    FAQ about SSD

    Q1: What are the strengths of YUNZE SSD in comparison with traditional hard drives?
    A1: Our solid state drive enables high-speed data transfer as well as fast system startup and shutdown. It is anti-vibration without noise, eco-friendly, energy-saving, perfect for KTV, notebook and automobile. Meanwhile, this mobile hard drive is serviceable even at -45℃-+135℃, ideal for industrial production. Besides, it adopts lightweight design, and metal shell is also available.

     

    Q2: Why time-lapse file opening arises when IDE SSD is applied, and how to solve this problem?
    A2: This problem may be related to hard drive compatibility. You can try to activate the card via new-version software, and generally, this method takes effects.

     

    Q3: Why there are messy codes after files are opened?
    A3: This phenomenon may be caused by loose contact between hard drive and computer. You can withdraw the SATA SSD and re-connect it to computer.

     

    Q4: What are the determinants of solid state disk speed?
    A4: The speed of SSD is determined by hard disk interface (SATA, IDE, PCI-E), IC, wear-leveling algorithm, original memory bandwidth, as well as design and manufacturing crafts of PCB.

     

    Q5: What may lead to low speed of server HD?
    A5: Reasons are as follows:
    1. A small quantity of chips are used for the server HD with small capacity.
    2. Data transfer is restrained by hard drive port.
    3. Task performance of IC

     

    Q6: Why there is huge difference between actual speed and nominal speed?
    A6: Potential reasons are as below:
    1. Different testing platform and environments may lead to speed difference. For example, if you use an old-type computer with performance limit, testing speed will be seriously affected.
    2. Different testing software
    3. Testing value obtained by utilizing notebook is generally smaller than that by utilizing desktop.
    4. Switchover device may also affect the testing value. For instance, if you use a hard-disk cartridge to test the speed of SSD, then speed of data passing through USB port is not the maximum speed of SSD.

     

    Q7: Is the performance of SSD affected by storage volume?
    A7: There is no relation between performance and storage volume. YUNZE hard rive still works normally even it reaches storage limit. Performance of some common file systems like NTFS and FAT32 may be degraded when storage space is insufficient. Yet, this is related to software but not hard drive.

     

    Q8: Does the body scanner at airport affect SSD?
    A8: YUNZE SSD, USB drive, storage card and phone flash memory won't be affected by body scanner.

    FAQ about SD Card

    Q1: How to format and re-partition YUNZE SD card for Windows 2000 and XP?
    A1: Please be noted that this procedure is data destructive, and you should backup the data before performing this procedure.
    1. Right click on the My Computer icon and select Management. You will be access to Computer Management.
    2. Click on Storage and then Disk Management.
    3. Right click on the drive letter assigned to the personal storage device.
    4. Select Delete Partition and Yes.
    5. Right click on the Unallocated space.
    6. Select New Partition.
    7. In the New Partition Wizard, click Next. Select the type of partition you want and follow all on-screen instructions.

     

    Q2: What are differences between FAT16 and FAT32 formats?
    A2: File name, location, file size and other information will be stored in FAT during file storage. For FAT16 format, 16 bits are used for indicating the allocation of each sector, and the cluster number is 65,536. For 32KB clusters, the maximum supported disk capacity is 2GB. By contrast, FAT32 format, supportable for a maximum disk capacity of 2048GB, effectively avoids the problem of too small capacity in the FAT16 format.

     

    Q3: What should be done if digital camera cannot read memory card?
    A3: Reasons leading to memory card read failure are as below:
    1. Power is switched off when camera is accessing data.
    2. Picture is taken during low battery.
    3. Secure digital memory card is withdrawn when camera is accessing data.
    The remedy to above mentioned problems is to avoid incorrect use. If any of the above mentioned happens, you can re-format the memory card via PC and a card reader.

     

    Q4: If a 4GB SDHC card cannot be read by card reader or digital camera, then what should be done?
    A4: Generally, a device without SDHC labeling is not supportable for SDHC card. The maximum capacity of currently available SD card (FAT16) is 2GB, and such a SD card may not work normally in a SDHC device. In contrast, the maximum capacity of SDHC card (FAT32) is 4-32GB, and can only function normally in a SDHC labeled device. Hence, when purchasing SD card, you should be clear about the maximum capacity and specifications supportable for the intended device.

  • USB Drive

    FAQ about USB Drive

    Q1: Is USB drive readily damaged due to frequent hot plug?
    A1: Theoretically, YUNZE USB drive supports hot plug. Yet, It is connected to computer via physical interface which may be deformed due to frequent hot plug. Thus, attention should be paid during operation. Besides, to protect main board and USB port, applying USB extension cable is recommended.

     

    Q2: How to remove USB drive from computer?
    A2: Please adopt the way of "Safely Remove Hardware Program".

     

    Q3: Why the capacity is only 30.9MB for the hard drive with nominal capacity of 32MB?
    A3: This phenomenon is quite normal. For vast majority of hard drive manufacturers, 1000000 bytes are equal to 1MB. However, Windows default for 1MB is 10480576 bytes.

    In addition, if there is huge difference between actual capacity and nominal capacity, we can declare that the flash drive may be damaged and should be checked by professionals.

     

    Q4: Why 1KB documents occupy 2KB or even more storage space?
    A4: You can perform right click to check flash memory property, and then you will find that information is stored in traditional FAT format and is still usable after formatted into NTFS format. Hence, it is inevitable that there is memory space wastage, which is also the reason why FAT32 appears.
