There are many ways and tools to hide or protect important data on a USB Flash Drive.However a simple format of the USB Flash Drive can erase the important data.Using Fbinst, a hidden partition can be created to store important data.This hidden partition stays even after formatting the USB Flash Drive.http://feeds.feedburner.com/~r/agnipulse/~4/1u3VD7Nc1Go

WARNING:
possibly mis-leading message for the "casual onlooker" :ph34r:.

Need to highlight these two sentences in "Additional Tips":

  • The Hidden Partition remains even after formatting the USB Flash Drive from Windows Explorer or Dos.In fact all formatting tools which format based on drive letter will not affect the hidden partition.
  • The hidden partition may get deleted only if some advanced Formatting tools or Partitioning tools are used.




Obviously a partition (hidden or viewable) will stay if you FORMAT a (another ;)) drive (or partition or volume) by it's drive letter.
BUT if you re-partition the disk (or if you prefer use disk management on the actual disk device) this is not always true.
If you use FORMAT (from command line or GUI) you select a drive letter i.e. a \\.\LogicalDrive.
If you access disk management or diskpart you may apply changes to the disk or \\.\PhysicalDrive.

Quick reminder:
On partitioned device:
disk is the "whole thing" and contains drive(s) or partition(s) or volume(s)
\\.\LogicalDrive=drive=partition (if Primary)= volume <-this is what gets a drive letter
\\.\PhysicalDrive=disk

On non-partitioned device:
disk is the SAME as drive or volume
\\.\PhysicalDrive=\\.\LogicalDrive=drive= volume <-this is what gets a drive letter
