Imager does not save .img files correctly while other program does. about rpi-imager HOT 7 CLOSED

There is a bug in which verification fails if the image size is not dividable by 128 KB.
You should not have a problem writing official Raspbian images which are a nice round number of megabytes large though.

Thank you for your reply. As I wrote before, even writing official buster image leaves SD card unpartitioned...

What image exactly?

It is normal for partition table to be empty if validation failed.
First part of card (including partition table) is not written until everything complete. Otherwise there is a large chance Windows will be accessing the card and modifying things while we are still using it.

Hmm, thinking about it, the same bug may also occur in a few other circumstances if you are using uncompressed raw images.
Does it work correctly if you feed it an official Raspbian .zip file without uncompressing it first?

If so, then it likely the same bug. Which has already been fixed in git. But did not make it to a new release yet.

I am taking about this image:

https://downloads.raspberrypi.org/raspbian/images/raspbian-2020-02-14/2020-02-13-raspbian-buster.zip

When saving from .zip all seems to be OK.

Can you tell me please if there is any change log I could watch for changes? How do i know if new version appears on Raspberry Pi website?

Thank for clarifying the bug...

Can you tell me please if there and change log

During development the commit list has all code changes: https://github.com/raspberrypi/imagewriter/commits/
E.g. "Fix verifying on images that are not dividable by block size" is the change that should fix this.

Will leave the question whether there will be a more human readable (aimed at normal users rather than developers) changelog on the site, open for someone else.

Fixed and released, please go to the Raspberry Pi Downloads pages to update
