So I want to preface this with the fact of just how much I love OWC. I have been buying their gear for many many years, and it has always been very reliable, and they have amazing customer service. I have had them replace ram, and quickly get back to me on issues for years and years.
Lately though I have been a few issues, and this post is about one of them.
So I have a fairly new
Thunderbay 4 Thunderbolt 3 and am running a full version of OWC’s amazing Softraid to run it in RAID 5. It is way too small with 4 2TB drives, for a 6TB raid. I am on an iMac Pro running Catalina 10.15.6 and all the sudden have been getting drive drops often on waking up from sleep, or when restarting, forcing a quick rebuild or making me restart to get the drives back. And constantly having the drives be out of sync, though Softraid fixed this in a minute or two each time.
Now it hasn’t happen while I was working and I haven’t lost anything, but it has been annoying.
Now while looking at their forums for another issue I will post about in another post,
I ran into this post about Disk Ejecting a firmware update. I quickly downloaded and went through the steps to install. It basically says it has to do with allowing drives to sleep in the energy saver control panel, but this firmware should permanently fix the issue.
As with most things of the sort it is made a bit of a longer process, because of having to disable SIP or System Integrity Protection, and is a multi-step process since you have to then install a kext file, restart and then eject your drives, and install the firmware update.
Now this is where I would add a note to the process, because while the instructions said it would take about 30 seconds, once I selected the firmware and hit the FWUpdate button. It did not take 30 seconds, in fact my computer sat beachballing for well over 30 minutes, before it successfully did the update. This is fine if it fixes the issue, but 30 SECONDS IT DID NOT TAKE!!!
The process then has you uninstall the KEXT, turn SIP back on restart and then turn back on all of your networking which you have turned off earlier.
When I restarted the final time Softraid again said the drives were out of sync, but lets hope that has fixed the issue.
