Error code when running Apple Hardware Test

2STF/8/3:B (lower) error code when running Apple Hardware Test.  What does it mean?  Test won't let me go beyond this point.

    After more research on other sites, this error does indicate a potential hard drive failure.  Thankfully, the drive is still functional, just making periodic noises and slowing down quite a bit.  I have 2 hard drives in my system, so with that, I used SuperDuper! to create a bootable back up and just switched my OS to the other drive.  OS is working fine on the second drive (which DID pass the extended hardware testing).  Time to shop for a new drive!

    Thank you for your response and help.

    Ran AHT on my G5 with a similar error code as Keesus. Under the category Mass Storage - error detected, error code 2STF/8/A (upper). The test was terminated at that point. Any advice would be greatly appreciated.

Its an issue with the hard drive in the lower slot. The volume may be corrupt of the drive could be physically damaged. Did you install the bottom drive? is it the drive with the OS installed?

What does this error code mean...4SNS/1/C0000008 TL0P==124

It's a temperature sensor error, usually the fans run at maximum rpm when this happens. The error indicates the LCD temp sensor is either reporting out of range data, is disconnected, or has failed. It is probably a damaged or disconnected sensor cable. A disconnected or missing sensor would simply force the fan(s) to run fast to protect the system.

That error code means your HDD is dead..
It may be corrupt; it's unusable.
You will need a new SATA HDD.

Source: Google and my experience with that error in my Macbook Pro. var fctb_tool=null; function FCTB_Init_c051884345bf42a4a9c154223e7d2f63(t) { fctb_tool=t; start(fctb_tool); } FCTB_Init_c051884345bf42a4a9c154223e7d2f63(document['FCTB_Init_6e224391880b406abfb85fe687432776']); delete document['FCTB_Init_6e224391880b406abfb85fe687432776']

My macbook air hardware test shows error code 4HDD/11/40000004: internal. What does that mean and how do i resolve the problem?

The meaning of Apple Hardware Test results is Apple proprietary.
That having been said, it appears that AHT is reporting a problem with a hardware component associated with your hard drive (the drive itself, a drive temperature sensor, or something else). An Apple Authorized Service Facility will be able to give you more information.

I dropped the laptop now at start up there is a disk error


It seems to me the Hard Drive is faulty. You can check/run a test on the laptop to see if there is a hardware problem.

1. Turn on computer
2. Tap F12 continuously on the Dell logo screen
3. Select Diagnostics
4. Follow on screen instructions
4. Wait for the test results (approximately 10-15min.)

If there is an error code, it means there is a hardware problem, but if all test passed. It means it is a software problem. You can send me the results (If there is an error code) so that i can tell you which hardware is faulty.

Error code 1b63:161b and 1b63:061b

Hi there,

Request to try the steps below;

1. Restart the computer and tap the f12 key as soon as it starts to boot up .
2. Select 'Diagnostic' from the boot menu. The computer will run its pre-boot assessment tests (PSA) before Dell Diagnostics starts. During the PSA you will hear some tones through the system speaker but this does not adequately test the audio hardware. Dell Diagnostics plays an instrumental piece of music complete with drums, so if you only hear some tones then you have only run the PSA.
3. Dell Diagnostics should open after the PSA tests, or you should see an option to open it. If you have ever reformatted your entire hard drive then Dell Diagnostics will no longer be there as an option. In that case run it from the Drivers and Utilities (Resource) CD if you have one.
4. Select 'Custom', then the audio tests. (At this point - after you have opened Dell Diagnostic custom - if you can't find the option to select the audio tests that is a symptom of a failed audio chip.)
5. The tests will run. Alternate between using headphones and listening to speakers in case only one signal path is working.
The tests will play some audio and ask you whether you heard it.
6. If you don't hear the music during the test it definitely means there is a hardware failure somewhere in the system. In this case Dell will repair the computer if it is still under warranty.
7.If you do hear the audio during the test but not when you boot back into Windows, that almost always means the hardware is okay but there is a problem with the audio driver or with Windows.
8. Error codes: If you answer 'no' to any question that the test asks you, the test generates an error code that can tell a Dell technician that you answered 'no' to that question. The test does not know the exact component that has gone bad. Before answering 'no' to a question, make note of the circumstances at that point so you will know in general what the error code means.

Wont read/write hard drive

use Apple Hardware Test to diagnose the error::
1 Disconnect all external devices from your computer except the power adapter.
If you have an Ethernet cable connected, disconnect it.
2 Insert the Mac OS X Install Disc 1 that came with your computer.
3 Restart your computer and hold down the Option key as it starts up. A list of available
startup volumes appears. Click Apple Hardware Test and click the right arrow.
4 When the Apple Hardware Test main screen appears after about 45 seconds, follow the
onscreen instructions.
5 If Apple Hardware Test detects a problem, it displays an error code. Make a note of the
error code before pursuing support options. If Apple Hardware Test does not detect a
hardware failure, the problem may be software related.

If I could be of further assistance, let me know. If this helps or solves the issue, please rate it.
Thanks, Joe
