SBS 2008 Backups Failing

We replaced a dead USB drive with a new Seagate 3TB desktop hard drive.  The backups are failing with the following error 2155348010 One of the backup files could not be created.

I did some research and many forums state that the allocation size of the external drive should not be 4096 bytes and recommend reformatting at 512 bytes.  When I right click on the drive to format, I don't have 512 as an option.

Any ideas on how to format the drive using 512 bytes?

That is the reason on why you cannot backup.  The onlything you can check is to see if that particular drive has a 512byte emulator.  Some drives have this ability and if it doesn't im afraid you will have to get a different drive.

You would use Seagates Wizard:  http://knowledge.seagate.com/articles/en_US/FAQ/218619en/?q=3TB&language=en_US&c=Products%3ASerial_ATA_Drives_Seagate_Barracuda&fs=Search&pn=1

You might want to check on the model you have to see if its compatible

I downloaded and ran the Seagate Wizard on an SBS2008 server but got the following error.  "this product is incompatible with a server operating system"

Can I install external drive and Seagate Wizard on a desktop running Windows 7, format the drive using the emulation, then plugging it back into the server?
