I've a NAS-system Zyxel NSA-220 which generally works quite well (Linux-based) and allows FTP connection.
When I'm connecting locally or remotely with FileZilla, I'm usually able to delete folders and files (since I'm connected as admin user). The NAS is configured as RAID1, with two 500GB hard-drives (drive 1 = working drive, drive 2 = backup/sync drive).
The strange thing now is, that I cannot delete a certain folder or its files (even though FileZilla starts the deletion process and everything seemed to work right...), I do not get any error message - but all files are still there.
So I believe drive 2 always back-syncs to drive 1 (which of course is not the direction the NAS should function).
The only problem directory /AXIS is been fed by a webcam AXIS 207W, which pushes images via FTP to the NAS system, could this be a problem and how to narrow down the problem? Thanks.
