What is Ultra DMA CRC Error Count?

This is a S.M.A.R.T.

Bạn đang xem: Interface crc error count là gì

(Self-Monitoring, Analysis, và Reporting Technology) parameter that indicates the total quantity of CRC errors during UltraDMA mode. The raw value of this attribute indicates the number of errors found during data transfer in UltraDMA mode by ICRC (Interface CRC).

But keep in mind that this parameter is considered informational by most hardware vendors. Although the degradation of this parameter can be regarded as an indicator of an aging drive with potential electromechanical problems, it does NOT directly indicate imminent driver failure.

To get the complete picture of the health of your HDD, you need khổng lồ pay attention khổng lồ other parameters and the overall drive health.

After investigating this issue thoroughly, it turns out that there are several different underlying causes that might end up produce this particular error code:

Generic False Positive – Keep in mind that a warning thrown around by the HD Tune utility does not necessarily mean that your HDD is failing. This utility uses generic aggregated from every manufacturer, so concerning data from one manufacturer might not be concerning for another. Khổng lồ get a more accurate result, you will need khổng lồ run the brand-specific diagnostic tool and see if the same kind of warning occurs.Incompatibility between Samsung SSD and SATA Controller – If you’re encountering this issue with an SSD, chances are it’s due to lớn a conflict between your solid-state drive và the Microsoft or AMD SATA controller driver. To fix this incompatibility, you’ll need to lớn use Registry Editor lớn disable NCQ (Native Command Queue).Faulty SATA Cable or SATA port – As it turns out, you can also expect to lớn encounter this type of issue if you’re dealing with a faulty SATA port or a non-congruent SATA cable. In this case, you can identify the culprit by testing the HDD on a different machine & replacing the current SATA cable.Failing HDD or SSD – Under certain circumstances, you can expect lớn see this error warning in the early stages of a failing drive. In this case, the only thing you can vì is back up your data before the drive breaks up for good và start looking for a replacement.

Now that you know the very potential scenario that might cause this error code, here’s a danh mục of methods that will help you identify và resolve the Ultra DMA CRC Error Count error:

Method 1: Running the brand-specific diagnostic tool

Keep in mind that the HD Tune Utility is a 3rd buổi tiệc nhỏ tool that will ‘judge’ the heath of an HDD solely by comparing them against a mix of generic values.

Because of this, it’s highly recommended to lớn avoid making a decision based on HD Tune Utility alone & instead run the brand-specific diagnostic tool – The official testing tools are specifically designed for their brand products.

Depending on your HDD manufacturer, install and scan your hard drive with the proprietary diagnostic utility. To make matters easier for you, we’ve made a danh sách of the most popular brand-specific diagnostic tools:

Note: If your HDD manufacturer is not included in the danh mục above, tìm kiếm online for specific steps on your brand-specific diagnostic tool, then install and run it to lớn see if the Ultra DMA CRC Error Count is still off.

If the manufacturer-specific diagnostic tool doesn’t raise any concerns in relation khổng lồ the value of Ultra DMA CRC Error Count, then you can safely ignore the warning thrown by HD Tune.

However, if the warning is also displayed in the manufacturer-specific analysis tool, move down to lớn the next potential fix below.

Method 2: Fix the Incompatibility between Samsung SSD and SATA Controller (if applicable)

As it turns out, the Ultra DMA CRC Error Count error is not restricted khổng lồ an HDD và can also occur if you’re using an SSD.

But if you’re seeing this error with a Samsung SSD, there’s a high chance that the issue has nothing to vày with a bad cable or solid-state health – It’s most likely due to an incompatibility between your Samsung SSD and your chipset Sata controller.

If you find yourself in this particular scenario, you can fix the issue & prevent this warning from appearing by disabling NCQ (Native Command Queue) in your SATA driver.

Note: This will not affect the functionality of your SATA drive.

If this scenario is applicable, the instructions below to lớn fix the incompatibility between your Samsung SSD and the Sata Controller:

Press Windows key + R to mở cửa up a Run dialog box. Next, inside the text box, type ‘regedit’, then press Ctrl + Shift + Enter to open up the Registry Editor with admin access. When you’re prompted by the UAC (User trương mục Control), click Yes khổng lồ grant administrative access.

Opening RegeditOnce you’re inside the Registry Editor, use the left-hand menu lớn navigate to lớn the following locations, depending on if you’re using a Microsoft SATA Controller driver or a AMD SATA Controller driver:

Microsoft SATA Controller location:HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesstorahciParametersDeviceAMD SATA Controller driver location: Dword (32-bit) Value from the context thực đơn that just appeared.


Creating a new Dword value inside the Device menuNext, name the newly created DWORD NcqDisabled if you’re using the Microsoft SATA Controller driver, or name it AmdSataNCQDisabled if you’re using the AMD SATA Controller driver.Finally, double-click on the DWORD that you’ve just created then phối the Base to lớn Hexadecimal & the value lớn 1 khổng lồ disable NCQ & prevent the same incompatibility from creating the Ultra DMA CRC Error Count error.If the same issue is still occurring even after following the instructions above or this scenario was not applicable, move down lớn the next potential fix below.

Method 3: Replace the power & SATA cable

As several affected users have confirmed, this particular issue can also be associated with a faulty SATA cable or a faulty SATA port. Because of this, the Ultra DMA CRC Error Count error can also be a symptom of a non-congruent cable.

To kiểm tra this theory, you can connect your HDD to lớn a different computer (or at least use a different SATA port + cable) if you don’t have a second machine to bởi some testing on.


Example of a SATA Port on the motherboard

After you replaced the SATA port, repeat the scan inside HD Tune utility và see if the Ultra DMA CRC Error Count error is still occurring – If the issue has stopped occurring, consider taking your motherboard to lớn an IT technician to investigate for loose pins.

On the other hand, if the issue doesn’t occur while you use a different SATA cable, you’ve just managed to lớn identify your culprit.

In case you’ve eliminated both the SATA cable và the SATA port from the danh sách of culprits, move down to lớn the next potential fix below as the issue is definitely occurring due lớn a failing drive.

Method 4: Backup your HDD data

If you’ve previously made sure that you were right khổng lồ concern yourself with the Ultra DMA CRC Error Count error, the first thing you should bởi vì is backup your data khổng lồ ensure that you’re not losing anything in case the drive goes bad.

If you’re looking to lớn back up your HDD data while you figure out which replacement lớn get, keep in mind that you have two ways forward – You can either backup your HDD using the built-in feature or you can use a 3rd tiệc nhỏ utility.

A. Backing up the files on your HDD via Command Prompt

If you’re comfortable with using an elevated CMD terminal, you can create a backup and save it on external storage without the need lớn install a 3rd các buổi party software.

But keep in mind that depending on your preferred approach, you might need to lớn insert or plugin-compatible installation media.

If you’re comfortable with this approach, here are the instructions for backup your files from an Elevated Command prompt.

B. Backing up the files on your HDD via an Imaging 3rd party software

On the other hand, if you’re comfortable with trusting a 3rd buổi tiệc nhỏ utility with your HDD backup, you’ll have a lot of extra features that are simply not available when creating a regular backup via Command Prompt.

You can use a 3rd các buổi party backup software to lớn either clone or create an image of your HDD & save it externally or on the cloud. Here’s a các mục of the best cloning & imaging software that you should consider using. 

Method 5: Send your HDD for replacement or order a replacement

If you’ve made sure that the Ultra DMA CRC Error Count warning you’re seeing is genuine & you have successfully backed up your HDD data in advance, the only thing you can vì chưng right now is lớn look for a replacement.

Of course, if your HDD is still protected by the warranty, you should send it in for repair right away.

But if the warranty has expired or you have the option to lớn return it still, our recommendation is khổng lồ stay away from the legacy HDD (Hard Disk Drive) & go for SSD (Solid State Drive) instead.

Although SSD is still more expensive than traditional HDD, there are much less prone lớn break and the speed is incomparable in favor of SSD (10x more writing và reading speeds).
