Floppydisks, Harddisks, CD-drives, RAM-Disks etc.
With DMT you can edit data on any drive (hexadezimal and ascii).
Supports all block-orientated devices, such as FloppyDisks,
Harddisks, RAM-Disks, CD-ROMs, File-Partitions, etc.
All Amiga-FileSystems (OFS, FFS, INTL OFS, INTL FFS, DirCache OFS
and DirCache FFS) are supported as well as partitions with
blocksizes other than 512 bytes and you can edit the harddisk's
Rigid-Disk-Blocks.
You have additional functions, for example search data, find file-
headers, jump to Parent-/Header-/DirChache-/... Blocks, etc.
You may also edit data in files. With DMT it is possible to edit
files that are larger than the availible RAM. In the FileMonitor
you may search for data (hex and ascii).
With the MfmEditor you may even edit the MEM-Encoded Data on
Floppy-Disks (the format, data is stored physically on the drive).
It has additional features, such as sorting the data, move data,
index-sync read/write (for PC-Disks), check the checksumms (for
trackdisk, diskspare and mfm.device disks), ...
Read-/Write-Errors on Floppy-Disks (only DFx:, trackdisk.device) may
be corrected using RepairTrack.
On DD-Disks and compatible File/Ram-Disks (880 KB) you can view/edit
the BAM (Block-Availible-Map) with the BamEditor.
Deleted files can be recovered using Undelete.
If you have errors on a filesystem (disk not validated) you may use
Salvage to restore all files of a Partition.
