I have a mecool mk6 with AndroidTV 10.
I hook a SSD → Samsung 970 EVO Plus 1TB → using an external HDD case USB 3.1 to the box. The box recognized the HDD and I can format it as an external device (I don't want to get all app etc. on this External HDD).
As soon as I want to try to add a directory or file I get the notification that the external HDD named "Android" is readonly !!!
If I hook it to a windows 10 machine I can write on the external HDD without any problem. When I put it back on the Mecool MK6 read only again.
Anyone knows how I will get this external SDD mounted to be writable?
Try to format it to exFAT if is NTFS.
