Issue: The backup error which is "One of the backup files could not be created. Detailed Error: The request could not be performed because of an I/O device error"
Backup started at '10/12/2012 8:33:44 PM' failed with following error code '2155348010' (One of the backup files could not be created.). Please rerun backup once issue is resolved.
Follow the steps to troubleshoot the issue:

1. Normally Windows 2008 server backup will not work with external HDD formatted with 4K (4096 bytes) Logical sector sizes.
2. So need to change the Logical sector sizes to 512 bytes by formatting it with WD Quick Formatter.
3. Download WD Quick Formatter tool from the following link http://wdc.custhelp.com/app/answers/detail/search/1/a_id/3868
4. Using the WD Quick Formatter tool, select the Factory Default configuration/Most Compatible (Vista or Later required) to reformat the drive to default manufacturer's settings.

          a. XP Compatible—If you are running Windows XP and connect a WD external drive that is larger than 2TB, it will not be recognized by your system until you select the XP compatible option to configure it and change the block size. After running the application using the XP Compatible option, the drive will be recognized and can be used on Windows XP, Windows Vista, and Windows 7.
         b. Most Compatible (Vista or Later required)—If your WD external drive (larger than 2TB) has been configured to change the block size using the XP Compatible option, you might have problems with some applications. If this happens, run the Quick Drive Format application again and select the Most Compatible option to return to the manufacturer's default block size settings.

1. This is how the drive appeared before format:

C:\Windows\system32>fsutil fsinfo ntfsinfo H:
Bytes Per Sector : 4096
Bytes Per Physical Sector : <Not Supported>
Bytes Per Cluster : 4096
Bytes Per FileRecord Segment : 4096

2. This is how the drive appeared after the "Factory Default" format:

C:\Windows\system32>fsutil fsinfo ntfsinfo H:
Bytes Per Sector : 512
Bytes Per Physical Sector : <Not Supported>
Bytes Per Cluster : 4096
Bytes Per FileRecord Segment : 1024
