I plugged my 1tb external hard drive I made (bought enclosure and drive separate) into my phone to back up files, I downloaded an app with good reviews that could read and write to a ntfs drive via an otg cable. its called total commander and paragon_UMS. It took awhile to load and stuff,(Changing file system? or somethin) and I could read and write asit said, but when I plug it int any laptop mac or desktop it lags and the drive runs at 100% in task manager(trying to repair?) I went as far as installing linux and using Gpart to try and solve but the same there(even if I put it in the desktop) I know files can easily be read its just getting over the first hurtle.
