Up until last week my two year old R6 24TB 32 Promise Pegasus was mounting on an Intel iMac running Monterey without issue. Then I moved it... about 2 feet away and I was very careful with it and didn't drop it or bang it.
So this morning it wouldn't mount on the iMac. I unplugged it and moved it onto a different part of my desk and connected it to my MBP laptop and after much plugging and unplugging the TB cable and power cable it mounted.
No errors or anything.
So I unplugged it and plugged it back into the iMac and it mounts on the iMac. I then power everything off and it doesn't power up on restart.
I then unplugged power ejected the drives and reseated them and connect power and TB and it mounts again...
computer restart and no dice, it wouldn't mount.
I also have a R4 Pegasus 3 that is mounting like a champ everywhere I plug, intel iMac, Intel MBP and M2 Ultra Mac Studio.
The Pegasus 32 take multiple power cycles or hard drive reseating as described to mount on any of these three computers.
Pretty sure it's not a driver issue as it was working just fine on that iMac until I moved it.
Thinking it might be something more mechanical maybe? I was going to take a look inside incase it's clogged with dust or something like that.
Any other ideas or experiences I'm all ears if anyone has had a similar problem.
