Fast navigation points

You don't need to guess what is the sector of root directory on FAT volume is or where is $MFT record on NTFS partition located. Simply use fast navigation points set up in the menu. When Disk Editor opens an object, the most important areas are detected and automatically added to the list. They include boot sectors, FAT tables, root directory, $MFT and $MFT Mirror and others.

Filling selection with a pattern

It might be handy to fill an area on the disk with particular data. Besides simply zeroing an area by providing 00 as hexadecimal value you can specify any hexadecimal or text pattern for better flexibility.
