Why XferMax X8 does not include internal storage and battery?

Hard drives or solid state disks are easier to damage in international logistics. Lithium batteries are dangerous goods that are under the supervision of air transport, so it brings many difficulties to international logistics and transportation. Furthermore, rechargeable lithium batteries and hard drives or solid state disks are relatively easy to buy from the local market, and the price is relatively transparent. Therefore, we adopt a policy to sell casing(no battery, internal storage) to the international market.

What is the difference between “Copy to Card” and “Copy/Paste” feature?

“Copy to Card” and “Copy/Paste” is not the same feature.  The aim of the “Copy/Paste” feature is to prevent data loss during data backup. The XferMax X8 will process data backup with a series of steps. It includes data reading from the source, comparing data with an original piece of data, then writing data into a destinated disk as long as copying data is the exact one from original data. As a result, the copying performance between these two methods is different.

About Virus warning

You may find some virus warning when using anti-virus software to scan the HDD/SSD of XferMax x8 series products. Please do not worry about it.  In order to make device operating normally, XferMax creates two copies of the firmware that acts as OS of the device.  It includes the original code developed by dazuinfo and other open source code of third parties like Mplayer.  One copy of firmware stored in flash, making device running normally. The other firmware copies to your local SSD or HDD in case the flash firmware damaged. In this extreme case, the device can still work normally by using the firmware in your local SSD or HDD. It can avoid a return to the factory for repair.

All software is based on ARM architecture and only runs on XferMax series devices. Namely, it will not damage any data based on other operating systems like Windows, etc. Some of the virus warnings can be identified as an improper reaction. And the mission of dazuinfo is to protect the valuable data for our customers. We have no purpose to endanger the business principle of our own business.
