DiskPatch is a menu driven DOS program designed to help you solve a wide range of harddisk problems.

Mass data loss, a situation where access to an entire disk or partition is lost, is often caused by damage to meta structures such as the MBR, Partition Tables, LDM, or the Boot Sector of an individual partition.

By repairing those structures with DiskPatch, data can be made accessible again.

Another common cause for data loss is unreadable sectors; while a few read errors may only have minor consequences and only prevent access to one or more files, large blocks of unreadable sectors can prevent access to individual volumes or even entire disks.

In that case you can use DiskPatch to clone a hard disk (even when conventional cloning tools fail due to bad sectors or file system errors), scan the disk surface for read- and write errors and possibly fix bad sectors.

DiskPatch allows you to edit (patch) your disk using the built-in disk editor, partition table editor and boot sector editor. It also offers basic partition management (hide, unhide, set active) features.

You can 'prepare' for data loss caused by damage to the MBR, partition table sectors, boot sectors, or LDM (on Windows 2000/XP Dynamic disks) by using DiskPatch and it's unique proprietary backup system to create on-disk backups of those structures.

Once a backup exists, damage to any of the previously mentioned disk structures can be easily fixed by restoring the backup.
