External SSD Disconnects Repeatedly Mac Mini M1 (Big Sur)
Has anyone had an issue with your external SSD's on Thunderbolt (and a few times on USB3) just randomly disconnecting? It disconnects and reconnects instantly and comes back online after tossing a notification not to disconnect a drive without hitting eject.
I'm still trying to root cause this, but my hypothesis is that it's an Intel / Rosetta emulation issue. I've only been able to have this occur on drives that have an Intel process attached and writing to it (reading doesn't seem to cause it). And, it's not every single instance / case.
Adobe Premiere:
Exporting a from from a video as PNG or whatnot with a destination to that drive causes the notification to pop up around 60% of the time. It feels as though the longer the system is up the more likely the notification is (and sometimes it won't write the file, other times it will write and notify).
Dragging those same files from the main disk using the Finder, however, works fine (as does exporting from a native app like Pixelmator Pro).
Google Backup & Sync:
Upon boot one of my external SSD's gets hit with repeated disconnect notifications and I noticed that it's being 'synced' by Google Backup & Sync (as that's my destination for Google Drive). Once google drive is idle and done syncing, the notifications stop.
Unfortunately when exporting a video in Premiere to with source media on one of the SSD's, if google backup/sync runs and causes a disconnect, the video export will render out out "black" in the spaces in which the drive "blipped" offline for a moment.
Still trying to find use cases and track down how/when it occurs. One experiment, I moved all the SSD's off thunderbolt and onto a USB hub (with a few adapters and such) and the problem went away...but one of my other USB drives started getting the notification once or twice a day. So odd...
Thoughts? Want to share any information?
This is a 500GB Mac Mini M1 running 11.1 (16 GB memory).
Brand new system, my old mac's did not exhibit this problem but they also were not M1's and they were not running Big Sur.
PS: Also cannot reproduce this using Black Magic Speed Test against these SSD's even though it's Intel and it's doing large writes (maybe it's small writes that exhibit it easier?)
