Access PwrPak7 Internal Memory with a Computer

The PwrPak7 has 16 GB of internal Flash memory. This memory is formatted as FAT32 with a cluster size of 16 kB.

When a computer is connected to the TRANSFER port on a PwrPak7, the computer can access the internal memory on the PwrPak7. If the internal memory is not in use (FILECONFIG CLOSE), control of the internal memory is transferred from the PwrPak7 to the computer. If the internal memory is being used for logging (FILECONFIG OPEN), control is not transferred to the computer. This prevents an interruption of the logging. To allow the computer to access the internal memory, stop logging to internal memory (FILECONFIG CLOSE).

When the computer is disconnected from the TRANSFER port, control of the internal memory is transferred back to the PwrPak7. The PwrPak7 then checks the file system on the internal memory for errors. If any errors are found, the PwrPak7 attempts to correct them. This may result in files being placed in the Lost and Found folder in the root of the internal memory.

To reduce the likelihood of internal memory corruption or data loss, the following is recommended:

1. Always use the Eject option on your computer before disconnecting the USB cable from the PwrPak7.

2. Before powering off the PwrPak7, use the FILECONFIG CLOSE command to ensure there is no activity on the internal memory when the power is lost.
