And what Doug mentions is key. I too have often wondered about some kind of LaCie specific sleep behaving controller buried in the machine. And wondered if I could access it with one of their apps. But it ultimately seemed a fool’s errand with no value added, so I gave up (plus it seems those LaCie apps wanted to add on all sorts of low-level extensions deep within the OS and again, just didn’t seem worth it to me).
Typically, what I do on any given harddrive it take it out of the box and format it directly with Apple’s Disk Utility (DU). I’m not interested in anything they generally bundle with it, such as security apps or drive controllers, or . . . Now there are other software RAID controllers such as SoftRAID, but I don’t have any experience with it, and Apple’s DU has generally been “good enough” for my needs.
And note, there are instances of hardware-based RAID controllers, but those are typically on more expensive RAID setups that generally use a software app to get to the controls of the hardware. ATTO products come to mind–though there are others.
In terms of the geek speak, the reason I mentioned what I did is because some of the problems you’re experiencing “could be” related to a mismatch of some kind. Like using the Apple Partition Map instead of the GUID Partition Map. Or APFS (on spinning disks) instead of Mac OS Extended (Journaled). Much like the use of 3.1 USB-C vs. the Thunderbolt slot.
One “gotcha” to look out for when using Apple’s DU is the difference between viewing Only Volumes and viewing All Devices. Think of All Devices as the core harddrive (say all 1 TB of a 1 TB drive), and Volumes as sub-parts of the drive (or partitions), where you could have two 500 GB volumes on a 1 TB drive. Volumes that you can mount and unmount independent of one another. Or you could just keep it all as a 1 TB volume, or. . . . But anyway, as you’re playing around with these things, that’s one that can trip someone up, especially when it comes to formatting a drive.
My encouragement would be to unmount (and disconnect) all drives, and then get something you don’t care much about, like say a scratch drive where you can lose everything, and then start poking around at the different ways to format something in DU.
Joby.
