I recently bought a Samsung note 10.1 tablet. Samsung note doesn't recognise my 1 Tb hard drive using usb 3.0 Y cable. It's showing usb mass storage connected but can't access the file. Please help me to solve this problem.

Is the drive formatted as FAT32 or NTFS?

Hi
No, I don't know how to formate my drive.

Without external power you can't use the HD.
It needs more power ,your Note 10.1 can't deliver it
