Dear Maintainer,

Usually to copy an iso image to a USB stick I would do: dd if=image.iso of=/dev/sdg

"/dev/sdg" the path to the USB key checked in the logs.

Today with version dd (coreutils) 8.32, this command replaces the block device /dev/sdg with a /dev/sdg regular file which has the same size as the iso image.

Is it a bug or a new feature?
I couldn't find an option in the man page for this new feature.

I used the pv command instead of dd, and I copied the iso image to the usb stick. pv image.iso > /dev/sdg


Regards.

dd didn't remove the device file. I suggest that you remove the usb
stick, remove the device file, insert the usb stick, check that the
device file is actually there and correct, then try again with dd.

Hi,

Thank you for your reply.

Yes, Friday I was on my PC at work. I tested this weekend on my home PC,
and didn't have this problem. I retested on my PC at work and I no
longer have this problem.

The bug report can be closed.


Regards.
