Log error on Client : "CreateFile of volume 'A:' failed. - sendMBR. Errorcode: 2"

Hello.
I have an issue on three PCs clent Windows.
All worked fine until last week.
then some days, the clients have an error:

08.02.17 15:23
Could not read MBR. Error message: CreateFile of volume ‘A:’ failed. - sendMBR. Errorcode: 2
08.02.17 15:23
Error getting MBR data
08.02.17 15:23
Request of image backup failed. Reason: Opening filesystem on device failed. Stopping.
08.02.17 15:23
Backup failed

The UrBackup server is on a Linux Centos operation system, the server versione 1.4.14,
Each clients have installed the version 2.0.34. and are all in windows 7.

The strange is that all was going well, something could have changed the settings in the clients.

anyone has had a similar issue?

someone could help me?

thanks
Pier

Can you check your backup drives and make sure there is no drive A: or * written there? I doubt your clients have floppy drives. Alternatively, add A: to list of drives to back up and add optional flag to it.

Hey !!!
thanks … ur comment is RIGHT.
I modified a settings in the Server UrBackuo and i wrote bad the value in the “volumes to backup”. :(((
the right setting is “ALL_NONUSB” my bad setting was “ALL_NONSUB”.

thanks a lot and sorry for the stupid issue.

thanks again AckRite
bye
