Confused with hardware tests / s.m.a.r.t. failing

This morning I opened disk utility and with fear read the text saying smart status failing on my startup disk. Since then, I did several backups and decided that i will most probably need to purchase a new disk.
I also did some other tests with other applications that showed different results:
Diskwarrior - Verified
Smartutility - failing
Smartreader - failing
Apple Hardware test - No trouble found
Apple advanced hardware test - No trouble found
Disk Utility 1st time - failing
Disk Utility - 2nd,3rd time - verified
For a strange reason Disk Utility changed its mind after causing me all this panic.
What do you think I should do? Is there a problem or not? Any other good apps to test the disk with?
I am in the middle of a documentary editing and don't want to think if the drive will fail in the next hour.
thanks for your time

*Regarding SMARTreporter: the status is nice and green and says verified but when doing the tests it all seems not so green..*
Furthermore SMARTutility says that at 5 problems occurred at 3211 hours that were uncorrectable.
How can I see what is the running hours of usage and what this error was and why it happened?
Adding some info in case it helps"

Power Mac G4 MDD problems with Hardware test Memory errors

I have been troubleshooting slowness and unexplained lockups on my Power Mac G4 MDD. I've had the system since 2002. I tried to run hardware test (the disk that came with my system), and I get an error message at startup:
Invalid Memory Access at %SRRO: 00034870
%SRR1: 00003030
I run mac-boot, and get another memory error
Invalid Memory Access at:
%SRRO: 056106dc
%SRR1: 00003030
Does this mean my memory has gone bad? I don't get any other screens for testing hardware.
The lockups are varied, but many seem to deal with Safari. I have also repaired disk permissions and repaired disk. I then get security error messages when I restart, and I choose to fix them, and things are fine for a while, but then it slows down some and starts locking up again.
Thanks for any suggestions,
Marbot61

Hi Marbot61,
You might be interested in the thread "error when booting from AHT CD" on this forum. Since four different users have had the same error message in two days, perhaps ram chips are actually ok, and there is something else going on with the AHT CD boot process.

Problem with Hardware Test on Quad G5

I have just set up my new Quad G5 and tried to run a big render task on Final Cut Pro. The task quits every time after a few minutes with no explanation.
I decided to try the Hardware Test to see if I was having memory problems with the 2 1GB modules that I had installed.
I removed everything connected to the computer except the display (20" Studio). The tests seem to load OK but as soon as the opening "Test choice" window comes up I get an error in the bottom left corner of the screen which says:
Warning! Memory leaks numMalloc before 49 numMalloc after 812
Reboot to reinitialize the heap
Standalone Diagnostics v24.1.2
So I thought there must be a memory problem, so I removed the 2 new DIMMs and tried again - same problem!
Do I have a bad test disk?

Hi everyone!
Many thanks for all the helpful suggestions. Here's where I am now.
I reset the PMU
I downloaded Hardware Monitor (and paid the $8!) and it tells me that everything is normal. For the Quad, this gidget monitors all the fan speeds (7 fans and 2 pumps), all the temperatures (i.e. of all 4 CPU's, logic board, memory controller, HDD, inlet and outlet temps, graphics chip - 11 monitors in all) and CPU voltages and currents.
All fans are running normally, all temps are normal, everything looks fine!
I also did an extensive memory test (using Memtest) to make sure that my extra 2GB did not have a problem.
So...... all I can deduce is that I have a weird error on the hardware test DVD!
I did also solve the other problem with my FCP rendering. I had been using a non-self-contained NTSC HDV movie in the timeline for my down-conversion/standards conversion to PAL SD standard. I found that if I made the movie self-contained it worked fine. I actually think that I might have had some bum references in the non-self-contained version (it makes use of a whole lot of previous render files) because I had transferred all the info from my old G4 and something was probably missing!!!
That's how this whole thing started - the file wouldn't render properly - always stopped after about 10 minutes. It is a very big render - it's a 1 hour 20 min HDV video and will take 45 hours to render on the Quad (over 3 days on the dual G4). I suspected bad memory so tried the hardware test, found the fan error .....etc, etc!
Now I know that everything is good so I can concentrate on my FCP projects.

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.

Can Apples Hardware test run without dedicated disk?

Apple has maid either separate disks with hardware test for each computer they deliver or it is a part of the enclosed install disk set.
I could use a disk with some kind of general hardware test or with all the tests gathered in one disk.
Is that possible?

No. Each Apple Hardware Test is designed for specific hardware. Don't try it.

Hardware test disk image

my emac purchased second hand didn't come with hardware test CD. I know that repairers and genius types can download these as disk images. Is there a way for a mere user such as myself to get the hardware test. It seems like it would be quite a benign thing to download yet it doesn't seem to be readily available. Am I missing something?

You have the option to get in touch with 1-800-MY APPLE and for a fee they will replace your Disc set.
Explain that you purchased the eMac 2nd hand and it did not come with the disc's but the Operating System is installed on your machine.
Or you can check with one of the many Mac Vendors to buy a Full Retail Version of Tiger 10.4
http://www.macmall.com
comes to mind.
Also, don't overlook the first line of defense by using the utilities that come with the operating system,
This link will provide you with several options for repair until you get the Operating System's Disc's.

My Mac is doing strange things: delaying between users, mouse flickering and bouncing, gets stuck with rainbow wheel flickering. I ran the appel hardware test and it detected an error: 4MOT/4/40000003:HDD-1233 Does anybody know what that means? HELP!

My imac is doing strange things:
-delaying between users: when closing session it goes to blue, then takes a while to appear users signin box, and then wont recognize mouse command to enter until a couple of minutes later... then everything seems alright until....
-it gets stuck between things, the rainbow wheel appears and its just delays there forever....
-and every now and then the mouse starts flickering and bouncing wildly onscreen.
I ran the appel hardware test and it detected an error:
4MOT/4/40000003:HDD-1233
Does anybody know what that means? HELP!

WZZZ answered about where to get iStat. And do check the SMART status. If it is an overheating problem due to a fan or logic board problem, your hard drive is possibly cooking itself to death. If so it isn't a faulty hard drive even though the hard drive might fail. So assuming it's a temperature problem, even if you are able to repair things on the disk with software, that is working on symptoms, not causes. I could be wrong however.
RE: AppleCare: Your iMac came with one year of AppleCare (Apple's warranty program), but within the first year you can buy 2 more years. You have to extend by the one year anniversary of purchase of the computer. Your 10,1 is too old to still be in the first year, and since you asked what it was, I'm sure you don't have it. Bottom line meaning is that whatever this problem turns out to be, you'll have to pay for it. Unless there is something like this. It is for 2011 iMacs with certain Seagate drives. You can put in your serial number for fun, but it looks like yours is too old. Lastly, some people have had Apple help them anyway if it is just out of warranty, but many have not. Your machine is one of these. Type in 10,1 in the search box. Is there an Apple Store near you? Just b/c it's out of warranty doesn't mean you shouldn't have it looked at by Apple. But no one here can say at all what Apple will or will not do.
Hope you get it taken care of!

Blue screen of death with HDD Hardware Test error on iMac HELP!!

My iMac is not starting up. It just get the blue screen of death during startup. It is a 2.66 mghz duo with 2gb 800 ram. I was able to get the Hardware test to run and got an error of 4M0T/2/40000004: HDD-1560. I am assuming it is an error with the internal hard drive since I have nothing else hooked up to the mac other than the keyboard and mouse right now. Does this code mean my hard drive is completely shot? Any help would be appreciated.

4M0T/2/40000004: HDD-1560.
Either failing or failed
You can have Apple replace the drive at a nearby Apple store or an Apple certified repair shop.

MacBook won't boot after trying to repair with Disk Utility. Cannot boot in Safe Mode. Just powers down after about 5 minutes. Apple Hardware Test says error 4SNS/1/40000001:IG0C-0.265 But I cannot find anything on the net about it. MacBook 4,1 Intel.

Hello Everyone,
I am in dire need of assistance I am hoping someone could provide. I have a MacBook 4,1 with Intel Core 2 Duo processor 4GB Ram. It is taking over 10 minutes to boot up past the gray apple screen when I turn it on. First I cleared the PRam (?) then I checked the disk using Disk Utility Verify, and it said the disk needed repairs. So I ran the disk repair and it said it was unable to fix the errors on the HD.
I did a little research and tried booting into the Single User mode, then running /sbin/fsck -fy. It said that it found errors but could not fix them. I ran it two more times as suggested and got the same result each time. I then tried rebooting and now instead of taking 10 minutes to boot up, it takes about 5 minutes on the gray apple screen and then just turns off. I started in Verbose mode to try to troubleshoot the error and it appears the last thing to come across the screen before power down is a message "Apple Yukon 2: RxRingSize <= 1024....etc".
I decided next I would run the Apple Hardware Tester. The test came back with an error code "4SNS/1/40000001:IG0C-0.265". I am very good at searching the web but I could not find any errors that had the IG0C or IGOC or any combination at the end, but plenty of 4SNS/1/40000000(1) errors with different endings. From what I can tell people are saying anything with 4SNS/1/4000000 is a logic board failure, but this computer was literally just booting this morning until I did the /sbin/fsck -fy.
Any suggestions are welcome and appreciated.
Thank you for your time.

You've a couple of issues .... when Disk Utility tells you it can't repair a drive, if the error is a soft error, like an invalid tree or node, Disk Warrior (or TechTool Pro) can handle it. However, if Disk Warrior (or TechTool Pro) can't handle it, you can erase and write zero's to the hard drive and restore to it, or you can buy a new hard drive. Sometimes running SMART Utility can provide additional insight into the health of the hard drive.
THe 4SNS error is a sensor error. You could install iStat Pro to see if something is indeed getting too hot or remaining room temp or less. You may need to take it into an Apple shop so they can use their thermal diagnostics to test and isolate it further.

How do I run Apple Hardware Test on a 2012 MacBook Air with 10.8.4?

Hello everyone,

Using Apple Hardware Test on computers with OS X 10.7 or later
Mac NoteBook and Desktop computers shipping with OS X 10.7 or later have a partition on the hard drive or flash storage that contains AHT. To start AHT on these computers please follow these instructions:
Press the power button to turn on your computer.
Press and hold the D key before the gray startup screen appears.
It takes a minute or so for AHT to start up and inspect your hardware configuration. While this is taking place, an icon appears on the screen:
When the process is complete, select your language and click the right arrow. If you aren't using a mouse, you can use the up and down arrows to select a language and then press the Return key.
The AHT console appears. You can choose which sort of test or tests to perform:
To perform all of the basic tests, click the Test button or press the "T" key or the Return key.
To perform a more thorough diagnostic test, select the "Perform extended testing" checkbox under the Test button before you click the Test button.
Note: Your test results will appear in the window in the bottom-right of the console.To exit AHT, click Restart or Shut Down at the bottom of the window.
Some Macintosh computers that shipped with OS X Lion and later 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. An Internet-enabled connection via Ethernet or Wi-Fi is required to use this feature. Internet-based AHT functions the same as AHT on the hard drive or flash storage outlined above.
The Mac NoteBook and Desktop computers listed in Computers that can be upgraded to use OS X Internet Recovery will require a firmware in order to support the Internet version of AHT. Without this update you may see the behavior discussed in this article.

Apple Hardware Test (AHT) invoked at startup with 'ALT-D' not 'D'

Although several reasonnaably reliable sources (including such page as http://support.apple.com/kb/HT1533 ) mention that pressing 'D' at startup will invoke the Apple Hardware Test startup option, at leats on my Macbook Pro 2011 with OSX Lion, EFI 2.8 it is really 'ALT-D' that invokes AHT not 'D'. Pressing the 'D' at startup simply seems to hangs bootup until I release the key.

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.

I can not perform hardware test on 2011 imac with mavericks

I unplug all devices from my iMac and held the d key and still can not get to the hardware test. The Mac store was able to perform it with a wired mouse even after I added more ram therefore I know it can be performed. Am I leaving something out?

Read the instructions in Using Apple Hardware Test.
If your iMac shipped with discs, you must run AHT while holding the d key while starting the Mac with its grey Applications Install DVD inserted in the optical drive.
To force the Internet version of AHT to load: with two fingers hold option d while starting your iMac with a third finger.

Can I run hardware test and repair a disk with Leopard using 10.3 DVD

Hi,
I'm trying to decide whether to partition and clone Leopard to my external or partition and install Tiger on the external.
My iMac came with 10.3.6 install and hardware test DVD's and they (Comp USA) gave me a Tiger drop-in DVD. I upgraded to Leopard through a family pack DVD (when I told my friend I would by one of the install's I thought I would get a DVD, but you only get an install license, oh well). By the way, Leopard runs great in my rev A iMac G5.
I'm trying to figure out which os to use on the external as a safe-boot incase something happens. If I clone Leopard onto a partition for backup/boot, can I still use the Disc Repair (not permissions) and Hardware Test from the 10.3 or Tiger DVD's to maintain that permission should something bad happen? The way I see it, i'll be able to repair permissions on both the main and external drives using Leopard's disc utility, but I'm not sure if I can repair a Leopard disk or do Hardware Test on that disc using an earlier version of OSX install/Hardware Test DVD's.
Will earlier versions of OSX repair a Leopard disk and be able run Hardware Test?
Thanks for the help,
LowBb

Yes, that seems to be the case, but I didn't do good enough research when he asked if I wanted a license for Leopard. For some reason, I had it in my mind that a Family pack came with multi DVD's for people. Maybe that's why he sold me a license so cheap. I thought I was getting a bargin, you get what you pay for.
So, I have the hardware test DVD's that came with the iMac and the Tiger drop-in is just an upgrade with no Hardware Test, you are correct.
But: (let me make sure I have this right) I should not use the 10.3 DVD's or the Tiger drop-in to repair a disc (not permissions) on a hard drive running Leopard. Is this what you are saying? I kind of thought this would be the case. If it is, I'm going to install MY stuff that I have the DVD's for on the external as an emergency boot disc.
