o create a report file with failed block details when bad blocks are found
o use the umount/remount trick to make the volume reappear post formatting
o set keyboard according to locale in DOS
o allow selection of one of the existing compatible volume (keep existing MBR) / full repartitioning (overwrite MBR)
o FreeDOS integration
o Enable compression for NTFS
o Create a report file with failed block details on bad blocks
o Integrate FreeDOS
o Allow the provision of external DOS files
o Set DOS keyboard according to locale
o Allow selection of one of the existing compatible partitions (keep existing MBR) vs. full repartitioning (overwrite MBR)
o Bootable NTFS/exFAT (http://sourceforge.net/projects/grub4dos)?
o GPT support?
o Enable compression for NTFS?
o disable indexing support on NTFS?
o FAT32 formatting for volumes > 32 GB?
