Hi, I have a Vu+ Duo 4K SE that has previously worked fine. Lately I have started hitting some minor difficulties with certain files not being readable via Samba and this has escalated to difficulties getting the disk to mount. I had problems with it a few days ago and had to run fsck a few times, with intermittent problems also getting the disk mounted. I thought the problems were overcome and yesterday it seemed fine, but after a regular overnight reboot the disk is not mounted and my attempts to get it remounted have failed. I have tried rebooting, also to no effect. I took the caddy out and put it back in, again to no effect.

As far as I can tell the physical device is recognised:
- it appears as a Detected Device in Main Menu ---> Information ---> Devices
- it is listed in Main Menu ---> Setup ---> Storage ---> Filesystem Check
- it appears in Main Menu ---> Setup ---> ViX ---> Mount Manager

Can anyone suggest what might be the problem? Am I right in guessing that this is a hardware failure? If so, is it likely the HDD or the Vu?

I've attached a couple of log files from /var/log. They contain a number of sections that indicate some sort of failure (see below) but I don't know if this is relevant to what I'm seeing.

Many thanks for any advice.
Dan
