If your smartphone is really old, if you no longer have the box or if you are not sure of its model number, you can either enter the secret code Android to discover it, or use the application Chainfire: USB Host Diagnostics.

Discover the advantages and disadvantages of OTG

Maybe you are already familiar with the OTG. The term "OTG" may not tell you anything but it is the technology that allows you to read a USB key (or a hard drive) and more generally to use USB ports on an Android device.

That said, there are some conditions to make sure your external drive is well recognized.

All USB compatible devices are usable as long as they do not require external power. In addition, your device (hard disk or USB drive) must be in FAT 32 format, media in "NTFS" will not be recognized. If your disk / cl is not this format, you can of course format it and put it in FAT32 but then you will lose your data, so be sure to save them elsewhere before.
