Actual results may vary depending on system environments, drive media used, or other factors.

NTFS is the default file system on the cartridge. If you are using Linux, the cartridge that comes
with your system will need to be reformatted to support a file system that is compatible with a
Linux-based operating system (see the section “RDX Cartridge File System Considerations” in
the appendix).
1.3 Supported Media
The RDX system supports any RDX cartridge. RDX cartridges are available in different capacity
configurations, depending on your storage requirements.
