After an apple hardware test on my iMac I got an error code ?

So I did an extended hardware test on my apple imac and after an hour of testing i got this error code: 4MOT1/140000003: HDD-1363. The next day I did another hardware test on my apple imac but this time iI did a quick hardware test and after about five minutes of testing this time I got the same result except this time the 4-digit code or number after the 'HDD-' changed to a different one, like... 1476. So what does this mean, I mean my computer is working perfectly fine without any problems (except for that one time when my brother punched my iMac's screen really hard a couple of times and a couple of hard punches on the hard drive however it was working fine but he did it again and it froze the time he did it again and i had to restart it but everything was STILL working fine after I restarted it !) but when I do the Hard ware test I get those errors so what does this mean ? Is it possible to fix ? Would apple fix it for free as my warranty has expired ?
All help appreciated
Thanks

don't know why, but try using Disk Utility to repair the drive:
1. Insert the Mac OS X Install disc that came with your computer, then restart the computer while holding the C key.
2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu. (In Mac OS X 10.4 or later, you must select your language first.)
Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.
3. Click the First Aid tab.
4. Click the disclosure triangle to the left of the hard drive icon to display the names of your hard disk volumes and partitions.
5. Select your Mac OS X volume.
6. Click Repair. Disk Utility checks and repairs the disk.

Error Code After Running Apple Hardware Test

I ran apple hardware test (I'm having problems where my computer freezes for like 10 seconds with the mouse being movable... but it happens very frequently. like once a minute. it's SOOO ANNOYING)
this is the error i got after running apple hardware test:
(it came out as a Mass Storage error... which is Hard Disk i guess)
**ERROR*CODE***ERROR*CODE**
2STF/8/3: S-ATA Bus 0-Master
**ERROR*CODE***ERROR*CODE**
Does anyone know what I can do to fix it. Apple Hardware Test only allows me to find the error and then restart or shut down... which is useless cause what is the error code supposed to mean. I've only got Apple 1 yr repair support left... so I cant call up Apple or anything. Does anyone know anything about this and what I could do to fix it!?
I know about this: http://www.apple.com/support/imac/repairextensionprogram/
I might go to the apple store, but I dont wanna make a trip out there for nothing.
Does anyone know what I can do or should I just take it to the apple store.

Actually, i just spent like 1 hr working with disk utility using the os x install disk and i think it finally worked. im so happy for myself! yay... i wouldnt accept no for an answer. Disk utility kept saying "oh first aid failed because it didnt exit right" or something... total garbage response... i kept pressing verify disk and then repair disk and then i did the verify permissions and repair permissions too... didnt really know what i was doing with the permissions... but it finally worked so thats all that mattered! yay... its back to normal!!

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.

Is it possible for Apple Hardware test to make mistakes ?

I have done an apple hard ware test a couple of months ago and got an error code. I managed to fix it with some help. Now I did it again after a couple of months and it showed me the same error code again but I have no problem with my
iMac (sluggish, crahshes etc...). My iMac is C-O-M-P-L-E-L-Y fine in terms of performence. So is Apple hardware test wrong ? I heard that the error code is due to it being on for so long... But I need to approve it... Is it serious ?...
All help appreciated
Thanks

One common source of false positives is from connected peripherals. Did you disconnect everything except Keyboard and Mouse?

Apple Hardware Test Non-existent on Imac 27" i5 with preinstalled Lion!!

Have just spent nearly 30 mins on the phone with AppleCare because I can't seem to get the Apple Hardware Test on my iMac to work. Checked in instructions and it states "Restart iMac while holding down D key" - that does not work. Then it states, "if the Apple Hardware Test window doesn't appear after restarting, hold down the Command, Option and D keys and restart the computer to access the AHT software from the internet". That doesn't work either. When talking to AppleCare the chap told me to use my disk - don't have one! Went through the same thing I tried from instructions and still doesn't work. Has anyone tried using the AHT with Lion preinstalled? Have you got it to work, or is it just me?
Any help/advice much appreciated.

Thanks for your reply. It seems that some iMacs running Lion are able to run AHT or gain access to an Internet version. I, unfortunately, am unable to do either. There is nothing in the instruction book relating to non-access to AHT if you are running a pre-installed version of Lion. Perhaps Apple should have at the very least included an info sheet stating what Lion runs and does not run! The more I find out what has changed in Lion the less I like it. I have had iMacs since the revised G3 which I think was back in 1998. I have had several iMacs since then and really liked all of them. This one I don't. If I can find a way of running Snow Leopard, I will junk Lion.

Apple Hardware Test (Perform Extended Testing)

Hit the 'E' key to select Perform Extended Testing if you are unable to select it with a mouse.
I've been working on my wife's new iMac (I7 27") that she purchased a few months ago. Because it is so new, I wouldn't even waste my time on it and just sent it back to Apple to have them look at it (currently suffering slow startup times), however we recently moved overseas to Kyiv, Ukraine. During the troubleshooting, I found the following site:
http://support.apple.com/kb/ht1509
which informs users how to use Apple's Hardware test. Unfortunately, the app only recognized the wireless keyboard and not the wireless mouse. I didn't know who to contact to have the webpage updated because there is a way you can enable the extended hardware test from the keyboard (by hitting the 'E' key). Unfortunately, I had to figure this out on my own after exhaustive searching on the internet and websites. Hopefully, someone can pass this information along. I wish the app was more keyboard friendly.
I see some other posts that I haven't tried yet, so hopefully they might resolve me issue.
If I can't fix the problem, I'm going to have to see if there may be a rep in this country who to replace/fix the unit.
Kevin

Yesterday I ran the Apple Hardware test ( Version 3A181 - Perform Extended Testing ) from my MacBook OS Install DVD and Everything passed 100% ( entire test took 57 minutes and 15 seconds )
Forgot to mention after the Apple Hardware test was finished No Problems Were Found...
This isn't making any sense to me - Any Suggestions to what the cause of these Safe Boots may be ?

How do you start the hardware test on an imac with bluetooth keyboard

How do you start the apple hardware test on an imac with a bluetooth keyboard as the instructions is to press the D key whilst restarting? And of course the imac cant see the keyboard whilst booting up as the bluetooth connection has yet to be established

Have you tried following the directions for running it from the DVD? The instructions are on the Hardware Test link.If you are correct and it cannot due to the wireless keyboard not making a connection you will need to borrow a wired USB keyboard.

Apple hardware test detected an error.

Well, I'm back (see older post) . Just ran Apple hardware test and it says it detected an error. What should I do from here??
I using the original Tiger discs which came with the computer. The Leopard disk was just a drop-in CPU disc they gave me to upgrade from (when I purchased the iMac in 07). Can I just use the Tiger disc again to run Disk Utility and try to fix the HD?
Nancy

Attempted to repair disk via the Disk Utility on the Tiger disc.
Now receive new messages:
under Verify & Repair Macintosh HD:
Error: The underlying task reported failure on exit.
uner 1 non HFS volume checked:
1 volume could not be repaired because of an error.
I think I'm toast. Can anyone tell me what to do at this point?
Thanks,

Apple Hardware Test Error Messages

I ran a hardware test on my iMac and the following error message appeared.
4MOT/4/40000003:HDD-1243
What does this mean?
Thanks guys,

What prompted you to run the Hardware Test?
As far as I can tell, it's either an error with the Hard Drive or with the drive temperature sensor. If it were the latter, the fan cooling the drive would be operating out of its normal range.
Get iStat Pro and post the fan rpms, and temps, along with specifics on the model of your iMac.

Hi,
It can take a few minutes for the AHT to appear after booting, D key, etc:
http://support.apple.com/kb/HT1509
Try shutting down your iMac, reboot and THEN do the AHT.
Are you able to boot from the restore disk?
To check the hard disk:
Open Disk Utility, in the Utilities folder in the Applications folder.
Insert your Mac OS X Install disc in your computer’s optical drive or an optical drive connected to your computer, and then restart your computer. When you hear the startup tone, hold down the C key until you see the progress indicator, which looks like a spinning gear.
Follow the onscreen instructions until the Menu Bar appears with the Utilities menu in it, choose Utilities > Disk Utility, click First Aid, and then click the Verify button. If DU reports errors, click Repair. When it's finished, from the Menu Bar, select Utilities/Startup Disk. In the Startup Disk window select MacintoshHD 10.x.x and click Restart.

My Mid-2011 iMac with pre-installed Lion can't load AHT (Apple Hardware Test) over internet

I have a Mid-2011 iMac (3.4GHz) of which Apple's Support document for the Apple Hardware Test (http://support.apple.com/kb/ht1509) says:
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.
Well, this doesn't work for me. My Mac is on a DHCP-supporting router which has constant internet connection. Yet, when I turn off the Mac and then on again, holding the D key down even before the screen turns on, the Mac does indeed react to this key as it's then turning the screen on and taking another about half minute before it continues with the boot process along with showing the Mac symbol. Without the D, the Mac symbol comes up quickly.
So, it appears that the iMac is indeed trying to get AHT over the internet. Just that it doesn't succeed in it, and probably timing out after a while.
Any suggestions how to fix this?

Re
extract from kb article
PPPoE (where there is no router handling the PPPoE connection)
No
No
Captive-Networks (where you click an "Agree" button to access the Internet)
Yes
No
Proxies (where specific proxy servers must be configured in network preferences)
No
No
Certificate-based authentication / 802.1x
No
No
try check if you are in that case for your internet acces ?
could be a firewall problem too , if is possible try desable firewall ( or any internet filter )
no you can not see a wifi selection if you are wired ( using cable )
by the way D key for AHT need to be pressed AFTER start up sound , and hold at min one minute
HTH

IMac intel late 2006, lost DVDs, how to run apple hardware test

Hello, Applers,
I have an iMac intel core 2 duo late 2006. I have upgraded it to snow leopard. From two months ago, it began to show distorted pictues, random lines/pixels/, and regular freezing. But if I boot it into the safe mode, it works well, although there is no sound or webcam. I did a research online and it seems that I should run apple hardware test (AHT) first. But the DVDs came withi this machines have been lost. where can I download this software? I would greatly appreciate your help if any of you who also have this model of machine and would like to lend me your DVDs.
any suggestions are welcome.

You can purchase replacements from AppleCare:
Apple Store Customer Service at 1-800-676-2775 or visit online Help for more information.
To contact product and tech support visit online support site.
There is no way to run the AHT without the discs.
If it works OK in safe mode then you might think about:
Resetting your Mac's PRAM and NVRAM
Intel-based Macs: Resetting the System Management Controller (SMC)
Reinstall Snow Leopard:
Reinstall OS X without erasing the drive
Do the following:
1. Repair the Hard Drive and Permissions
Boot from your Snow Leopard Installer disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu. After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer.
If DU reports errors it cannot fix, then you will need Disk Warrior and/or Tech Tool Pro to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
2. Reinstall Snow Leopard
If the drive is OK then quit DU and return to the installer. Proceed with reinstalling OS X. Note that the Snow Leopard installer will not erase your drive or disturb your files. After installing a fresh copy of OS X the installer will move your Home folder, third-party applications, support items, and network preferences into the newly installed system.
Download and install the Combo Updater for the version you prefer from support.apple.com/downloads/.

I want to run apple Hardware Test but can't find it on any CD's. I bought my iMac in 2009. I think it had 10.4 installed. It's not on my installation disk. Where can I find it?

I want to run Apple Hardware Text but can't find it on any CD's. I bought my iMac in 2009. It came with 10.4. Apple Hardware Test is not on the installation disk. Should I have it? Where can I find it? I"m now running 10.7.4.

The disc plainly state:
To use the AHT, hold down the D key as the computer starts up.
Works here. However, there was an issue with installing Lion that screwed this process up.
Mount disc 2, run this command in the Terminal app, OPTION-click & hold Finder's Dock icon, and select RELAUNCH:
defaults write com.apple.finder AppleShowAllFiles 1
That unhides all hidden files/folders.
Now, drill down to /"Applications Install\ Disc"/System/Library/CoreServices/ and drag the .diagnostics folder into your Lion boot volume's /System/Library/CoreServices/ folder. That might require you to authenticate to copy the folder into the CoreServices subfolder.
Run this command to hide the normally hidden files/folders and RELAUNCH the Finder again.
defaults write com.apple.finder AppleShowAllFiles 0
This should allow the machine to boot into AHT when restarting and holding down the D key.
If that doesn't do the trick, run this command in the Terminal app:
sudo chown -R root:wheel /System/Library/CoreServices/.diagnostics
At the Password: prompt, carefully type in your admin password, since nothing shows up on the screen, and hit the return key. Then, try another restart, holding down the D key.
