Ejecting mkII fails [Resolved]

[Mint-Gecko]

Ejecting the Electra One mkII storage from the OS fails on both of my machines (MacBook Pro 2021 with Ventura, PC with Win10). Both OS simply won’t do anything when triggering the eject command from the file browser. I only found two workarounds to successfully eject the disk without simply plugging out the cable:

• on macOS
  • open the disk utility
  • select the Electra One storage
  • click the “Unmount” button in the top-right
  • wait some seconds until it’s greyed out, now reset the device before macOS mounts the storage again
• on Windows
  • open the “Device Manager”
  • under “Disk Drives”, look for an entry called “NULL NULL”
  • right-click on that and uninstall the driver

Also, ejecting the device on Windows via the system tray menu isn’t possible at all since the entry is missing:

Would it be possible to name the disk something like “Electra” on Windows? The Explorer just calls it “USB Drive” and the device manager lists it as a meaningless “NULL NULL”.

I completely reflashed the device with @martin 's instructions and ejecting now works as expected (tested on macOS Ventura, Win10 and Manjaro). It does take some seconds on macOS but it succeeds eventually.

The disk being called NULL NULL in some places like the Windows Device Manager is still happening, although that’s just a cosmetic issue. It’s also called like that in several places on Linux:

Just in case it helps testing and bugfixing, this is what happens on Ubuntu:

When USB mode is enabled, it is recognized correctly but without name:

When ejecting, it works. See how the NULL NULL that @Mint-Gecko has reported above is reproduced here.

One detail, after the device has been properly ejected, the E1 display still shows “USB Disk enabled”. Ideally it would go back to “enable USB Disk”. Not a big deal.
