About UDRW Technology
UDRW Technology is the Hagiwara Sys-Com patented USB storage device technology that combines the flexibility of a "Read and Write" area (Removable Disk partition) and the benefits of a "Read-Only" area (CD-ROM partition) into one small compact package.

Since the inception of UDRW Technology, Hagiwara has continued to expand features and the functionality of UDRW, such as new form factors (bNAND2 One-Chip and bNAND2 USB DOM), new data protection features (Password Lock, Secure Erase and Write Protection) and the "Hidden Memory Zone".

By doing so, UDRW Technology allows the USB Flash Drive to be combined with previously unrelated applications including software, hardware and services to yield novel and invaluable creations.

User Selectable Drive Configurations

- Write Protection - Password Lock - Hidden Memory Zone*
*Purchase of UDK Kit required for these functions

2. Removable Disk + CD-ROM (+ Hidden Memory Zone)
Removable Disk
Removable Disk
CD-ROM
CD-ROM
Data stored in the CD-ROM partition is protected from accidental or intentional deletion, while stored content in the Removable Disk partition allows full read/write access.
Can utilize data protection features
- Write Protection - Password Lock - Hidden Memory Zone*

*Purchase of UDK Kit required for these functions

3. CD-ROM + Removable Disk (+ Hidden Memory Zone)
CD-ROM
CD-ROM
Removable Disk
Removable Disk
This configuration allows for the BIOS to recognize the CD-ROM
partition first (LUN 0) and the Removable Disk second (LUN 1).
Allowing for CD-ROM boot.
Can utilize data protection features
- Write Protection - Password Lock - Hidden Memory Zone*

*Purchase of UDK Kit required for these functions
Factory Set Drive Configuration

1. USB-HDD*
HDD
Fixed Drive
OS recognizes the device as a fixed disk drive.
Allowing for USB-HDD OS Boot.
Can utilize data protection features
- Write Protection

* In USB-HDD configuration, the CD-ROM, Removable Disk and Hidden Memory Zone not available
Data Protection Features
1. Write Protection*
By utilizing the GPIO Write Protect Pin, contents the Removable Disk Partition or the Fixed Drive can be protected from accidental or intentional overwrites or deletion.

2. Password Lock
Restrict access to the Removable Disk partition using a Password-based lock.

3. Hidden Memory Zone**
Invisible to the OS, the Hidden Memory Zone can store such data as:
- Passwords
- Credentials
- Serial Numbers

* Only available for bNAND (One Chip) and bNAND USB DOM
** Purchase of UDK required for these functions

UDRW Development Kits

Two types of development kits are available depending on your application needs:
STK G4 and UDK G4.

UDRW G4 Starter Kit (STK G4)
The STK G4 CD-ROM contains utility software tools that allow developers to modify and/or confirm the settings of the bNAND devices. Optional UDK is required to utilize the advanced features such as read/write access to Hidden Memory Zone, Obtaining Unique ID, etc.
The STK G4 Kit Contains:
- STK G4 Writing/Setup Utility CD
- 3pcs. of hardware

UDRW G4 Development Kit (UDK G4)
The UDK G4 CD-ROM contains a group of function libraries (Dynamic Link Library) that controls the bNAND devices. The library set allows the developers to utilize advanced features of bNAND such as read/write access to Hidden Memory Zone, Obtaining Unique ID, etc.
The UDK G4 Kit Contains:
- UDK G4 Library CD
- STK G4 Writing/Setup Utility CD
- 3pcs. of hardware

UDRW Application Examples
Windows Autorun Function

Firmware level CD-ROM emulation allows you to launch the application automatically when it is connected to a Windows OS computer.

Unlike legacy CD-ROM disks, the UDRW is completely scratch-safe and portable.
UDRW can also extend the battery life of laptops due to the lack of any moving parts.
