Windows backup sorunu

Merhaba, 

Windows Server 2012 R2 Foundaion Edition kurulu RAID1 yapısında Dell marka bir sunucumuz var. 
Windows Backup aracılığı ile portable dikimize yedek almaya çalıştığımızda her seferinde alttaki hatayı veriyor.
"the sector size of the physical disk on which the virtual disk resides is not supported" 
Nerede hata yapıyor olabiliriz?
