Hello!
Sorry fo my bad english. Open-E NAS-R3 - 8 HDD (8*1Tb) – Seagate ST31000340NS
Have a next problem. There are three network drive, for example - Air, Capture, Edit.
Copying video to disk "Edit" - storage has stopped with error-“No access. Remove the write protection” in Windows notification area. Empirically found that this problem occurs when working with network drive "Edit". Work with "Air" and "Capture"- all normal. In the boot process everything is fine - without any errors. System loaded normally, but when you try copy on “Edit” again this error repeated again and again.
In system events (web-interface log in)- warning messages.
