verification of restored image

Post by Calvin » Tue Jan 29, 2013 11:17 pm

Hi Alex,

thanks for your great tool. :D
I am using it for restoring images on USB stick and Compact Flash card.

When restoring images with your GUI tool, a 'success' message is displayed.
What kind of verification of the written image do you perform?

Thanks for your answer

After there Restore there is no special bitwise verification afterwards. The completion message just means, that the Windows i/o rouines completed all write operations without error. To make a verification, the newly written image would have to be read again and compared against the master image. USB Image Tool doesn't do this currently.

However, you can perform a verify yourself, by making a backup of the newly written flash drive. You can either let USB Image Tool create a MD5 hash and compare it with the one, you might have from the original image or make a file compare with an external tool.
