Introduction

Disk-XRay is an utility to browse the real contents of magnetic disks. It displays the raw contents of sectors.
It offers classical navigation functions to display the real contents of data sectors.
Disk-XRay manages physical hard disks, that is below the partitionning scheme.

User Interface

The user interface is the same as classical hexadecimal editors:

Analytical Display

Disk-XRay recognizes following data structures, and displays them accordingly:

• Macintosh Volume Descriptor
• Macintosh Partition Table
• Macintosh Master Directory Block
• Macintosh B Tree Header
• Macintosh B Tree Nodes
• Master Partition Block
• Boot Sector
• EFI Partition Table
• Etc.

Disk Access Method

To access the drives, we use the Aspi layer under Windows 95/98/ME and NT. This layer must be up to date (4.57 or higher).
Under Windows 2000 and XP, we use a service called lsdiorw.exe, which must be installed from an administrator account. See some comments on this service.

Disk Editing

Disk-XRay features an Edition mode, where you can write onto the disk, sector by sector. Needless to say that this feature can be very dangerous, but also very powerful.

• File-XRay, low-level file explorer.
