Norton Save and Restore 2.0 using FAT32 and NTFS file systems

Hello,

 

I occasionally have trouble with NSR 2.0 not completing it's operation.  It gets about 95% (or more) completed and hangs; leaving the OS in a unstable mode as I have to reset the computer via the reset/power button; I cannot shutdown the computer via Windows dialogs boxes.  NSR appears to successfully create the backup file, but running the NSR browser integrity check yields a checksum error (actually, all my C backups are getting this checksum error; not good; but I can see files when I browse the file structure).  I am running XP Pro with a C drive formatted FAT32 and the external target drive formatted NTFS. 

 

I am beginning to think that this is related to my computer being in switch user mode when the backup is completing; i.e. computer has automatically gone to the logon screen (but has not logged me off).

 

In using the Norton chat service, they are telling me that the issue is that I am backing up using 2 different disk formats (FAT32 on the source drive and NTFS on the target drive).  This doesn't make sense to me.  First, I have not seen anything in the documentation regarding this limitation, plus the software allows me to do this and I would think it would prevent me from this operation if that is a limitation (note: I would convert C to NTFS, however want to make sure I have a solid backup in case something goes wrong).  Why would the underlying file system structure be a factor... the target file is just a file.  Can someone help me understand this?  Am I at risk with my back?
