I have been having issues with my pegisis R6 since i had a drive failure. It was a 6TB unit that i then replaced with 6 x 4TB drives and set up in raid 6 with a hot spare. once is was all set up, it has been dropping out/ ejecting from my imac. I would have to unplug the thunderbolt lead and plug it back in again, and then after a while (60 sec maybe) it would show up again. then ofter a few minutes-hour the mac would send a warning about ejecting a disk properly as the raid droped out again.
Then this morning, i can not get it to mount or be recognised by the imac at all.
I also note that the power button appears to no be responding. pusshing it or holding it does nothing.
I am wondering if there is an internal power supply issue maybe like filter caps or something causing issues.

Any tips would be great as this is used as out primary photo storage.
