Mobile hard disk identification help 10, how to identify the quality of mobile hard disk

1.Identify whether it is **! The outer packaging of the mobile hard disk, the fuselage itself has a SN code, and the official website is checked, and these serial numbers are unique in the world.

2.Then use the tool to scan, it is recommended that HD Tune can find out whether the hard disk has bad sectors, the speed of the hard disk, and the actual performance of the hard disk.

HD Tune is a hard drive performance diagnostic test tool. It can detect the transfer rate of the hard disk, the burst data transfer rate, the data access time, the CPU usage, the health status, the temperature, and the surface of the disk scanned. In addition, the firmware version, serial number, capacity, cache size, and current transfer mode of the drive can be detected in detail.

The steps to detect a portable hard drive with HD Tune are as follows:

1. Install HD Tune on your computer.

2. After installation, insert your portable hard drive and turn on HD Tune.

3. Select the name of the mobile hard drive you want to detect in the box.

4. At this time, various data indicators of the mobile hard disk you purchased will pop up. Click on the "health" tab, there is an entry under this tab called "power an hours count", the numbers in the third and fourth columns of this row can tell whether your portable hard drive is brand new or not, if it is brand new, both values are 0.

5. Double-click this entry, a value named "description" will appear below, the value roughly means the use time of the mobile hard disk, if this number is "0", it means that the mobile has not been used, it is new.

Each hard drive has a unique ID when it leaves the factory, just like the engine number and ID card, because the anti-counterfeiting measures of various models of hard disks are different, providing you with the following ways:

1.Go to the local or nearby customer service center (repair point) of the mobile hard drive brand for consultation2Browse the official **, check the authorization information, the original price, the authenticity identification method, generally speaking, the factory price will not be less than 70% of the marked price, and the bargain that is too low is naturally fake.

3.Some commodity boxes have anti-counterfeiting marks and query methods, but some counterfeit products look the same as the real thing, and there are anti-counterfeiting marks, but the anti-counterfeiting marks are fake. Counterfeiters have seized the psychology of consumers who don't want to bother to make a query, so that we think that there is an anti-counterfeiting mark that is true and will not inquire or anything.

The above is my personal advice, I hope it will be helpful to you.

First, the appearance of the product:

The outer ** of the Western Digital mobile hard drive looks like a book, the Western Digital logo is located in the lower right corner of the product, and the original Western Digital mobile hard drive currently sold in the market has 7 colors: bright black, red, daylight yellow, raindrop blue, mint green, fresh pink, arctic white (the outer layer is painted with piano paint, the color is bright and textured).

Second, the product serial number:

All ** original Western Digital mobile hard drives have a three-year warranty and free replacement service! There are 12 digits of S n number at the bottom of the outer packaging of the mobile hard drive, which can be checked by dialing 800-820-6682 for Western Digital after-sales service**, and reporting the S n number! (The S n number is located on the label at the bottom of the product, and the part circled in red can be checked in Western Digital to see if it is genuine).

3. Product packaging:

The newly packaged Western Digital mobile hard drives are all packaged in plastic packaging with 2 labels on them: 1)."Synnex goods"; 2).Original factory with Western Digital logo, quality assurance triangle sticker (in the upper left corner of the outer packaging).

Upstairs is right. It is best to buy the core and case separately for mobile hard drives, but the money may be more. How do you talk to JS? Just seeing the core is the best way to identify a portable hard drive.

Query the anti-counterfeiting code through anti-counterfeiting**, or query through the PN SN of the hard disk.

The authenticity can only be queried by the anti-counterfeiting ** query anti-counterfeiting code, or through the pn SN query of the hard disk.

The capacity issue is normal and not explained. Inside those files when syncing software and backup software.
