Error code: 21 Failed to read data from the file

Hi there,

I'm trying to do a FullBackup to a CIFS Share of a TravelMate 5735Z to a Thecus N2200 NAS.
Installation worked without a problem.
Windows Backup works normaly.
When I try to do a BackupJob with Veeam I get an Error Code 21 after 5-8 Minutes.

30.12.2014 18:35:46 :: Error: Das Gerät ist nicht bereit. Error code: 21 Failed to retrieve info about disk geometry. Failed to open emulated disk. Failed to open disk for read. Failed to upload disk. Agent failed to process method {DataTransfer.SyncDisk}.

Hello toonruler,
Did you reboot after setup was completed?

Hi toonruler,
I’ve checked your case – the last response was on 1/7/2015. I’ll see what I can do.

Anyone found a solution for this?
Got the same error on a Win 7 Pro Notebook, when trying to backup to an exrternal USB-Drive.

Armin,
The OP's issue was resolved by a private hotfix which is now merged in the latest Endpoint upgrade. Can you please elaborate what version are you using? Thanks

reformatted USB-Drive, deinstalled and reinstalled Veeam Endpoint Backup,
but still the same error:
