically run this diagnostic tool? Because ive done a quick search on the internet and it seems as if the Hardware Test runs when you insert the software disk that comes with the macbook.
There is no CD in my optical drive, and I bought the macbook 6 months ago.
So is everything ok? because it worried me quite considerably that something is wrong my by macbook.
Thanks!

AFAIK, they don't even document this in the ACMT material. That's nice. It means I shouldn't need to stock all those application DVDs at work. Usually I just load the appropriate ASD revision onto my external HDD, but that may just come in handy some day.
I'm also betting AHT is installed on the firmware chip. Honestly, the downloadable version for service techs is only like 3-5MB on average. And EFI is what a modern BIOS/firmware should be... It initializes the hardware, then hands things over to the OS and gets out of the way. You have a cheap little 32Mb or 64Mb flash chip, you'd probably have room to spare.

HT202731 What should I do next when using the apple hardware test and it will not complete. It always gets frozen when 56 seconds of testing has passed?

MY MacBook pro will not boot up correctly. When switched on a grey screen appears and a flashing question mark box.after researching I have been able to try to complete an apple hardware test by holding the D key when switched on. Unfotunately this text will not complete. Every time I try and perform this text it sticks after 56 seconds of testing and does nothing rlse. Resulting in my having to force shut down.
I know do not know what else I can do to try and solve my problem.
Any help would be grately appreciated.
Thanks.

I would install a new HDD, format it and install the OSX. Then I would connect the old HDD via USB and see if I can access the files that are on it.
If no success and if the data is important, look for recovery software on the Internet. Most have a trial that will tell you the possibilities for retrieving data but then you will have to pay for the software.
The last option is employing a professional data retrieval service. That will be expensive with no guarantee of results.
Ciao.

Apple Hardware Test Question on iMac

I did an advanced Apple Hardware test on my 09 iMac today to test it and to see what was making the buzzing sound. The advanced test revved up each fan when it tested the logic board and I can say it is the lower left fan making the buzzing, however once it reaches 2000+ RPM the buzzing goes away.
The question i want to ask is after the test the optical drive fan stayed revved up at over 2000 RPM for a few minutes after the computer restarted, unlike the other two fans that went back to normal this fan took atleast 3 mins to go back down to normal rpms. Is this normal?
Thanks
Also does the HDD run when in a hardware test? as now and then during the test I heard a weird static sound coming from the HDD.

I looked at iStat after restarting from the test and it showed that only the optical drive fan was running at high speed after the test, with the slight buzzing fan still buzzing at low speed. I could hear that the optical drive fan was slowly revving down getting slower and slower, iStat showed it was as well and now its back to normal rpm and not revved anymore. I just thought all fans would return to normal after the test unless the optical drive got hot during the test.
The buzz is not too bad and is only noticeable in a quite room but I'm more concerned about the random grind/static sound the HDD is making ever so often. The sound is very quiet but can still be heard but i don't know what it is, well I know its not the sound of a HDD breaking as I know what that hears like.
