#7 verify data written to USB from an image file.


I've been using your program on windows to write Linux filesystem images to a USB memory stick.

It would be really great if after you've written an image to a USB memory stick you could verify that the image has been written correctly. I imagine this would simply be a routine to read the data back and compare it with the image file that's just been written out. A simple "good"/"no good" result is all that is needed. This would be great for checking that the flash memory in the USB memory stick is behaving properly. Thanks.

This is really a feature request but I can't see how to add one, sorry...

    This should be able to be added for v1.0 release.

    I don't think we will use this as we already have some work on verify in progress. I'l take a look at it to see if there is something that can be merged into our changes. Thanks, though.

    Well, as a user I'm grateful to everyone who makes the effort to contribute to this project, but personally I think I'd prefer to have a separate "verify" button which gave definite feedback along the lines of OK/not OK. Thanks!

    Changed to pending. Code written and tested. I will need to do a little more fine tuning to the UI, debating having a checkbox for verify on read/write (i.e. clicking Read or Write will also run Verify afterwards). May reserve that for the next release, as a lot of people are looking for 1.0 (major bug fixes).
