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.
