Keep errors and bad sectors at bay

Keep errors and bad sectors at bay

Lesser external drives continue to work even when dropped or encounter a shock, resulting in errors and bad sectors. With ADATA’s proprietary shock sensors, all drive activity will cease when a physical shock is detected. Once in the clear, activity resumes. You're kept fully informed with a clear status indicator.

More space to back you up

In an era of 4K UHD and 8K video content gigabytes just don’t cut it anymore. With up to a massive 4 TB of storage space the HV300 has you covered and ready to back up all your music, movies, photos and more.

*The figures shown here are based on the 4 TB variant of the HV300.

  • A: Please click here for more information.‎
  • A: In Windows XP, you can partition disks through Control Panel / administrative tools / computer management / disk management. Select the installed hard disk, and press the right mouse button, and select the option to partition the drive.‎
  • A:

    1. Safely Remove: Please use the "Safely Remove Hardware" function before unplugging the hard drive to prevent data corruption.

    2. Avoid Collisions and Drops: When in use, please place the hard drive on a stable surface to avoid vibrations or impacts that could damage it.

    3. Prevent Overheating: Keep the hard drive well-ventilated during use and do not place it in high-temperature areas or direct sunlight.

    4. Stable Power Supply: Prioritize using the USB ports on the computer's main unit and avoid using unpowered USB hubs.

    5. Be Mindful of Viruses and Information Security: When using the hard drive between different computers, please use antivirus software and protect your personal data.

    ‎
  • A: There may be compatibility issues with certain security programs for mobile devices that are completely unrelated to the external SSD. Most Android device manufacturers themselves do not guarantee compatibility with such apps. If the OS of your mobile device freezes, reboot the mobile device. If this fails, please contact the device manufacturer.‎
  • A:

    The reasons for an external hard drive producing unusual noises could be aging, abnormalities in the circuit board, or read/write tracks. It could also be caused by the read/write head module inside the hard drive being displaced due to impact.

     

    If the hard drive emits metallic clicking sounds and experiences slow read speeds or computer crashes, it is recommended to immediately back up your data, unplug the hard drive's power cable, and send it for repair.

    ‎
  • A: 1. Connect the drive to your Windows PC
    2. Open the Disk Management tool. You can do that by typing "disk format" or "disk management" in Windows search or going to Control Panel > Administrative Tools > Create and format hard disk partitions
    3. Right-click on the external drive partition or the unallocated space you want to format and choose New Simple Volume
    4. Follow instructions to choose a volume size
    5. Assign a drive letter
    6. Choose the file system in the Format Partition screen
    7. Give the volume a new name
    8. Click Next
    9. Click Finish
    10. Formatting complete‎
  • A: If data transfer is interrupted, make sure that the error was not caused by a lack of power. If a transmission interruption occurs, please reconnect the device and retry the data transmission. In theory, data will not disappear because of interruptions in the transfer process.‎
  • A: We recommend that you use the Safely Remove Device function before disconnecting the cable between the external SSD and your Android device. Failing to do this may cause copied files to become corrupted and unreadable.‎
  • A: The external hard drive requires a start-up current of over 600 milliamps, however USB 2.0 can only provide a maximum of 500 milliamps. As a result, it is recommended that you use a Y-cable we using with a USB 2.0 host devices.‎
  • A: Differences in size shown are mainly due to differences in computer operating systems, the calculation method for an external hard drive capacity, and the Controller IC’s operations result in different ways. Generally, hard disk manufacturers usually calculate capacity based on the decimal system, and computer systems are actually binary. Hard drive manufacturer: 1KB = 1000 Bytes, 1MB = 1000KB, 1GB = 1000MB, 1TB = 1000GB
    Operating system: 1KB = 1024 Bytes, 1MB = 1024KB, 1GB = 1024MB, 1TB = 1024GB
    So for example, a hard disk marked as 500GB capacity is 500GB = 500 x 1,000MB x 1,000KB x 1,000Bytes = 500,000,000,000 Bytes, but in binary the capacity is calculated as 500,000,000,000 Bytes / 1024KB / 1024MB / 1024GB, approximately 465GB.
    Fastest method of calculation: the hard disk capacity x 0.93 = the approximate actual hard disk capacity‎
  • A: Solid State Drives (SSD) are storage devices like hard drives, but with much better performance, especially as regards random access speeds. But because of their higher price, they are often more suitable to be used as the drive from which the operating system is run. The slower speeds of HDDs mean they are likely to be used as data backup media, and for data archives.‎
  • A: UASP stands for USB Attached SCSI Protocol. It combines SCSI commands and USB standards to accelerate data movement and make file transfers more efficient. If your device does not support UASP, you may update it from the device manufacturer website, as UASP functionality can be added via firmware or operating system update.‎
  • A:

    Backup ToGo does not support an encryption function. Use of built-in Windows encryption software BitLocker is recommended (click here to enable BitLocker encryption mechanism on Windows 10 devices).

    Standard plastics are generally extracted from petrochemical raw materials, while PCR materials are produced from plastic particles after recycling, sorting, crushing, screening, and washing, with different proportions of additional newly produced plastics. Products made of PCR materials have undergone strict verification and testing to ensure that the recycled plastic meet the highest quality requirements and will not affect the normal use and durability of the product.

  • A:

    The FSC™ or "Forest Stewardship Council" is an international forest management certification framework. This framework has established a series of standards and principles to ensure that the production and consumption of forest products such as wood and paper achieves an optimal balance of environmental, social, and economic impact. Using FSC™-certified products can ensure that these products come from certified sustainable forestry, thereby protecting the forests’ ecological environment, biodiversity, and forest resources, and help companies fulfill their social responsibilities.

    ‎
  • A:

    PCR or "Post-Consumer Recycled" materials represent items discarded by consumers after use that are recycled, sorted, processed, and then reused as new raw materials. ADATA's HC300 ECO external HDD and UC310 ECO UFD consists of 35% PCR materials, which come from transparent 5-gallon water jugs and vehicle headlight housings. Using PCR materials in products can reduce demand for new materials, waste generation, environmental burden, energy consumption, greenhouse gas emissions, and also help promote a circular economy and realize the sustainable responsibility of corporate ESG. 

    ‎
  • A: There are two general possibilities :
    ● Lack of power: The hard disk should be attached to the USB power cable connector into the USB slot on the back of the computer. Make sure your computer supplies enough power for the hard disk to run. Do not use a USB Hub, extension cord, or other USB devices together, because doing so may cause power undersupply, resulting in the external drive being unable to be read.
    ● Volume has not been added: In Windows XP/Vista/7 operating systems, go to Disk Management to confirm that the hard disk is installed.‎
