My iMac recently updated to macOS Sierra 10.12.1 Beta (as I was participating in the beta program)

Unfortunately this appears to have firstly re-organised my iTunes library (all my Movie/TV files were moved into the Home Video folder)

My iTunes library is on an external Volume (LaCie 5Big RAID drive). At first in trying to re-build my iTunes library I discovered I was unable to add any content

Subsequently found that I was unable to add ANY Video content to my LaCie drive - received the dreaded -36 error message

e.g

The Finder can’t complete the operation because some data in “filename.mp4” can’t be read or written.

(Error code -36)

On further investigation it seems that I can’t copy .mp4, .m4v, .mov, .dmg, .mp3, .pkg, .pages, .keynote files...

However copying some other file types to the drive is OK (e.g can copy PDF files, txt…)

Also unable to launch/run video files (as they are copied into iTunes Media Folder - which is on external LaCie drive!)

"Attempting to copy to the disk “LaCie” failed. The disk could not be read from or written to."

(Removed the setting under iTunes Preferences - and can run, but leaves file where it is)

Did some digging around on and tried to clean this up using the dot_clean utility - unfortunately without any luck

Ran Disk Utility - My drive appears to be clean (Apple Disk Utility seems to have lost many of its features)

Ran LaCie Raid Manager - Integrity of the LaCie Volume looks fine - although the notifications are a month behind (see attached screenshot)

I am able to copy ALL files to the external drive using cp from within a terminal window.

I connected the LaCie 5Big drive to my MacBooK Pro (running El Capitan 11.11.6) - and everything appears to be fine - can copy Video files etc - so nothing wrong with the drive!

Have attached a LaCie 1TB ruggedised drive to my iMac and I can copy files to the drive without issue

So problem appears to be with LaCie 5Big RAID (20TB) drive and macOs Sierra 10.12.1 Beta

(updated this morning to the latest beta version and problem still there)

Anyone seen same issue or know how to fix this ?

LaCie support acknowledged an issue in its kernel extension and promised to deliver a fix soon.

We have just been informed about an issue with 10.12.1 which is officially not released yet.

A debug is being arranged at this stage and should be fixed before the release of 10.12.1.

For the moment, the advise is to fall back on 10.12 and away from the beta OS.

The updated version of LaCie RAID Manager will be released soon with the fix.

Cheers

At least, they acknowledged it. That's fine.

Yes I had a similar acknowlegement from LaCie too

My previous response to you is currently being blocked...Seems to be some random algorithm that the forum is using to block responses !

I plan to wait until the fix is out - as I am able to mount the Array with my El Capitan machine.

Believe there is a problem on macOS Sierra with permissions on /Volumes

I have this same issue with the LaCie 5big Thunderbolt 2 with 10.21.1 with Lacie Raid manager 2.0.3.1057.

I guess, 2.0.3.1057 is firmware version; and LRM is something like 2.1.3.4853, right?

Just updated to macOS 10.12.1

Also updated the Firmware on the LaCie to v2.0.3.1058. LRM is v2.1.3.4853

No difference!

So just updated to the latest LaCie Raid Manager v2.2.5.5711 (which was released as I was typing up the issue) and that appears to have fixed the problem....

So hopefully back in business!
