I am trying to burn a 2GB ISO image onto a 64GB USB drive which has been formatted to ex-fat and GUID partition map using Etcher 1.5.86.
Running on iMAC under High Sierra.
I had no trouble burning to an 4GB SD card.
The process stops with oops etc.
Any suggestions?
Thanks,
Peter
Hi there Peter,
If possible, please provide us with any console log output when this failure happens. You can access that console following the instructions here: https://github.com/balena-io/etcher/blob/master/SUPPORT.md#forums
This is from the System Log after last attempt to burn USB drive.
The process completed and the Etcher dialogue box said burn successful.
But iMAC says disk unreadable.
Here is the Syslog at the time of completion.

Is this the log you were looking for as there are numerous available on the Console utility.

Perhaps the read problem is just a Mac thing as I was able to
read it on my Linux box.
Odd that I have to format the USB and then copy a file to it
before I can get Etcher to burn a bootable drive.
If I don’t copy a file to it he burn fails.
Thanks,
Peter
Hi @PTPI, nice to hear that you managed to resolve this issue. Indeed, it’s expected that MacOS cannot right away read the Etcher flashed image as it is a Linux filesystem. From Etcher perspective, it actually sounds like everything is working properly and normally.
Could you elaborate this new issue you posted? Does Etcher show any error when you flash before you need to format USB and the copy a file yourself?
I wouldn’t expect that as Etcher supposed to format the USB drive before the flashing begins. Let us know the error you see. Screenshot of Etcher and copy of Etcher console logs would help (press Cmd+Alt+I within Etcher to open DevTools and copy paste the error logs you see)
Cheers…
If Etcher formats the drive what format.
The USB drive I have is 64GB so must be formatted exfat.
Thanks,
Peter
Actually you don’t need to do any kind of preparation or formatting before using Etcher. Etcher doesn’t deal with filesystems, it just blindly copies an image file contents byte by byte to the drive.
In order to be able to assist you better screenshots of Etcher and copy of Etcher console logs would help (press Cmd+Alt+I within Etcher to open DevTools and copy paste the error logs you see).
Do you experience the same issue when you try to flash other USB drives / SD cards?
When I used Etcher to flash a 4GB SD card it worked flawlessly.
The DVD burner on my iMAC is defective so can’t try that method but will soon have a new external DVD writer so will try it then.
Thanks,

Ok, thanks for the context Peter. You won’t need the DVD burner in order to use Etcher,
