DiskSpy 2.0

DiskSpy enables you to view every sector of any installed hard disk drive regardless whether these sectors are bootsectors, partition tables, file system entries or simple data files.

Free Edition

The Free Edition of DiskSpy allows to display every sector of any installed IDE harddisk. Various display modes allow a better overview of the saved data, e.g. a FAT table can easily be read in the doubleword view, where the file sizes, timestamp of last changes and the corresponding sector numbers are displayed. You also can switch the ASCII display to a full 8-bit-display, which shows all control characters as well as the extended ASCII characters in plain text. These characters are usually displayed as a dot to minimize distractions when reading the sector. Besides the always visible short info DiskSpy can show extended information about the installed hard disk drives. Besides information like capacity, heads, sectors and cylinders it shows available DMA, UltraDMA and PIO modes also cache size and serial numbers of a hard disk.

In addition to the features of the Free Version the Professional Edition also allows you to edit the sector's contents. This can be done either in the hexadecimal view or in the ASCII view, all changes are made visible with another color. A useful search function is also available, which is much improved in comparison with the free version: it offers a search function for any character string in both directions, as well as inverted search (find the first non-matching character) for byte-, word- and doubleword patterns.
