Yes, a direct connection to the PR2100 is possible, but how you connect depends on what you mean by “direct” and how you plan to use the device. The PR2100 is most commonly known as the Buffalo Tera Station PR2100 NAS (Network Attached Storage), so the explanation below is based on that model.What “Direct Connection” Means for the PR2100A direct connection usually refers to connecting the PR2100 without a router or network switch, such as:Connecting the PR2100 directly to a computerConnecting via Ethernet without a routerAccessing the PR2100 without internet accessThe PR2100 does not work like a USB external hard drive. It is designed primarily as a network-based storage device, but limited direct-connection options do exist.Direct Ethernet Connection to a Computer (Yes, Possible)You can connect the PR2100 directly to a computer using an Ethernet cable, but there are important limitations.How It WorksConnect an Ethernet cable from the PR2100 directly to your computer’s Ethernet portManually configure IP addresses on both devices (static IP setup)Access the PR2100 using a web browser or file explorerLimitationsNo automatic IP assignment (no DHCP without a router)Requires manual network configurationNot ideal for beginnersNo multi-device accessThis setup is typically used for initial setup, troubleshooting, or temporary access, not long-term use.Direct USB Connection (Not Supported)The PR2100 cannot be used as a USB storage device.USB ports on the PR2100 are for:External USB drivesUPS devicesBackup storageYou cannot connect the PR2100 to a computer via USB for file accessSo if you’re asking whether you can plug the PR2100 into a computer like a portable hard drive, the answer is no.Recommended Method: Network (Router-Based) ConnectionBuffalo designed the PR2100 to work best when connected to a router or network switch.BenefitsAutomatic IP addressingEasier setupAccess from multiple computersSupports file sharing, backups, and user permissionsWeb-based management interface works smoothlyTypical SetupPR2100 → Router (Ethernet)Computers → Same router (Ethernet or Wi-Fi)Access via browser or mapped network driveThis is the most stable and supported configuration.Direct Access for Initial SetupDuring first-time setup, a “direct” connection may be used:Connect PR2100 to routerAccess setup interface from one computerConfigure RAID, users, and foldersEven though this is still network-based, it’s often referred to as “direct access” by users.When a Direct Connection Makes SenseA direct PR2100-to-computer connection may be useful if:You are setting it up for the first timeYou are troubleshooting network issuesA router is temporarily unavailableYou need short-term, single-computer accessFor everyday use, it’s not recommended.Conclusion✔ Yes, a direct Ethernet connection to the PR2100 is possible✘ USB direct connection is not supported✔ Best performance comes from using a router or switchThe PR2100 is a network storage device, and while limited direct connections can work, it performs best as part of a local network.

After upgrading drives:Use the WD My Book Duo software to configure RAID.Select the appropriate RAID type (RAID 1 for redundancy, RAID 0 for speed, or JBOD for separate volumes).Follow the on-screen instructions to rebuild or create the RAID array.Once the RAID is set up, your system will recognize the drive as a single volume, allowing you to access files.Step 6: Access FilesAfter completing installation, initialization, or RAID setup:Open File Explorer on Windows or Finder on Mac.Locate your MyBook Duo drive under This PC or Locations.Transfer files, create folders, or manage storage as needed.At this point, your upgraded MyBook Duo hard drive is ready for regular use.Final ThoughtsUpgrading your MyBook Duo hard drive enhances storage and performance, but accessing files requires careful steps. Always check drive recognition, back up old data, and configure RAID correctly. By following these steps, you can access files after upgrading MyBook Duo hard drive safely and efficiently.
