External Drives Not Recognized After Upgrade

I have two LaCie 5Big Thunderbolt Series Raids, (20TB each) daisy chained and attached to my Mac. They are set Raid0. In Yosemite, they are recognized and work well.

I upgraded to El Capitan yesterday and saw that the drives were not showing up in Finder. After searching and not finding any hits about LaCie updates to the drivers, I went back to Yosemite from backup. The drives were there again.

This morning, I downloaded the LaCie Raid Monitor software and installed it just in case it might help. I then upgraded to El Capitan again and the drives, again, were not seen in Finder. I reached out to LaCie support to find out if they were aware of the issue and if a new driver was coming out. The person I spoke with informed me that they have not had any other reports. She had me open Disk Utility to see if the drives are seen there. Oddly, 3 of the drives are recognized, the remaining 7 are in an "Untitled" status.

She asked if the drives were attached when I did the upgrades, and they were. She speculated that the upgrade process, specifically Spotlight, could have done something that messed with how the OS sees the drives. Her recommendation is to go back to Yosemite, disconnect the drives and do the upgrade again. Once it completes, re-attach the drives and see if they are then recognized. I see some value in that and will do it later today. I wanted to get on this forum, however and see if anyone else has experienced the same or similar with any of their external drives, LaCie brand or not. If so, how have you resolved it?

I've been approaching this as an issue with the LaCie drives, but is there Apple liability here as well? I'd appreciate any insight on how to resolve this. Again, I can stay at Yosemite and everything will work fine, but I'd like to use El Capitan if there's a way to make this work.

Hard to agree it is not their (Apple and LeCie) problem.

The Little Big Thunderbolt2 1TB SSD is available to buy worldwide.

In any case it always includes 2x 512GB SSD drives, so it is just a question of time when new users are going to get problem with RAID.

Anyway, I am ready to spend 49$ more if I can be sure http://www.softraid.com/ will work making 1TB RAID again.

Do you have any input regarding low level terminal operations I can try to use ?

Best Regards,

Widom

Here are the links I have thus far on using the Terminal on my Little Big Disk now that Disk Utility has been dumbed down:

Thanks to WRS_AIA and DWhillans, I don't have an older Mac with thunderbolt and Yosemite at hand but finally heard back from LaCie tech support offering another solution: Disconnect all internal drives from the 5Big Thunderbolt2 and then turn on again. Now the device shows up in Raid Manager and can be updated with the latest firmware which solved the problem. The 5Big Thunderbolt2 is now mounting again.

We are having the same problem but with a Western Digital Thunderbolt Raid.

Dec 9, 2015 7:44 PM in response to bettyfrommonticello

My problems started when I installed the 10.11.2 update a few days ago. My Lacie 2bigThunderbolt (4Tb) drive no longer appears. The drive is working away but nothing shows up on the iMac.

I have tried the Lacie Raid Manager (BTW - the login screen is the same as your computer) but it does not see the drive. I will try using an "old" Macbook Pro running Yosemite but am not too hopeful. Then I will try the Softraid software.

We had a similar problem with a WD Thunderbolt attached to our server. I don't exactly know which step solved the problem but that's what we did:

Shutdown the server

Disconnect Thunderbolt cable

Restart in Safe mode

Zap PRAM

Shutdown

Reconnect Thunderbolt cable

Restart in normal mode

Voila... Drive showed up again...

The problem reappeared a few times. We repeated the procedure (without the PRAM zapping) and every time the drive would reappear. It's been working now for a few weeks without problem.

Mike,

Here is my earlier post that worked!

When I upgraded to El Capitan my computer would not recognize my Big5 Thunderbolt 2 Drives. After several weeks of discussion with the technical department at Lacy they concluded that an upgrade in firmware was required to solve the problem of drive identification.

Correct firmware is 2.0.3.1057. Most hard drives are carrying 2.0.3.1056

Link to the firm is below:

Firmware: http://www.lacie.com/files/lacie-content/download/drivers/5big-firmware.bin

Mac Pro (Late 2013), OS X El Capitan (10.11.1), Lacie Big5 Thunderbolt 2

Lacie Has Solved My Big5 Problem Using El Capitan 10.11

Dec 9, 2015 8:20 PM in response to WRS_AIA

Thanks for the tip but Lacie RAID manager does not see the drive so I don't see how I can install the firmware update (in any case there does not seem to be a firmware update for my older Lacie drive - it was mentioned above that it might involve a software update).

I have installed SoftRAID Lite and it sees the Lacie Volume and 2 disks but is unable to mount them.

I will try a PRAM reset next (while I wait for a Yosemite Macbook Pro to arrive)

I updated my firmware using "Yosemite" and then plugged back into my El Capitain

Dec 10, 2015 9:54 PM in response to WRS_AIA

No luck with the Yosemite MBP. It did not mount the Lacie drive. Yosemite Disk Utility "saw it" and reported that it needed repairs (ominous!) but was unable to complete repairs. So it looks like the Lacie drive has become corrupted. In any case there does not seem to be a firmware update for this model.

Grrr! (this used to be appropriate when OSX was named after big cats)

Is there anyway to update the firmware through El Capitan? The Lacie website never said anything about first update the firmware then upgrade to El Capitan otherwise your Raid Manager won't show any device and you can't do anything! Mine has slow blue blinking light as an idle mode every time I plug it even though I have the latest Raid Manager but can't see any device to update the firmware.

We usually get the new updates inside the new OS not the other way around. Anyway, given the fact this is practically an Apple-product ready storage and it is mostly compatible with Apple devices this is highly inconvenient.

Please let me know if you can find a way to fix this through El Capitan.

Mazlyar,

You can't update through El Capitan. You must go to a computer with 'Yosemite" to update the firmware ob the disk. The blue blinking light means it can't connect to a computer. My earlier link provided a link to the latest firmware, which i got directly from Lacie. The Apple Store may have a laptop you can use?
