Hi all! I've attached part of my winnt.sif file below for inspection but my question is quite simple; if I have more than one HDD installed in a computer, how will WinXP's autopartitioning affect the two drives? Will it just delete the partitions on the first disk drive i.e. the master or will it erase all data? ;SetupMgrTag [Data] AutomaticUpdates=Yes AutoPartition=1 MsDosInitiated="0" UnattendedInstall="Yes" [unattended] UnattendMode=FullUnattended DriverSigningPolicy=Ignore OemSkipEula=Yes OemPreinstall=Yes TargetPath=\WINDOWS Repartition=Yes UnattendSwitch=yes WaitForReboot=No Thanks for your time!
