[Q] Can't unmount or properly mount HDD
So I bought an OTG cable for the first time yesterday, and I tested it with a pendrive. I could access the pen with Root Explorer, on /mnt/ntfs/sda1, but there was no option to mount/unmount the drive (the android system did ask me to erase the pen because it had a damaged filesystem, but I could access it with no problems with Root Explorer).
So what I want is to be able to unmount the device so I don't damage it over time, or properly mount it on a more logical path so I can use it with other apps.
I also tried an WD HDD of 1.5TB and the same thing happen, I could access it on the same path but no mount/unmount options anywhere. Not even "filesystem is damaged" warning this time.
I have tried with some Play Store apps (root required ones) but no luck.
Thanks in advance.
