I am currently testing 12.5.9 of Novabackup Professional. I have a very strange problem.
After I installed a new Windows 7 system with all necessary updates, I made a full backup of my C: partition of an internal harddrive to a USB-harddisk . The partition had about 100GB and ended up with a round about 15 GB backup file.
After that I started to install all my necessary software "for every day usage". I wanted to make another full backup. Almost at the end, the green bar that is showing the process already touched the right side, Novabackup stopped showing an input output error. It claimed that there might be a harddisk error (damaged sectors). I checked the partition with Windows Scandisk AND a special Western Digital tool. No errors! Even the SMART values show no errors.
Novabackup tells me that the input output error has occured on the internal harddrive C:. The USB-harddrive works perfectly for sure!
Okay, as I said, the error occured just when Novabackup was about to finish the process. Does this mean that the error is located at the end of the partition? So, I started a partition manager and made C: about 3o GB smaller in order to exclude the possible error message at the end of the partition.
Then I reinstalled the backup file to the smaller C: partition, reinstalled all my software "for every day usage" and wanted to make a new backup!
BUT I get the same error once again. When Novabackup ist about to finish, I get the input output error. I can then ignore the error or cancel the backup process.
What does all that mean? It doesnt make sense to me.
My first backup process showed no errors at all!
My second backup ends up with input output errors.
