TOS system will be installed to the new hard drive automatically. It will lead to RAID rename when installing TOS system separately for each hard drive, and only one hard drive's data could be shown with all hard drives inserted . In this case, please do the following steps:
    1. Backup data: power off the device, insert any one of the hard drive and power the device on to backup the data
    2. Delete the RAID: go to TOS Control Panel>Storage Manager > RAID, select RAID Volume #1 and click Delete

  • Can D2-310/D4-310/D4-300/D5-300 be used with Windows and Mac computers?

    Yes, only when the hard drive is in ExFAT format. A hard drive in ExFAT format easily fails to read and write during abnormal operations. For example, you pull out the USB cable, remove the hard drive, and shut down the power suddenly before the product is ejected properly from the computer, and thus the hard drive may make an error where it can read but not write. Therefore, we do not recommend using ExFAT format. In order to avoid damage to the hard drive or loss of data when using ExFAT format, please be prudent in your operation to make sure RAID storage devices eject normally from the computer before you remove the USB cable and hard drive and shut down the power. If the above scenario happens, please try to reboot the device.

    The hard drive can read but not write in Mac computers when it is formatted into NTFS.
