I know that FDISK /mbr retains partition info.
A search on Microsoft bought up this :
"Do not use this command if any of the following conditions exists:
The disk was partitioned using the Storage Dimensions SpeedStor utility with its /bootall option.
More than four partitions exist.
Certain dual-boot programs are in use."
&
"Fdisk has an undocumented parameter called /mbr that causes it to write the master boot record to the hard disk without altering the partition table information."
I think that means your files stay intact
