One of my most valuable software tools has always been Norton DiskEdit from Norton Utilities/Symantec Systemworks. I have used it for years for so many things, including, but not limited to learning file-systems and data-recovery.
I am now in search of a similar tool that can let me view FAT and NTFS disks at a low and high level under Windows.
Runtime Software has DiskExplorer, but unfortunately, it is limited in a number of ways. Particularly annoying is that it does not really let you view the disk as structured. For example it does not let you see directory entries from a directory that is fragmented like DiskEdit can without first doing a too-exhaustive scan—which doesn’t even work for FAT partitions that have cluster sizes <4KB.
I have tried the other suggestions, but most of them are not going to cut it because they only let you view and edit disk sectors and are not aware of disk structures like directory entries, partition tables, boot sectors, FAT, $Mft, inodes, etc.
Does anyone know of a Windows alternative of a Norton DiskEditor?
