CallbackDisk™

CallbackDisk is a component for software developers lets you create virtual drives and disks, format them to FAT or NTFS, and mount as if they were physical devices.

Created by: EldoS Corporation

CallbackDisk consists of the system-level driver and user-mode API.

Driver

Virtual disk driver creates a virtual storage device, which emulates a physical storage.
The driver works on the system level and turns a storage into a "real" disk device with it's own file system. The "real disk device" is accessible in read-only and/or read-write mode by any application which uses system file management API.

The driver lets you make the mounted disk visible to the user or hide it from the user.
Unlike Solide File System Driver Edition SDK, the driver doesn't read or write the data from/to the physical location. Instead, the driver provides a callback mechanism, which lets you keep your data storage wherever you want (i.e. on remote computer, in memory or database record etc.).

User-mode API

User-mode API is simple and introduces just about ten functions, specific to driver management and storage mounting operations.
The API is needed only for driver and storage manipulation. All file operations can be performed using system file management API or framework-specific classes.

User-mode API is provided as a .NET assembly for .NET development, a library with one class for use in C++ and a component for use in Delphi.

Supported platforms

The drivers and user-mode API can be used on Windows 2000, Windows XP, Windows 2003 Server, Windows Vista and Windows 2008 Server. Both 32-bit and 64-bit (AMD64) systems are supported.
.NET user mode API requires .NET 2.0, .NET 3.0 or .NET 3.5.

Supported development tools

.NET component can be used with Visual Studio 2008 or Visual Studio 2005.
C++ library can be used with Visual Studio 6 or later.
VCL component is available for Delphi 5 to 2007, BDS 2006 (Delphi and C++ personalities), C++Builder 5 and 6, C++Builder 2007.
