UI Hang

I’ve tried Firefox, Chrome and Safari all work (don’t work) the same. I haven’t tried connected directly to my computer but can. There is over 2TB of data and 200,000+ files that are all important and they are currently backed up but it took over a week to do all those copies. I was planning to power cycle but I think it is absurd that a RAID drive is so fragile. I already had to pay over $3000 to recover the files lost by this dirve once.

thanks,
