Mac is causing many unsafe shutdowns to OWC express 1m2

[DeepSix]

Did you guys measure your power draw?
? The original OWC 1M2 cable is 1 foot long. A good quality 1 foot cable should not be a problem for signal integrity. Are people with the disconnects using third party cables? Cuz if so, there are a lot of sub-par cables out there.

Active cables are much less less vulnerable to dropouts / disconnects. I'm not going to hook up my new active cable yet.

Ever since I fixed my keyboard and 1M2 from waking up the mini from sleep. I haven't had any disconnects on the 1M2. So far 6 straight wake ups from sleep mode and no disconnects.

I'm going to give it a bit more time to see if this was the cause.

I'm going to keep my new thunderbolt hub because I want to run a second thunderbolt drive. I will have this drive and the 1M2 plugged directly into the mini. It seems like I may have fixed my disconnect issue on the 1M2. But I need to give it a little bit more time to be 100%

With everything working perfectly now I just hope I don't have new issues pop up after putting in the new hub. I feel I'm in the, if it ain't broke don't mess with it phase.

Quite a thread we got going.

On my external (WD SN850X) are my Lightroom image files, my Photos library, a couple of Music libraries a symlinked folder for MobileSync/Backup (5 devices), some relatively dormant folders and a partition for a clone of the Studio. About 3 tb, out of 4, in use, pretty much constant data access, more than the internal.

I’ve been using Jettison since Mountain Lion primarily on MacBooks. Never had an issue. It dosen't eject a drive if it’s in use. At times I see a delay in sleep so I assume it has sufficient intelligence to subsequently invoke sleep. When I wake the Studio the drives are back before my ASD, which as any ASD owner can attest, is very fast. On the website is an FAQ dealing with oddball situations and how to deal with them.

Thanks. Bookmarked.

Jettison FAQ

I was getting some warnings, and bought Jettison, I have 3 enclosures hooked up. No power issues on my end from the Mac Studio.
