how to fix LaCie hard drive keeps crashing on macOS Sonoma

I updated my Mac Ultra M1 to macOS Sonoma and had nothing but external hard drive failures. After updating, both of my LaCie drives would not mount, I was able to repair one and got it to mount. But then a day later the drive failed to mount again and repairing it did not work with Disk Utility. I have two LaCie 2big 40 TB raid drives. I've since reformatted them, I wiped my Mac Studio clean and did a fresh install of macOS Sonoma. The drives worked fine for a couple of days, but then again one of the LaCie drives was not mounted, so repairing would not work. I did not have any issues before upgrading to macOS Sonoma. I've been using these drives for a year without problems. Is anyone else experiencing corrupted LaCie hard drives when using macOS Sonoma?

Some basic checks to fix the corrupted LaCie hard drive

Before diving into any professional solutions, let's try some simple checks to make the LaCie hard drive functional. Each trick will be elucidated in detail, and you can perform it successfully though you're new to macOS and LaCie hard drives.

Re-connect the LaCie hard drive

When the LaCie hard drive behaves mistakenly on your Mac computer, you can give it a re-connection. Safely eject it and unplug it from the machine, then insert it into the Mac post to see if it works normally.

If you use a drive adapter, cable, or reader to connect the hard drive and computer, give it a replacement!

Restart your Mac

You may not be able to determine which side contributed to the LaCie hard drive failure, whether it falls on the Mac or the hard drive per se. Anyway, it doesn't matter. A device reboot helps end any strange error or bug hiding in the Mac background: open the Apple Menu > click Restart from the menu.

When your Mac wakes from the restart, check if the  LaCie hard drive works fine.

Force mount the LaCie hard drive

If the LaCie hard drive doesn't mount on Mac, you can force mount it in Disk Utility. Here I'll show you how to do that:

Step 1: Launch Disk Utility on a Mac computer via Spotlight Search or Finder > Applications > Utilities > Disk Utility.

Step 2: Select your hard drive in the left sidebar of Disk Utility.

Step 3: Click the Mount button on the top menu bar of Disk Utility.

Check the file system of the LaCie hard drive

When the LaCie hard drive is read-only on your Mac, you should consider its file system. Due to the proprietary issue, a Microsoft NTFS formatted drive doesn't receive any writing action from Mac.  

You can either format the drive to a Mac-compatible file system or utilize an NTFS for Mac to mend this gap. Formatting a drive means you need to wipe the drive completely, while NTFS for Mac doesn't have that need.

Check if the NTFS for Mac supports macOS Sonoma

Some NTFS for Mac utilities delay the update to support macOS Sonoma, resulting in your failure to write to an NTFS-formated LaCie hard drive as normal. In such cases, iBoysoft NTFS for Mac is highly recommended which always follows Apple's update and offers full support to newly-released macOS, including macOS Sonoma.

Update drivers of LaCie hard drive and macOS

Regardless of whether the LaCie hard drive driver is non-updated or the Mac driver is outdated, it will hinder the LaCie hard drive from working. Under this circumstance, you should check if there is any driver update available on the Mac. 

Go to Apple Menu > System Settings > General > Software Update, and then complete the update if there is any available.
