Error code - 4MOT/4/40000003.HDD

Can anybody please give me some advice on what the above mentioned error code is as my iMac is failing to do anything except start up,
Thanks Mark.

Hi,
Try these below in order, to check whether you can boot the machine further:
Intel-based Macs: Resetting the System Management Controller (SMC)
About NVRAM and PRAM
OS X: About OS X Recovery to confirm that the internal disk is accessible.
Afterwards, try a normal reboot.
If the machine is still not booting:
Refer: Hardware Test 4MOT/4/40000003: HDD-1326
and Using Apple Hardware Test
Cheers

Buy a new drive and replace the old one. While the old one is still working (if it is) I would quickly make a bootable backup to an external drive if you have one, assuming you have no extant backup.
Clone using Restore Option of Disk Utility
Open Disk Utility from the Utilities folder.
Select the destination volume from the left side list.
Click on the Restore tab in the DU main window.
Check the box labeled Erase destination.
Select the destination volume from the left side list and drag it to the Destination entry field.
Select the source volume from the left side list and drag it to the Source entry field.
Double-check you got it right, then click on the Restore button.
Destination means the external backup drive. Source means the internal startup drive.
You will find suitable replacement drives at OWC.
They may also have a video tutorial. Or you may find a written tutorial at ifixit.com. Also may find one by Googling for it.

Alternatively, contact Apple Service, iMac Service or Apple's Express Lane. Do note that if you have AppleCare's protection plan and you're within 50 miles (80 KM) of an Apple repair station, you're eligible for onsite repair since yours is a desktop machine.

I run a hardware test and it gave me the error code 4mot/4/40000003:HDD-1500: does anyone know what it means?

Hello,
I have a problem of my iMac freezing up regularly for no obvious reason.
So I ran a hardware test and it returns me only with the code 4MOT/4/40000003:HDD-1500.
I need some help to know what that means and how to repair my iMac.

William, unfortunately it means your hard disk drive has or is failing and needs to be replaced. Hopefully you have a current backup or clone. You can have the drive replaced at an Apple Store or AASP or do it yourself if you're inclined by following the guide fir your specific iMac at http://www.ifixit.com/Device/Mac_Desktop

After installing a new hard drive the fan is very noisy. Hardware test error code 4MOT/1/40000003: HDD-1417

I've carried out all the trouble shooting procedures.The fan is running @ 3899rpm and the temp is 26 deg celsius. (I'm assuming the sensor is working OK...it may not be) A SMART test was OK, can anyone please identify the code and suggest a solution.
Thanks

There are temperature sensor on the Apple installed hard drives. Did you reattach this to the new drive? If so how well / badly was it stuck on? Was the sensor damaged during the install of the new drive?
The fact the fans are running @3899rpm shows something is not quite right.
Is it possible the new drive is faulty? See here:

Hope this helps

i just did an apple hardware test and this is what i got. my imac running slow. it hangs and stutters often.

Error message 4MOT/4/40000003:HDD-1278.

After hardware test, my iMac is showing error message 4MOT/4/40000003:HDD-1278 Should I be concerned? Best, Paolo

Yes Paolo, you should be concerned. That error code indicates the fan that cools the hard drive has failed or is failing. You'll likely need professional help to overcome this.

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.

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.

I believe you've posted this multiple times. Once is all that's needed. Also, please don't use all caps. Aside from the fact it means you're shouting it's also harder to read than mixed case.
The error means a bad fan motor or the HDD has failed. In your case it's the latter. You can try the following:
Drive Preparation
1. Boot from your OS X 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.
2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Note the SMART status of the drive in DU's status area. If it does not say "Verified" then the drive is failing or has failed and will need replacing. SMART info will not be reported on external drives. Otherwise, click on the Partition tab in the DU main window.
3. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, set the partition scheme to GUID then click on the OK button. Click on the Partition button and wait until the process has completed.
4. Select the volume you just created (this is the sub-entry under the drive entry) from the left side list. Click on the Erase tab in the DU main window.
5. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, check the button for Zero Data and click on OK to return to the Erase window.
6. Click on the Erase button. The format process can take up to several hours depending upon the drive size.
When formatting has completed quit DU and return to the installer. Complete the OS X installation.

AHT Error message - 4MOT/4/40000003: HDD - 1248

Hi folks........ i'm looking for some help on a AHT error message?
The error message is 4MOT /4/40000003: HDD - 1248
Has anyone any ideas what this is?
Thanks
Paul

You're looking at a drive issue, possibly heat and or fan related. Google is pretty good at pulling up posts for the error message.
If the system is still working and the drive is accessible make sure you do a backup right way and then make an appointment with Apple.
good luck

Hardware test Alert Code: "4MOT/4/40000003:HDD-1229" on 2011 27'' i7 iMac. HELP

Hello,
last week I found out that some files on my mac were missing so I desided to do an hardware test.
when the test finished I got the following alert:
"4MOT/4/40000003:HDD-1229"
What does it mean?
Thank you,
Aviad

The hard disk fan sensor is damaged. Make a backup of your files and take the computer to an Apple Store or reseller to have your hard disk replaced.
It's possible that Apple reinstalls the Mac OS X version you have onto the new hard disk, so you just have to make a Time Machine backup and restore it during the initial setup of your computer. Also, if Apple installs a blank hard drive, you can use Internet Recovery to restore your Time Machine backup > http://support.apple.com/kb/HT4718

Error code 4Mot/1/40000002:HDD-0

With the following error will I have to replace both the hard drive and HD fan?

Probably either the fan motor, a temp sensor that controls it, or the logic board part that handles info from the sensor to the fan. Mot means motor and HDD is the hard drive, so it's something to do with the fan that cools the HDD. No matter what, be sure you have a backup b/c you're likely on borrowed time. Only an Apple Store or service provider can tell you what needs to be fixed.

Failure Code 4MOT/1/40000003: HDD?

Is it an HDD failure or the issue is only with the fan?
if it is only with the fan, does this means that my HDD is still alive?
if the issue is with the HDD, does this means that i can't back up anything from it?
you advice will be highly appreciated.

I think it's only the fan, not the drive. But if the drive isn't being properly cooled, you could end up ruining that. iStat Pro, which can display temperature and fan speeds, used to be widely available, and it may still be from some disreputable sites that package adware along with downloads. like Softpedia and CNET.
I've found it here. Can't guarantee this site either, but at least I haven't heard anything bad about it.
http://mac.majorgeeks.com/files/details/istat_pro.html
Otherwise, no fan speeds, but entirely safe.
Temperature Monitor
Or Hardware Monitor, which does show fan speeds, but not free. Something like $10 when I got it.
