RESOLUTIONS:

There are two ways to go around this:

  • You can split the data so that the files do not exceed 4GB.

Please go to Where to Backup->Enable Multi-Drive Spanning->Use Fixed Split Size->2GB

  • Convert the System Format from FAT32 to NTFS:

Standard Windows utility that is called CONVERT serves this purpose
Just go to the Start->Run->Cmd (Command Prompt) and execute the command:

            C:\> CONVERT  C:  /fs:ntfs
Where C: is a name of the drive you want to convert. 
After machine re-boot conversion process will start and you'll have your FAT32 converted to NTFS without data loss. 

 

To check Drive File System:

  • My Computer->Highlight the drive->Left hand pane->File System

 

 

  • My Computer->Highlight the drive->Properties->File System
