Etcher cannot recognise 'SanDisk Cruzer Blade' flash drive under OS X.

[UniK]

• Etcher version: 1.0.0-beta.13
• Operating system and architecture: OS X 10.11.6; Kernel Version 15.6.0; x86_64
• Do you see any meaningful error information on DevTools? No
• Sytem Console Messages: (not sure if relevant)

- Etcher[43486]: BUG in libdispatch client: kevent[EVFILT_MEMORYSTATUS] add: "Operation not supported" - 0x2d
- Etcher[43486]: assertion failed: 15G31: libxpc.dylib + 78286 [54D1328E-054E-3DAA-89E2-375722F9D18F]: 0x89

I have two of this flash drives, and both are not visible for Etcher under OS X.
They are both recognised by Etcher running on Ubuntu 16.04.

Hey there,

Thanks a lot for reporting. We use a module called
drivelist to detect the
available drives, so something might be going wrong there.

Can you run the following Bash script while the problematic drive is
plugged in and share the results?
https://github.com/resin-io-modules/drivelist/blob/master/scripts/darwin.sh

The output of the following commands would also be useful:

• diskutil list
• diskutil info /dev/diskN, where N is the id of the problematic
  drive.

Hey there,

Thanks a lot for the reports. So the issue is that your operating system detects your drive as non being removable, which causes Etcher to omit it for safety reasons (see Removable Media: No in diskutil info).

I don't think there is much we can do from our side (I don't know what to do if your operating system doesn't think its removable). I suggest to either:

• Find a way to be able to tell (or trick) your OS that the drive in question is indeed removable.
• Enable the "unsafe" mode in Etcher (see the cog at the top right corner), so Etcher doesn't filter non-removable drives (but proceed with caution of course).
