\ ----------------
\ This GUI program is primarily for safely writing a bootable ISO image to a USB flash drive, \ an operation devious & potentially hazardous when done by hand. As a bonus, it can also back up the\ entire previous
contents of the flash drive onto the hard disc, and restore the flash drive \ to its previous state subsequently.
\ It gives also a feature for formatting the USB device.
\
\ IsoDumper can be launched either from the menus, or a user or root console with the command 'isodumper'.
\ For normal users, the root password is solicited; this is necessary for the program's operation.
\ The flash drive can be inserted beforehand or once the program is started. In the latter case, a \ dialogue will say that there is no flash drive inserted, and allow a 'retry' to find it once it is.
\ (You may have to close any automatically opened File Manager window).
\
\ The fields of the main window are as follows:
\ - Device to work on: the device of the USB flash drive, a drop-down list to choose from.
\ - Write Image: to choose the source ISO image *.iso (or flash drive backup file *.img) to write out.
\ - Write to device: This button launches the operation - with a prior warning dialogue.
\ The operation is shown in the progress bar beneath.
\ - Backup to: define the name and placement of the backup image file. The current flash drive \ will be backed up to a disc file. Note that the entire flash drive is preserved, regardless of its \ actual contents; ensure that you have the necessary free disc space (the same size as the USB device). \ This backup file can be used later to restore the flash drive by selecting it as the source *.img file to write out.
\ - Backup the device: launch the backup operation.
\ - Format the device: create an unique partition on the entire volume in the specified format in FAT, \ NTFS or ext. You can specify a volume name and the format in a new dialog box.
