Attaching a new Buffalo Drivestation 3TB Velocity USB 3.0 backup drive (HD_LXU3) to an old Windows Server 2008, which is part of Small Business Server 2008, reminded us of an error we'd not seen for a few years.
The standard Windows Server backup failed to run within a couple of minutes, despite having been configured for the new drive.
The Event Log showed an Exchange error from source msexchangeis with event id 9782. This was a little misleading, because all the exchange esetuil diagnostics and repairs will show no fault. A little further on in the event viewer you might also see an error that the backup failed with following error code '2155348010' and event id 517, which is a little more useful.
The fault lies with the fact that the Server 2008 Backup doesn't support larger capacity drives with the newer Advanced Format using 4096 byte sectors. It will only backup to a drive formatted with 512 byte sectors. Note that this is referring to the drive format sector size, not the volume or partition sector size.
If you're lucky, the USB drive you've bought had a download that will allow you to reformat the drive. Western Digital (WDC) have the WD Quick Formatter utility. More background detail and a link in this thread https://social.technet.microsoft.com
Buffalo have a similar utility, but its not available on the UK support page! Instead, if you head over to their Japanese support page http://buffalo.jp/support_ap/support/products/hd_lxu3.html and download the DriveFormatter2 program (its in English), you can reformat with 512 byte sectors. Select the correct drive and choose option 2: NTFS (Win 8, 7, Vista)
