We've had a support request from a customer site which has a number of BrightSign HD220 and HD1020 units, recently 3 of the HD220 units all displayed the same error message onscreen:
"The attached storage device is write protected. Remove it, enable writing, and reboot the device."
The SD cards have not been removed from the players at any point and we don't believe any additional content has been programmed to the units recently, also all three came up at the same time. The units are all setup for Local Network updating which was tested a couple of years ago and all worked ok. Given that no changes to the SD cards or the programming have been made, do you have any suggestions as to how we can resolve this issue and what has caused it?
