  • Lacie Raid stopped mounting after a firmware update

    Posted by Alan Callaghan on September 1, 2023 at 10:55 pm

    Here are the specs:
    Mac Studio – Ventura 13.5.1
    Lacie 6big Thunderbolt 3 Capacity 24TB

    Here’s the situation.

    I have been working off this Lacie Raid for a number of years without any incident. The drives all work and the last time I checked the Lacie Raid Manager they all were in perfectly working shape.

    Today. Foolishly. I decided to update the firmware for the first time ever. I followed the prompt that the Lacie Raid Manager provided. Rebooted. And no longer mounting. I tried to mount the Raid on an old iMac that has an older Os – no luck. Redownloaded the Lacie Raid Manager and installed it. No luck there either.

    I can tell the Raid is on even though the blue light is not on. I can feel the fans lightly exhausting out the back.

    I even tried this with no luck:
    Even though it’s not the same model. Just gave it a shot.

    So my question. Is there a way to re-install the firmware via terminal or delete the firmware inside the Lacie Raid Manager and have it rebuilt? Sorta like trashing the preferences FCP 7 style.

    Any ideas or troubleshooting is greatly appreciated!

    Thank you!

    Have you tried checking this website?

    There seems to be a list of firmware software you can choose from to download on your PC, which version of Lacie you had that worked before btw? Its always good to make sure when you update that all the tools you use is compatible with the latest update, if not, it would be best to hold off on the update until there is a compatibility.

    Have you had any luck figuring this out. I just upgraded my firmware, and when I finished it said I was successful. But then when I went to turn it on, no blue lights and I can hear a faint noise inside.

    Also a Mac. Mine is an M2 MacBook Pro with Ventura

    Hey Don,

    Unfortunately, no.

    The good news is the material on the drives are ok. I was lucky because my work has 2 LACIE Big 6 Raids that I was able to swap drives in, and it mounted. I had the run around trying to find support from LACIE but I mostly ran into bot customer service. I think they are now owned by Seagate, so it’s a headache to get ahold of anyone.

    Let me know if you have any luck!

    Thank you for the response.

    Luckily I don’t have any files on it. I was just hoping to use it as it is as a back-up.

    You are correct: Seagate owns them now. I was hoping that would help. But when I chat (the only option) with tech support, they are obviously using an outside, overseas contractor who know quite a bit about hard drives in general but have no specific knowledge on these units.

    If it helps, in my case, I’m pretty sure the firmware update is the issue on the controller. If I try to run the firmware update again, it says something like “your firmware is already up-to-date”. I feel this means the computer is seeing the controller but the controller isn’t seeing the drives. Hopefully I find a way to either downgrade the firmware or LaCie/Seagate comes out with a newer firmware update. I’ll let you know if I make any progress.

    Thanks again,

    Hey Don!

    Appreciate the follow-up, and would be interested if you discover a work around. I do have a whole LACIE Raid just sitting in a box that could be used for something!

    Yeah the tech support ended up telling me to take it into a Best Buy “Geek Squad” to fix it, and I thought that doesn’t seem right…

    But please do share what you find out, it could also help somebody in the future that runs into this issue.

    Thanks again,

    Thanks for the response. I will do.

    I really could use some mass storage, but I am afraid to buy anything not knowing if it will work in a few years.
