Windows 7: windowsback faulty on 2tb external hdd

does anyone have a workaround for the following problem?



When Windows Vista and Server 2008 were released, Microsoft turned its back on tape backup. The built-in backup utility only backs up to hard drives. Windows 7 and Server 2008 R2 continue this policy. The recommended strategy for Small Business Server 2008 and 2011, for example, is to have a bunch of external USB drives and to use them in rotation.
Windows Server Backup, and its command-line version wbadmin, work well enough, but users with growing storage requirements have been buying larger external drives. That seems fine: external USB drives with 2TB and 3TB capacities are now commonplace. Except that they often run into problems when used with Windows Server Backup. You might see error 2155348010 or 0x8078002A, or “The request could not be performed because of an I/O device error”, or some other error.
The reason is that most of these large drives have a 4K sector size, rather than the older 512 byte sector size. You can get a patch for Windows 7 and Windows Server 2008 R2 that fixes most problems, but it does not fix the backup issue.
