Problem: I don't see a partitions.ini file on my Real-Time (RT) target which has an IEEE-1394 external drive connected to it. How do I retrieve the drive information without opening a reference to this file?Solution: Before LabVIEW RT 8.0, an IEEE-1394 drive connected to an RT target would create a partitions.ini file which was used to discover drive information, including the drive letter assigned to the external drive. The external drive would always be assigned this drive letter once this file was created, even after being removed and reattached. With LabVIEW 8.0 and later this file is no longer created. This means that IEEE-1394 drives will be dynamically assigned the first available drive letter every time they are connected to the RT controller. Note: Drive letters A-F are still used by the OS and won't be assigned to IEEE-1394 drives. The Get Volume Info VI is still used to retrieve information about each drive. Use the example linked below to list all the 1394 drives attached to your RT target.
