Let's learn disk initialization and basic operation..
Connect IODD to PC. At this time, if it is a desktop, the rear port, If it's a laptop, use the port with the highest voltage.
Depending on the output of the port, a separate powered USB hub may be required.
1.If the IODD is recognized normally, an initialization message is displayed on the PC.
- Format any partition to use with (NTFS | EXFAT | FAT32).In FAT32 partition, there is 4G byte file size limitation. please use that carefully.The Partition may not be first partition.
- Copy files or folders to Iodd.
- Reconnect Iodd.
- If the screen is not matched what you copyed, Press
4for 3 seconds.You can select the default partition.
3.If you are using an existing disk or an already initialized disk, press  key of IODD to check the current voltage.
Try transferring a few files larger than 4GB to IODD to make sure it works.
V-voltage value < 4.65
very dangerous.When the V-voltage value is below or close to 4.65, large files may be copied or intermittent transmission errors may occur.
In this case, you must use port the back of the PC or a powered USB hub. Otherwise, data loss and drive damage may occur.
V-voltage value > 4.65
You should be able to use it without problems in most situations, however, the instantaneous voltage requirements of large SSDs may be higher. In this case as well, the rear port of the PC, a power source USB hub can solve the problem.
If there is no problem with copying the file, Now let's go to the next step.
