How to Read CrystalDiskInfo Results

Posted on

Do you use a thing called CrystalDiskInfo to keep the hard drive of your computer healthy? If the answer to the question is yes, you might have a hard time reading the results of CrystalDiskInfo. Fortunately, this page is for you to rescue.

Health Status is easy to understand as it is loud and clear. As for the rest of the data, it might look scary, especially for the beginners. In fact, it is easy to fix. The first thing that you have to do is to go to Function > Advanced Feature > Raw Values and choose 10[DEC}. Then, disregard the Current, Worst, and Threshold columns, and only focus on the raw values. Here is the example to help you in understanding the results better.

ID Attribute Name Current Worst Threshold Raw Values
05 Reallocated Sector Count 100 100 10 0
09 Power-on Hours 98 98 0 9875
0C Power-on Count 99 99 0 616
B1 Wear Leveling Count 95 95 0 50
B3 Used Reserved Block Count (Total) 100 100 10 0
B5 Program Fail Count (Total) 100 100 10 0
B6 Erase Fail Count (Total) 100 100 10 0
B7 Runtime Bad Block (Total) 100 100 10 0
BB Uncorrectable Error Count 100 100 0 0
BE Airflow Temperature 66 56 0 34

In the chart above, the Reallocated Sectors Count is 0, not 100 or 10. One of the most severe conditions for a hard drive is reallocated sectors. An individual sector is not considered as a messenger of a complete hard disk failure by itself. However, the store is different if the sectors are multiplying. It means it is a sign that something is not right.

From the rest of the metrics, if anything needs attention, CrystalDiskInfo will turn the color into yellow, which means caution, or red if it is bad.

ID Attribute Name Current Worst Threshold Raw Values
BB Reported Uncorrectable Errors 100 100 0 0
BD High Fly Writes 100 100 0 0
BE Airflow Temperature 63 33 45 612936677
C2 Temperature 37 67 0 60129542181
C3 Hardware ECC recovered 60 49 0 171976251
C5 Current Pending Sector Count 1 1 0 4294967295
C6 Uncorrectable Sector Count 1 1 0 4294967295
C7 UltraDMA CRC Error Count 200 200 0 0
C8 Write Error Rate 100 253 0 0
CA Data Address Mark Error 100 253 0 0

If there are a few cautions but not enough to affect the health status of the disk, you need to keep an eye on them. In this case, it is better for you to run CrystalDiskInfo once or twice in order to see if there is any change.

Do you have to panic if you get a caution or bad health status? You have to keep in mind that CrystalDiskInfo does have the ability to read the future. The best thing this program does is statistical predictions, based on the SMART data. In the other words, it is possible for the hard drives with caution to still continue working well for years, and good hard drivers to fail the next day. In conclusion, you are not in a rush to replace a hard drive with a caution health status. All that you have to do is to take a full backup of any important files instead, which should be done on every hard drive, including the good ones.

Even so, if you get a caution or a bad health status, you must follow up with a full disk scan. This process could potentially discover deeper issues with the hard drive. For those who have a caution of bad health status and want a second opinion, you can seek help from some websites that offer help. One of the most recommended is called PC Steps. All that you have to do is to leave a comment with a screenshot of your CrystalDiskInfo and the site will do the rest.

The hard drive, SSD, or HDD, is named as the most important thing of the PC. This one contains data that cannot be replaced. The sad news is, it is not about “if” a hard drive fails, but of “when” it fails. With the help of CrystalDiskInfo, you can predict if a hard disk failure is imminent, and backup the files in the right time. As you probably know, the worst part about the hard disk failure is losing all files. It is terrifying when you do not have backup data. Sometimes, you might hear the sound of clicking from the drive or you might receive a file or folder related error message. What is scary is, most of the time the drive will seem to work just fine when in fact you get a BSOD on the next reboot or a message saying that the operating system is not found.

On the brighter news, there is a good system that can statistically predict hard drive failure. It is called Self-Monitoring, Analysis, and Reporting Technology or SMART. This one is a part of any hard drive that has been manufactured the past decade.

For those who do not have any slight idea of what SMART is, it was developed by Seagate, IBM, Conner, Quantum, and Western Digital in 1995. This one was based on the earlier system by IBM. The program measures the main characteristics of the HDD, such as reallocated sectors, the read error rate, seek error rate, and so on. All of them are able to be used to predict the hard drive failure.

Unluckily, even though there have been more than half a ton of Windows versions since 1995, not any of them is able to read the SMART data. The main reason is probably for the licensing reasons. It means using the external software to monitor SMART and the health of the hard drive is needed. And CrystalDiskInfo is counted as one of the best and the most recommended programs in this field that is free for everyone.
