Pro Data firmware is protected by redundancy against corruption and power loss during the update process, however situations can still occur in which the system is unable to boot using either version stored on the device. In these cases, the system can be recovered by booting the system in a failsafe mode where updated firmware is provided by the host computer: Firmware Recovery mode.
If Pro Data is unable to boot and connect to your computer, contact iodyne Support first to get help. If the support technician instructs you to enable DFU mode on your device for recovery, you'll need a paperclip or metal pick of about the same diameter. Bend the paperclip so that one end forms a straight metal pick at least a half-inch long. Now follow these steps:
- Remove power from Pro Data. Unplug the power cord from Pro Data, remove the power supply AC line cord, or turn off the power strip connected to the Pro Data power supply, so the device is fully powered off. Note: Leave Thunderbolt cables connected to Pro Data and your computer.
- Locate the pinhole access to Pro Data Firmware Recovery mode button, to the left of its Thunderbolt ports and opposite the power connector, shown below:DFU button access pinhole
- Insert the paperclip or pick straight into the pinhole slowly and firmly, and continue pressing until you hear a single “click” to engage the Firmware Recovery mode button. Remove the paperclip.
- Restore power to Pro Data. You will notice that the LED blinks blue instead of purple, indicating Pro Data is booting in Firmware Recovery mode. If the LED instead blinks purple on boot, return to Step 1 and repeat the procedure. The LED will turn solid blue when Pro Data is ready to connect to your computer.
- Launch iodyne Utility. Once Pro Data has booted in Firmware Recovery mode, indicated by a solid blue LED, iodyne Utility will show a dialog box indicating Pro Data is detected in DFU mode, prompting a firmware download and recovery. Follow the instructions given to you by your support technician.
- Confirm successful firmware recovery. Once firmware recovery is complete, repeat Step 3 to disable Firmware Recovery mode. Reset your device using the Devices menu in iodyne Utility or remove and restore power to Pro Data. Confirm that the LED blinks purple to indicate normal boot operation; if the LED blinks blue, repeat this step.
Note: When Pro Data is in Firmware Recovery mode, your containers and filesystems are protected from access during the recovery procedure to keep your data intact. Once the recovery procedure is complete and Pro Data is returned to normal operation, your containers and filesystems will again be present and accessible.
