So my problem is the following,
yesterday i plugged in my external HDD Lacie 1,5 TB (FAT32) into my Xbox One to watch some video's and it worked perfectly.
However, i had to transfer some large video files (more than 4GB) from my laptop to the HDD, and it appeared that was not possible with Fat32.
So i converted my external HDD from FAT32 to NTFS (with the content still on it) just by using CMD on my laptop. After the converting was complete, i plugged the HDD back into my Xbox One, and now it won't recognize it anymore? I tried all usb ports, tried a different cable but won't help :( i don't know what to do now :(
