DriveImage XML – Could not flush write buffer

We get email all the time about DriveImage XML. One of the main ones is the error “Error – Could not flush write buffer …..”.

Users say that they have more than enough room on the drive but the backup fails every time after copying about 4GB. The problem is that you are copying to a FAT32 drive. FAT32 does not allow files to be larger than 4GB.

You can find more information about this at You have two solutions to this problem, the first one is to format the drive to NTFS which is preferred by Windows XP, or you can just turn on the Split Large Files option in the software.
